Most-missed Montana DMV rules

These are the numbers and rules that trip up new drivers most often on the real Montana knowledge test. Every fact below comes from our free Montana DMV practice test question bank, which has 212 questions across 9 topics.

Speed limits

The manual describes a narrow passing exception on a two-lane road: a vehicle may exceed the speed limit by 10 mph to overtake another vehicle and return safely to the right lane. Light traffic or being late does not create that permission. Even during a pass, the driver must make sure the maneuver can be completed safely and must return to the proper lane.
A posted speed limit is not a promise that the same speed is safe in every condition. Montana says to consider the road and weather and to drive below the limit when conditions are bad. Keeping the exact posted number can be too fast on ice, in rain, or when visibility is poor. Increasing speed makes control harder, and police presence does not determine when a reduction is needed. Use the limit as a ceiling, then choose a safe speed.
Montana directs drivers on roads with three or more lanes going the same way to stay in the right lane except when passing. The manual adds that the center travel lane should be used when a lot of traffic is entering, so the center lane is a situational choice rather than the normal lane. Neither the left lane nor preparing for a left turn is the stated exception. Look ahead for entering traffic and change lanes smoothly when needed.
Montana doubles traffic fines in work zones, and exceeding the posted work zone speed is a violation. There is no single statewide work zone speed limit; the transportation department, a local authority, a utility, or a contractor sets the limit for each zone. The manual gives no exception for zones without visible workers and no night only tripling. Driving in a way that endangers people or property, or purposely striking a traffic control device, can also bring a reckless endangerment charge.
Montana law lets school zone speed limits be set as low as 15 mph, and local authorities decide the posted speed and how many blocks around a school the zone covers. Floors of 20 or 25 mph are wrong because the law allows lower limits, and 5 mph is below the figure the manual gives. Fines are doubled in all school zones throughout Montana, so speeding near a school costs twice as much. Watch for children near schools and parks day and night.
A driver in a Montana funeral procession may not exceed 55 mph on a highway where the speed limit is 55 mph or more, so a 65 mph posting does not let the procession travel at 65. On other streets and roads the rule works the other way: procession drivers may not go more than 5 mph below the posted limit, which is a minimum, not a cap. The manual sets no 45 mph limit. All headlights and taillights must be on.
The manual gives rough speed cuts for slippery roads: reduce speed about 10 mph on a wet road, cut it in half on packed snow, and slow to a crawl on ice. A 10 mph reduction is the wet road guidance, so it is too little on packed snow, and 5 mph is even less. New tires do not remove the need to slow down. Use snow tires or chains when the road has snow on it.

Right of way

Traffic already circulating in the roundabout has the right of way, so an entering driver must yield before joining. The driver should keep right of the center island and should not stop when the path is clear. Forcing entry or driving left of the island reverses the intended flow. Slow down, look left, yield, and enter only when a safe gap is available.
At a four-way stop, the driver who reaches the intersection first gets to go first after making a complete stop. Vehicle size, a headlight flash, and a left turn do not create priority under this rule. Arriving first is not permission to rush: check that the intersection is clear, then proceed while remaining alert for pedestrians and other road users.
After yielding to an emergency vehicle, a Montana driver must pull to the right and remain stopped until that vehicle has passed. A green signal does not release the driver, and the manual gives no one-minute timer or permission to wait for another motorist’s gesture. The stop protects the emergency route and gives the responding vehicle room to proceed. If the driver is in an intersection, clearing it comes first, followed by pulling over and stopping.
When meeting or passing a stopped school bus with red lights flashing, a driver must stop at least 30 feet away and wait until the red lights turn off. Children may be in the roadway, so seeing no child is not an exception. The opposite direction also generally must stop unless the bus is on a different road or in an adjacent loading zone where pedestrians cannot cross.
A pedestrian using a guide dog or carrying a white cane has absolute right of way. Drivers must not use the horn because the sound could confuse or frighten the blind pedestrian. Limiting the protection to signals or marked crosswalks understates the rule. The safe response is to yield, remain patient, and give the pedestrian space to cross without pressure from the vehicle.
At an uncontrolled intersection, Montana's general priority rule is to yield to a vehicle coming from the right, while remaining prepared to yield to prevent a crash. The left-side choice reverses the stated direction, and speed does not determine this basic priority. Uncontrolled means there is no device assigning movement, not that drivers may continue without checking. Ease off the accelerator and cover the brake as you look both ways.
A left-turning vehicle crosses the path of oncoming traffic, so the driver must yield to an oncoming car going straight ahead. Signaling communicates intent but does not grant priority or make the opposing lane disappear. The arrival-order choice is unsafe because an approaching vehicle already has a direct path. Parked cars are not the central right-of-way conflict described by this rule. Wait until the oncoming lane and pedestrian path are clear, then complete the turn. The practical cue is turning left means crossing traffic, so yield before crossing.
A driver outside the procession may not drive between the vehicles while the procession is moving, unless authorized by a police officer or operating an emergency vehicle. Cutting through breaks can separate the procession and create conflicts at intersections. Yielding, waiting, and staying outside the line are all consistent with respecting its right-of-way. The rule does not make the procession immune from reasonable care, but it does prohibit inserting an unrelated vehicle into the moving line. Spot the lead and following vehicles, slow down, and let the group pass together.
Traffic already circulating has priority over a vehicle that has not entered. Montana states that drivers entering a traffic circle or rotary must yield to drivers already in the circle. The entering driver still needs to approach at a safe speed and proceed only when the path is clear. Being first in line or traveling below 15 mph does not create priority. Look left before committing to the circle and watch for pedestrians at the crossing.
The vehicle coming from a lesser access point is entering an established roadway, so it must stop and yield to traffic already there. This requirement covers driveways, alleys, and roadside entrances. Accelerating through a gap is not a substitute for the required stop, and main-road drivers do not automatically yield. The shoulder is not a waiting lane. Scan both directions, stop where you can see, and enter only after the roadway is safe.
A right turn on red is conditional, not automatic. Montana permits it after the vehicle has stopped, is in the proper lane, and the driver has determined that proceeding is safe, unless a sign prohibits the turn. Failing to stop makes the movement unlawful even on an empty-looking corner. A wave from another motorist cannot replace the signal, sign, or safety checks. Look left, right, and ahead for traffic, bicyclists, and pedestrians.
Montana allows turning around on a roadway only where the driver has 500 feet of unobstructed view in both directions, almost two average city blocks, and no vehicles are approaching. One hundred feet of view ahead is not enough, and turning near a curve or hill is both illegal and dangerous. Whether police are nearby has nothing to do with the rule. Many city ordinances also ban U-turns in the middle of a block, and some ban them entirely.
Slow moving vehicles must drive in the extreme right lane, and when four or more vehicles are slowed behind one, it must turn off the roadway whenever there is enough room for a safe turnout. Two following vehicles do not trigger the rule, and no officer's order is needed. Farm tractors, animal drawn vehicles, and road maintenance vehicles usually travel 25 mph or less and carry a slow moving vehicle sign, but they have no general right of way over faster traffic.

Alcohol and DUI

Montana treats a BAC of 0.08% or more as enough for an arrest for driving with that alcohol concentration. The 0.02% figure belongs to drivers under 21, so it is not the general adult threshold. A reading of 0.16% is not needed before enforcement can begin, and 0.05% is below the stated adult threshold. On a test question, separate the ordinary adult number from the special under-21 rule before choosing.
An open alcoholic beverage container must be kept in a locked glove compartment or storage compartment, among the lawful storage locations listed by Montana. An unlocked cup holder, a door pocket, and a floor area in the passenger compartment leave the container accessible. The key detail is that the compartment must be locked, not merely covered or located away from the driver’s hand. Check the storage location before driving on a highway.
One alcoholic drink is 1.5 ounces of 80 proof liquor, one shot glass, straight or with a mixer; 12 ounces of commercial beer; or a 5 ounce glass of wine. The manual warns that microbrews and craft beers often contain more alcohol than a 12 ounce commercial beer, and specialty drinks can equal several normal drinks. The average person's body processes one drink in one hour, yet alcohol can still accumulate at that rate. The manual's best answer is simple: if you drink alcohol, do not drive.
In Montana, 50 percent of all traffic fatalities are alcohol related, and over 2,100 injuries are the result of a drinking or drunk driver; nationally over 23,000 deaths occur yearly as a direct result of a drinking or drunk driver. The Report A Drunk Driver program, started in 1981, lets anyone call 1-800-525-5555 toll free to report a suspected impaired driver with a description of the vehicle and its direction of travel.
Current statistics show that law enforcement officials are able to make contact with 37 percent of those suspected of driving under the influence, and of those contacted, 71 percent are arrested for drunk driving. Two drinking drivers are arrested each day in Montana as a direct result of the program. If you suspect someone is driving while intoxicated, call toll free 1-800-525-5555 with a description of the vehicle and its direction of travel.
Montana's manual is direct: if a police officer asks you to take a test, you must do so, and you can lose your driver license if you refuse a BAC test. Treating the test as voluntary is the mistake that costs drivers their license. There is no warning only exception for refusals without a crash, and a refusal does not force the officer to let the driver go. The test is usually a breath, blood, or urine test that measures blood alcohol concentration.
A first alcohol conviction in Montana brings a license suspension of six months, along with a fine and possible jail time. Thirty days and three months are too short, and two years exaggerates the first offense suspension. The manual warns that second and later convictions carry much worse penalties, and it separately says a driver can lose the license for refusing a BAC test when an officer asks. A driver under 21 can be arrested at a BAC of just 0.02.
Montana generally bans open alcoholic beverage containers in the passenger area, but the law has exceptions, including passengers carried by a hired driver in a bus, taxi, or limousine. A family car's back seat is still the passenger area, so an open beer there is an offense. A cup holder is within the driver's reach, and stopping at a red light changes nothing. The glove compartment choice fails because the manual allows only a locked glove or storage compartment.
For vehicles without a trunk, Montana allows an open alcoholic beverage container behind the last upright seat or inside a closed container kept in an area the driver and passengers do not normally occupy. A locked glove or storage compartment is also allowed. Putting the cap back on does not make the container unopened, and the front seat, the center console, and the space under the driver's seat are all within the passenger area where an open container is an offense.
Citizens who suspect someone of driving while intoxicated are asked to call local law enforcement or the Montana Highway Patrol and describe the vehicle and the direction it is traveling. The caller does not have to give a name, so the choice demanding the caller's personal details is wrong. Nobody expects a caller to know the other driver's name or BAC, and photographing a driver while you are driving adds a dangerous distraction. The toll free number is 1-800-525-5555.

Signals and markings

Roadway lines and symbols divide lanes, show when passing or changing lanes may be allowed, identify turn lanes, define pedestrian walkways, and mark where a driver must stop for a sign or signal. They do not make every line crossable or turn a shoulder into a travel lane. Read the marking together with the sign, signal, and traffic around you. A painted line provides guidance, but a lane change still requires a safe opportunity.
A steady yellow signal means caution and warns that the light is about to turn red. Enter only if stopping safely is no longer practical. It does not grant unrestricted priority, require backing up, or invite acceleration. The useful decision is based on stopping distance: if you can stop safely, do so; if you are already too close, clear the intersection carefully without creating a new conflict.
Flashing railroad crossing lights mean a train is coming, so the driver must always stop when the lights begin to flash. If the crossing has more than one track, the manual says to make sure all tracks are clear before starting to cross. A driver may not race a gate, drive around it, or treat an unseen train as permission to continue. Where gates are used, remain stopped until the gates are raised and the lights stop flashing.
A dark or malfunctioning signal removes the normal light cycle, so Montana drivers should stop as though every approach has a stop sign. The driver who stops first generally proceeds first, but that courtesy does not remove the duty to check for hazards. The tempting idea is to continue because no light is displayed, yet an unregulated intersection can still contain cross traffic or pedestrians. Treat the location as an all way stop, make a full stop, scan carefully, and proceed only when safe.
Montana describes roundabouts as low speed circular intersections and directs drivers to travel at 15 mph or less. A driver should reduce speed before entry, look left for circulating traffic, and yield to vehicles already inside. The road’s approach speed does not automatically carry into the circle, so selecting the ordinary posted limit would be unsafe. The practical cue is the center island and curved path: slow before the yield line, keep control, and continue around until the desired exit.
A flashing yellow signal permits movement but calls for caution, and Montana notes that it usually means slowing down. It is not the same as a flashing red, which requires a complete stop. The driver still needs to scan for vehicles, pedestrians, and changing conditions before entering. The useful habit is to lift off the accelerator and cover the brake as the signal comes into view, then proceed only after confirming that the intersection can be crossed safely.
HOV stands for High Occupancy Vehicles, and it marks a lane reserved for vehicles with more than one person in them. Reserved lanes are marked by signs stating the special use, and often have a white diamond posted at the side of the road or painted on the road surface. The signs also say how many people must be in the vehicle and the days and hours the rule applies; HOV 3 means at least three people. It is not a shoulder, an emergency lane, or a motorcycle lane.
A steady yellow signal means caution and warns that the signal is about to turn red. Montana says not to enter against it unless your vehicle is already too close to stop safely. That exception is about avoiding an unsafe sudden stop, not permission to accelerate toward the intersection. A yellow light is also not a protected movement and does not excuse entering a blocked intersection. Check your distance, brake smoothly when stopping is safe, and never use the color as a reason to speed up.
A steady yellow signal warns that red is coming. Montana says not to enter against it unless the vehicle is already too close to stop safely. That narrow condition recognizes that an abrupt stop can itself create danger. A crowded road behind, a right turn, or the absence of a pedestrian signal does not authorize entry. As the light changes, check your distance and brake smoothly if stopping is safe. The yellow light should trigger caution and preparation, never a race to beat red.
A flashing yellow arrow allows the left turn but does not protect it from opposing road users. Oncoming traffic has a green light, and pedestrians may also be crossing, so the driver must judge whether a safe gap exists before moving. The immediate-turn choice mistakes a permissive indication for a protected one. Waiting for red is unnecessary and may create confusion, while yielding only to stopped vehicles ignores moving traffic and people in the crossing. Associate the flashing yellow arrow with permission plus a careful yield check.
Montana treats a nonworking signal as a stop-controlled intersection in every direction. Drivers should stop, observe the other approaches, and proceed carefully according to who arrived first while confirming that movement is safe. Continuing through assumes the dark signal removes control, which creates a serious collision risk. Looking only left misses traffic and pedestrians from other directions. Police presence is not required for the intersection to function. The cue is a dark or malfunctioning signal: make a full stop and treat each approach as controlled by a stop sign.
Montana's passing rule assigns a clear purpose on multi-lane roads: the left-most lane is intended for passing slower vehicles. That does not remove the duty to pass safely or to signal and observe surrounding traffic. The lane nearest the right shoulder is a travel lane, and passing on the right is legal only in limited situations, while choosing any lane ignores the manual's lane-use guidance. A center lane may be appropriate for through travel, but it is not automatically the passing lane. Look for the left-most lane when planning a lawful pass.
At a steady red signal, Montana lets you cautiously turn right after stopping when entering a two-way street. You may make the turn unless a sign or police officer tells you not to turn against the red light, and you must yield to pedestrians, bicyclists, and traffic in the intersection. Turning before stopping skips the first requirement, a green arrow is not needed, and signaling alone does not create a safe gap.
A flashing red signal carries the same stopping requirement as a stop sign. The driver must make a complete stop, check left, right, and ahead, yield to traffic and pedestrians, and proceed only after the path is safe. A brief slowdown is not a complete stop, while waiting for green invents a requirement that applies to a different signal display. A green arrow grants a protected movement and has the opposite meaning. The visual cue is red flashing still begins with a full stop, even though the light is not steady.
A dashed yellow centerline separates traffic moving in opposite directions and may be crossed to pass when the driver has a safe opportunity. The marking does not promise that every pass is safe, so a following vehicle's impatience is not a reason to go. Passing on the shoulder is specifically prohibited, and a centerline never removes the need to check for oncoming traffic, hills, curves, or other hazards. The helpful visual rule is yellow separates opposing traffic, while dashed means the crossing may be allowed under safe conditions.
A paired solid and dashed yellow centerline assigns the restriction by side. A driver beside the solid line may not cross it to pass, while traffic beside the dashed line may pass when safe. The presence of a dashed line on the opposite side does not authorize both directions. The shoulder is not a legal passing lane, and the rule is about overtaking, not a blanket ban on every left turn. Identify the line immediately next to your vehicle before deciding. Solid on your side means stay behind until a lawful opportunity appears.
The stopping location follows a clear order. Stop before the pavement stop line when one exists. If there is no line, stop before entering the nearest crosswalk. If there is no crosswalk, stop before entering the intersection. Rolling past the crosswalk can put the vehicle in a pedestrian's path, while a signal pole is not the prescribed reference point. The curb option makes stopping depend on pedestrians when the red signal applies regardless. Scan for the first applicable boundary and keep the vehicle behind it.
The flashing DON'T WALK display tells a person who has not started to wait, but it does not strand someone already in the crosswalk. That pedestrian should continue crossing the street and clear the roadway. Turning back can prolong exposure to traffic, and stopping in a lane creates an avoidable obstruction. Beginning another crossing is unrelated to the signal's instruction. Drivers should remain alert for people finishing their crossing. The visual cue is location matters: at the curb, wait; already in the crosswalk, finish safely.
The manual identifies an upheld orange hand as a DON'T WALK indication. A person at the curb should wait for a WALK signal before starting. The display does not promise a safe crossing, authorize an unexamined walk, or direct anyone to stop at a median. Running is especially poor guidance because it reduces observation and control. Drivers should still watch for pedestrians who are already finishing a crossing. Remember the symbol's basic message: an orange hand is a hold signal, not an invitation to enter the street.
Reversible lanes change direction at different times, so drivers must read the overhead indication before entering. Montana describes a green arrow as permission to use the lane beneath it. A bus reservation is a separate control, and a changing-lane warning uses a steady yellow X. A red X closes the lane, so it is not interchangeable with the green arrow. Check the display again if conditions or lane controls change.
Two solid yellow lines separate opposing traffic where passing is restricted for both directions. Montana permits crossing a solid yellow line for a left-turn maneuver, and its lane-marking guidance also allows a safe turn into certain lots, driveways, or roadways. That exception is not permission to overtake. Good visibility and a horn do not change the marking. Read the entire lane pattern before deciding whether a turn, rather than a pass, is allowed.
The side of the paired yellow lines matters. Montana allows a driver to pass when the dashed line is on that driver's side, but only if the movement is safe. A solid line on your own side would prohibit passing, while darkness does not create an exception. Even with the dashed marking, check sight distance, oncoming traffic, and the space needed to return before moving left.
White lines divide lanes moving in the same direction, and a solid white line signals that changing lanes should generally be avoided. The manual leaves room for a special situation, so it is not an absolute ban. A centerline is yellow, not white, and stopping on a lane boundary creates a needless obstruction. Continue steadily, check mirrors and blind spots, and move only when the situation genuinely calls for it.
The shared center lane is a two-way turning space, not a travel lane for overtaking or cruising. Montana reserves it for left turns and for U-turns where those turns are permitted. The alternating arrows show that drivers from both directions may use the lane, so enter carefully and yield to an opposing user already there. Do not treat the center lane as a shortcut for straight travel or as temporary parking.
A steady green arrow assigns a protected turning movement, which is different from an ordinary green light. Montana still expects drivers to proceed cautiously and watch the intersection. The arrow does not erase awareness of pedestrians or other hazards, and a red transition warning is described separately for yellow signals. Do not reverse direction because of the arrow. Enter only when the intended path is clear and complete the turn as directed.

Parking

A vehicle parked on a roadway must be within 18 inches, or 1.5 feet, of the curb or shoulder. One foot is closer than the required maximum but is not the stated rule, and three feet leaves the vehicle too far into the roadway. The visual cue is simple: park close enough that the vehicle does not interfere with moving traffic while staying beside the curb or shoulder.
Montana prohibits parking within 15 feet of a fire hydrant, so firefighters can reach it without a car in the way. Five feet is far too close. The 30 foot distance applies to a traffic signal, stop sign, or yield sign, and 50 feet applies to a railroad crossing, so those figures belong to other no parking rules. A vehicle parked at the curb must also be within 18 inches of it.
Montana bars parking within 30 feet of a traffic signal, stop sign, or yield sign, because a parked car there can hide the sign from approaching drivers. Fifteen feet is the fire hydrant rule, 20 feet is the rule for a crosswalk or sidewalk at an intersection, and 50 feet is the railroad crossing rule. Mixing up these distances is a common test mistake, so learn each one together with the object it protects.
Parking is prohibited within 50 feet of a railroad crossing in Montana. That space keeps parked vehicles from blocking the view of trains and from crowding the tracks. Fifteen feet is the fire hydrant distance and 30 feet is the distance for a traffic signal, stop sign, or yield sign, so both are too close here. The no parking list does not use 100 feet for anything. Parking on the railroad tracks themselves is also forbidden.
Montana prohibits parking within 20 feet of a fire station driveway on the same side of the street, or within 75 feet of the driveway when parking on the opposite side. The larger distance across the street gives fire trucks room to swing out. A single 15 or 30 foot rule for both sides is wrong, and 50 and 100 feet are not the distances in the manual. Never block any driveway, alley, or lowered curb either.

Safe driving

The Montana manual says to keep your windshield clear so you can focus on the road ahead. Damaged glass blocks your view of the road and can break more easily in a minor collision or when something hits the windshield, so the manual says to have the windshield replaced if the glass is damaged. Covering the damage, driving slowly, or switching on high beams does nothing to restore the glass or clear your view.
Snow and ice must be removed from all windows before driving so the driver has a clear view of the road. Cleaning only the driver’s side still leaves important blind areas, and a defroster used while moving delays the required visibility check. A partially cleared windshield is not enough. Before releasing the brake, clear every window and make sure the wipers can handle moisture that remains. This check also helps reveal pedestrians, cyclists, lane markings, and vehicles approaching from either side.
Montana’s manual calls for a proper turn signal 300 feet before turning on rural roads. The 100 foot distance applies in town, so it is the tempting but incorrect shorter figure. Signaling early gives following and approaching road users more time to understand your plan. Use the road setting to select the distance: 100 feet in town and 300 feet on rural roads.
The manual recommends slowing down and preparing to stop when an animal is seen. A sharp swerve can send the vehicle into oncoming traffic or a ditch, and acceleration does not make an unpredictable animal safer. Continuous horn use with unchanged speed ignores the need to create time and space. If stopping or avoiding is impossible, keeping control is safer than making a sudden steering move.
The deer-crossing warning tells drivers that deer often use the area, so alertness and reduced speed are the appropriate response. Speeding narrows reaction time, and a sharp turn can create a collision with another vehicle or a roadside object. Waiting for another car to appear misses the hazard entirely. Scan beyond the first animal too, because wildlife may travel together.
On a two-lane road, Montana permits crossing left of the centerline for overtaking and passing another vehicle when the maneuver can be done safely. A rough shoulder, a hill, or an empty view behind does not create permission by itself. The driver must still evaluate oncoming traffic, sight distance, markings, and the space needed to return right. Passing is a planned maneuver, not a general lane preference.
A truck, bus, van, or vehicle pulling a camper or trailer may not be able to see a vehicle directly behind it. It could stop suddenly without knowing the following driver is there. Falling back provides more room to see ahead and react. The manual does not give the larger vehicle automatic priority in every situation, and it does not set a universal one-car-length rule. Extra space is a visibility and stopping buffer.
Animals can be frightened by motor vehicles, so the manual directs drivers to slow down and stop when an animal or horse-drawn vehicle approaches or crosses the vehicle's path. Honking or passing closely may startle it, while steering toward it creates danger. Allow the animal to pass, leave room when traveling in the same direction, and continue only after the path is safe.
When an animal is near the roadway, slow down and be prepared to stop. If there is not enough time to stop or avoid it, do not swerve sharply. The manual explains that a driver's chance of serious injury is lower when the driver hits the animal and avoids swerving into oncoming traffic or rolling the vehicle over in the ditch. Deer, elk, and similar wildlife travel in herds, so seeing one animal is a cue to look for more, especially around sunrise and sunset.
Montana applies the seatbelt requirement to every occupant while this restricted license is active. The driver cannot treat the rule as a personal requirement only, so the choice “Only the teenage driver must buckle up” leaves passengers outside the rule. The nighttime option confuses seatbelt use with the separate restricted-license driving-hours limit. A back-seat exception is not provided either. Before moving, the driver should check that each person is buckled in a properly adjusted belt. This is a trip-by-trip obligation, not something that changes with distance, daylight, or whether the road appears busy.
A sudden flat tire calls for a firm steering grip and a straight path while speed is reduced gradually. Hard braking or a sharp turn can destabilize the vehicle, which is why the option “Brake hard and turn sharply toward the shoulder” is unsafe. Releasing the wheel gives up directional control, and stopping in the lane creates a collision hazard. Take your foot off the accelerator, use the brakes lightly, and move off the road only after control is established.
Montana requires a driver to stop when meeting or passing a stopped school bus from either direction while its red lights flash, at least 30 feet from the bus. The rule does not depend on seeing children, hearing a horn, or being behind the bus. The directional wording is the key cue: traffic approaching from either side must respond. The driver cannot proceed until the red lights are turned off. The exceptions are a bus on a different road or one stopped in an adjacent loading zone where pedestrians may not cross.
The slippery-when-wet warning identifies pavement that becomes unusually slick after rain. The safe response is to reduce speed, avoid hard braking or sudden direction changes, and leave more space ahead. It does not reserve the lane, encourage aggressive braking, or announce a closure. A useful cue is to make every steering and braking input gradual as soon as the road surface is wet.
At an uncontrolled intersection, the driver should remove the foot from the accelerator, cover the brake, scan left, right, and left again, and prepare to yield. Maintaining speed ignores hidden hazards, while stopping every time overstates the rule. Limiting attention to the left misses traffic from the other direction and pedestrians. The repeated scan is the practical cue before crossing or turning through the intersection.
A teenager's highest lifetime crash risk is in the first months of solo driving and the first 1,000 miles, which is why Montana's first-year restricted license limits night driving and passengers. The manual notes that fatal crashes are more likely at night for all ages, but the risk is highest for teenagers. Once the teen reaches Step 3, the license confers full privileges. Five years of experience and age 25 are not the peak the manual names.
Montana requires headlights when insufficient light makes people or vehicles invisible at a distance of 500 feet. The rule is tied to what the driver can see, not to a particular travel speed, another driver's signal, or a parked vehicle. Check visibility at dusk, in darkness, and in conditions such as dust or fog. Turn the lights on early enough for others to see your vehicle too.
The Three-Second Rule uses time rather than a fixed number of car lengths. Watch the vehicle ahead pass a stationary object, then count until your vehicle reaches that same point. Arriving before the count is complete means the gap is too short, so drop back and check again. The method works at any speed and gives a practical cue when traffic flow changes.
The manual says that when heavy rain, a snowstorm, or thick fog limits visibility to about 200 feet, a driver cannot safely travel faster than 30 mph. Headlights improve visibility to others but do not make an unsafe speed acceptable. The posted limit and a high-speed escape strategy ignore sight distance. If the downpour prevents safe driving at all, pull off in a safe place and wait for conditions to improve.
The Three Second Rule uses time rather than a fixed number of car lengths, so it works at any speed. Watch the vehicle ahead pass a stationary object, then count until your vehicle reaches that same point. Reaching it before finishing the count means the gap is too short. A fixed car length ignores speed, and two seconds or one second per ten miles per hour is not the three second baseline. The manual says a four second distance may be needed on slippery roads, when following motorcycles, or when it is hard to see.
Montana does not use one standard speed limit for every construction or work zone. The Department of Transportation, a local authority, a utility company, or a private contractor sets a speed specific to that zone. Drivers must read the posted limit and obey it, even if the surrounding road normally permits faster travel. Assuming a universal 25 mph rule misses the local posting, while choosing the normal highway speed ignores the temporary control. Orange devices and work activity should prompt an early speed check.
When water separates the tires from the pavement, lifting your foot from the accelerator helps the vehicle slow without adding a sudden braking or steering demand. The manual also advises keeping the wheel straight and postponing a stop or turn until the tires grip again. Hard braking while turning can worsen the loss of control, and acceleration keeps the tires moving across the water film. Use the sensation of a light or unresponsive steering wheel as your cue to ease off the gas and wait for traction to return.
In a 30 mph crash, a 100 pound adult becomes a 3,000 pound force against the child, which is why the manual warns that holding a child while riding could crush the child during a crash. It also says never to place a rear-facing car seat in the front passenger seat with an active air bag, and that whenever possible children under age 13 should be secured in the backseat. Every occupant must be belted under Montana law.
Many bicyclists ride further into the lane, approximately 18 to 24 inches, to discourage motorists from attempting a dangerous in lane pass. A rider that far out is not being rude; the position keeps cars from squeezing by. Change lanes to pass when possible, and remember bicycle spoke reflectors must sit within 3 inches of the rim so drivers can see them at night.
Driving requires decision making and critical thinking, and 90 percent of driving decisions are based on what we see. That is why Montana requires a vision test before issuing a license, measuring at least 20/40 vision in at least one eye, with or without corrective lenses. The manual also recommends having your eyes checked regularly. Keep windows and lights clean so you can see and be seen, because 50, 25 and 10 percent understate the figure.
Crashes involving direct hits or swerving to avoid an animal result in about 200 deaths and 26,000 injuries per year according to the Centers for Disease Control and Prevention. Large animals such as deer, bear, moose, horses, elk and cattle were involved in many of these crashes. Look for animals especially at sunrise and sunset, slow down when you see one, and if there is no time to stop, do not swerve sharply into oncoming traffic or the ditch.
With good tires and brakes on dry pavement, at 50 mph it can take about 400 feet to react to something you see and bring the vehicle to a stop, about the length of a city block. At 30 mph it can take about 200 feet. The 1,600 foot figure appears elsewhere in the manual as the clear distance needed to pass at 55 mph, not a stopping distance. It takes much longer and farther to stop than many people think.
Mirrors cannot show every area beside and behind a vehicle. Montana tells drivers to look over the shoulder in the direction of movement because the rear corners are blind spots. Mirror-only scanning can miss a motorcycle or car positioned outside the reflected view. Ignoring traffic behind removes a crucial safety check, and hazard flashers do not communicate which lane you intend to enter. Signal, inspect the mirrors, then make a quick shoulder check immediately before moving so the decision reflects current traffic.
Hydroplaning occurs when speed on a wet roadway causes tires to float on a film of water rather than maintain normal contact with the pavement. That loss of traction can make steering feel ineffective and can become complete in heavy rain, especially with worn tires. A puncture, overheating, or deliberate braking technique describes a different problem. The strongest prevention cue is speed: slow down in rain or whenever the road is wet, then avoid abrupt steering and braking if traction begins to disappear.
Montana advises drivers not to share a lane with a pedestrian or bicyclist. The driver should wait until it is safe to pass in the adjoining lane, leaving the cyclist room instead of squeezing past within the same lane. A shoulder is not a shortcut around the safety check, and a horn does not make an immediate pass lawful or safe. Look for traffic approaching from behind and ahead, signal as needed, and complete the pass only when the neighboring lane provides enough space.
Montana's guidance connects speed to actual road and weather conditions, not merely to the number on the sign. Wet pavement, snow, and ice reduce traction and lengthen the distance needed to stop, so the driver should slow progressively and leave more room ahead. Waiting for a slide means waiting until control has already been lost. The posted-limit choice ignores the manual's warning that limits assume ideal conditions. Driving on the shoulder is neither a substitute for a safe speed nor a normal travel option. A simple cue is less grip means less speed and more cushion.
At 55 mph you travel over 800 feet in the roughly 10 seconds a pass takes, and so does an oncoming vehicle. That means you need over 1,600 feet, about one third of a mile, of clear road to pass safely. It is hard to judge the speed of oncoming vehicles at that distance, so if you are not sure, wait. You should also not start to pass within one third of a mile of a hill or a curve, because your view of oncoming traffic is blocked.
The Three-Second Rule is a time-based check that works at any speed. Watch the vehicle ahead pass a fixed object, count one-one-thousand through three-one-thousand, and make sure your vehicle does not reach that object before the count ends. One second leaves too little reaction and braking time. Vehicle lengths change with car size and speed, so they are not the manual's measure. Ten seconds is associated with passing at 55 mph, not ordinary following. Pick a sign or pole and count rather than guessing by appearance.
A motorcycle can fall suddenly, and the rider needs room that a following driver may not need behind an ordinary vehicle. Montana identifies following motorcycles as a situation that can require a four-second following distance, especially when pavement is wet or icy, roads are gravel, or surfaces are metal. One second sharply reduces recovery time. Cutting space on slippery pavement reverses the safety response. A fixed distance ignores speed and surface conditions. Use a landmark and count four seconds when the motorcycle passes it, then increase space if visibility or traction deteriorates.
When a driver is being followed too closely and a right lane is available, Montana advises moving over to the right. If no right lane exists, the driver should wait for a clear opportunity and reduce speed slowly. Sudden braking can cause a rear-end crash, while acceleration may encourage continued aggressive driving. Straddling the centerline creates a separate lane-position hazard and is not a defensive response. The goal is to create room and let the impatient vehicle pass safely. Check mirrors, signal, and move only when the lane is clear.
Montana's Split the Difference Rule says to steer a middle course between two hazards, such as oncoming and parked vehicles. However, if one is more dangerous than the other, leave a little more space on the danger side. The manual's own example is an oncoming tractor-trailer: leave a little more room on the side that the truck will pass. Moving toward the truck reduces that cushion, the shoulder is not a travel path, and rigidly equal spacing ignores the greater danger.
Aging affects vision, hearing and reaction time, which is one reason the accident rate of drivers 65 and over, in terms of miles traveled, is exceeded only by the rate of drivers under 24 years old. Frequently reported errors by older drivers include inattention, failure to drive in the proper lane, failure to signal or observe stop signs and signals, and unreasonably slow driving on busy highways. The manual suggests getting your doctor's advice about driving.
The manual asks drivers not to make a difficult situation worse. If another motorist needs to change lanes suddenly, slowing down and allowing the merge can keep traffic moving and reduce the chance of contact. Closing the gap removes the escape space the other driver needs. A continuous horn does not solve the lane conflict, and moving into the other lane creates an intentional collision risk. Scan ahead for confused or struggling drivers, lift off the accelerator early, and preserve a usable gap. Courtesy here is a concrete collision-avoidance tool.
A horse can react unpredictably to noise and a close vehicle. Montana requires due care, including a reasonable speed and a reasonable distance, and makes sounding the horn when approaching or passing a horse illegal. The honking option directly violates that instruction. A posted limit may still be too fast for the animal and surroundings, so it does not replace a reasonable speed. Revving adds noise and can frighten the horse. Ease off early, give the animal room, and wait if the rider signals you to stop.
During a skid, the tires have lost their normal grip, so abrupt braking can worsen the slide. Montana says to stay off the brake, remove your foot from the accelerator, look where you want to go, and steer in that direction. Holding the wheel while accelerating does not address the slide, and locked tires reduce control. Once the vehicle starts to straighten, correct back so it does not swing into another skid.
A recent AAA Foundation for Traffic Safety study showed 13 percent of crashes in which a person was hospitalized and 21 percent of crashes in which a person was killed involved a drowsy driver. The manual adds that after being awake for 18 hours straight, driving skills resemble those of an impaired driver. It advises taking breaks every two hours or so, walking around and getting fresh air, and not planning to drive late when you are normally asleep.
Heatstroke begins when the core body temperature reaches about 104 degrees and the body's cooling system is overwhelmed, and a core temperature of about 107 degrees is lethal. The manual quotes NHTSA that vehicle heatstroke occurs when a child is left in a hot vehicle and the child's temperature rises in a quick and deadly manner. Even great parents can forget a child in the back seat, especially when a routine suddenly changes, so check the back seat before walking away.
A driver must stop no less than 15 feet from the nearest rail when warning signals, crossing gates, stop signs, or human watchmen show a train is coming, and also when the train is within 1,500 feet of the crossing or is clearly visible and an obvious hazard. Waiting for a gate or a horn ignores that second trigger. Five hundred feet is far too close for the rule. Never try to beat a train across the tracks.
Texting combines manual, visual, and cognitive distraction, which is why the manual calls it the most alarming distraction. Sending or reading a text takes your eyes off the road for 5 seconds, and at 55 mph that is like driving the length of an entire football field blindfolded. One or two seconds understates the time, and 10 seconds and a mile overstate it. Pull over and stop before handling a phone.

Road signs

The STOP sign is identified by its eight-sided shape, which makes it recognizable even when visibility is poor. A round sign belongs to the railroad-crossing warning category, while a five-sided shape is associated with school-related warnings in standard sign systems. A rectangle describes many regulatory or guide signs, not the unique STOP outline. Shape recognition helps a driver respond before every word is readable.
Regulatory signs generally use a rectangular format with black words or symbols on a white background, and drivers must obey the rules they present. Diamond yellow signs warn about conditions ahead rather than state ordinary regulations. Round red signs and pentagonal green signs are not the general pattern described for Montana regulatory signs. Color and outline work together, so use both clues when identifying an unfamiliar sign.
Yellow diamond signs are warning devices for dangerous conditions ahead, so the driver should approach with great caution. They do not usually impose a speed limit, advertise services, or require every vehicle to stop at the sign. Those functions belong to other sign categories. The useful cue is the combination of yellow, diamond, and warning language: expect a hazard and adjust attention and speed.
School speed limit signs identify a posted speed or a reduced speed authorized by the local authority. Montana therefore does not use one universal number for every school location. The 25 mph and 5 mph choices invent fixed statewide limits, while the no-change choice ignores the signs, markings, and flashing lights that signal a change. Read the roadside devices at each school zone and adjust accordingly.
A STOP sign requires a complete stop before the intersection, followed by a careful yield to traffic close enough to create an immediate hazard. The open-looking lane in the choice “Reduce speed but continue if the lane looks open” is not enough to waive the stop. Waiting for another vehicle would reverse the rule, and yielding without stopping describes a yield sign rather than this octagonal sign. If a crosswalk is present, the stop occurs before entering it. The practical cue is the distinctive eight-sided shape, which remains recognizable even when poor visibility hides much of the sign face.
A YIELD sign calls for a reasonable reduction in speed and a yield to every vehicle on the roadway being entered. It does not impose the automatic full stop that a STOP sign requires, although stopping may still be necessary when traffic requires it. Accelerating to assert priority is especially unsafe because the sign assigns priority elsewhere. Proceeding without checking turns the sign upside down: yielding means giving way, not receiving preference. Scan the roadway, judge the gap, and stop if that is needed to let traffic proceed safely.
The square DO NOT ENTER sign warns that the road ahead is a one-way roadway in the direction opposite the driver, or that vehicles are not permitted there at all. It is not a turn restriction limited to right turns, and it does not identify a parking area. Yielding to pedestrians cannot authorize entry where the sign prohibits vehicular movement. The useful driving cue is to stop the intended entry and find the permitted route instead of trying to use an empty lane or a brief gap in traffic.
The Montana manual groups several urgent meanings under the color red on intersection traffic control signs: red always means stop, yield, do not enter, or wrong way. The STOP, YIELD, and DO NOT ENTER signs all use red for that reason. Service information, recommended speeds, scenic routes, and passing zones are not red sign meanings in the manual. Treat a red sign as an immediate instruction to stop, yield, or avoid the prohibited movement.
The NO U TURN sign prohibits turning about so the vehicle travels in the opposite direction at that intersection. It does not ban ordinary passing, a right turn, or proceeding straight. A driver who needs to reverse direction must wait for a location where the maneuver is legal, visible, and safe. Do not interpret the curved arrow as a general turn restriction: the defining feature is that the maneuver reverses the vehicle's direction. Check for additional lane controls before choosing another turn.
The NO LEFT TURN sign bars a left turn at the intersection. It does not prohibit a right turn or straight travel unless another sign or signal says so. Changing lanes after the intersection is a separate maneuver and is not what the red slash over the left-turn arrow addresses. Drivers should select a permitted movement, continue without turning left, and look for a later legal route. The arrow symbol matters: the restriction follows the pictured movement, not every possible movement through the intersection.
A red circle and slash over an arrow means the pictured action is prohibited, so this sign rules out the right turn. It does not make the turn mandatory, give the turning driver priority, or create a special acceleration requirement. The driver should continue with a permitted movement and obey any separate signal or lane instruction. Reading the symbol literally is the key: the slash changes the arrow from an available movement into one that must not be made at that location.
The number on a SPEED LIMIT sign sets the maximum speed from that sign until another speed sign changes it. It is not a minimum, a passing-only suggestion, or a nighttime-only permission. Road, weather, visibility, and traffic conditions can still require a driver to travel below the posted maximum. Treat the displayed number as an upper boundary, then choose a safe speed for the actual conditions. A later sign, rather than a driveway or intersection, is what ends that posted limit.
KEEP RIGHT directs traffic to the right side of an obstruction. The left-side choice reverses the instruction, while stopping for a flagger is not the message of this sign unless a separate work-zone control requires it. Staying on pavement alone does not make either side acceptable, so the choice “Use either side as long as the vehicle stays on pavement” ignores the required direction. Reduce speed, watch for other vehicles and workers, and pass the obstruction on its right as the sign indicates. A divider, island, or work-area object may be the reason for the restriction.
The railroad crossbuck identifies a public railroad crossing, and a supplementary sign below it can show how many tracks cross the roadway. The sign is not limited to private driveways or school areas, and it does not wait for a train to pass before applying. A driver should approach prepared to stop if a train is coming, while checking every track represented at the crossing. The extra track count matters because a clear first track does not necessarily mean the entire crossing is clear.
This round warning sign announces a railroad crossing ahead, so the driver should reduce speed, look and listen, and remain ready to stop. The manual says advance warning signs are located in advance of the crossings for exactly that purpose. Racing toward the tracks defeats the warning, turning around is not required, and stopping on the tracks creates a serious hazard. At the crossing itself, a crossbuck marks the public crossing, and a sign below it shows the number of tracks when there is more than one.
The five-sided School Crossing sign marks the point where school children cross the roadway, and the Montana manual says you must stop if pedestrians are waiting to cross. Waiting pedestrians are enough; a child does not have to be in the lane first, and a crossing guard does not have to be present. Honking does not give you the right to continue, and passing around waiting children puts them at risk. Slow down as you approach so you can stop smoothly.
A pedestrian crossing warning asks the driver to be alert for people crossing the path, slow down, and be ready to stop. Honking continuously can startle people and does not replace careful observation. The sign does not give vehicles priority over pedestrians, and using the shoulder to evade a crossing person is dangerous and improper. Scan both sides of the roadway, cover the brake, and yield when a pedestrian is in or entering the crossing area. The warning is about anticipating movement, not waiting until a person is directly in front of the car.
Montana uses traffic signals to control both vehicle drivers and pedestrians at some intersections and midblock crosswalks. Signals promote better movement of traffic on busy roads by assigning right of way. They are not limited to pedestrians or to major highways, and they are not the same thing as workers directing traffic in a construction zone. Watch the signal as you approach, and remember that pedestrians follow pedestrian signals when those are present.
STOP AHEAD is advance notice of a stop sign, so the driver should begin slowing and prepare for the required stop at the upcoming intersection. The warning sign itself is not the stop location, making an immediate stop beside it unnecessary unless conditions demand one. Accelerating to beat other traffic undermines the warning, and cross traffic does not determine whether the stop sign must be obeyed. Ease off the accelerator, identify the stop line or crosswalk, and arrive with enough control to stop completely before entering the intersection.
Work zones may use large flashing or sequencing arrow panels during the day or night to guide drivers into certain traffic lanes and show that part of the road ahead is closed. This supports an early, controlled lane adjustment while watching cones, barricades, workers, and nearby traffic. The panel does not guarantee that the current lane stays open, authorize passing, or cancel other work-zone controls. Follow the displayed direction and merge when it is safe.
The Divided Highway Ends sign warns that the highway ahead becomes a single roadway with traffic going in both directions, and the manual tells you to keep to the right. That is the opposite of a divided highway beginning, where a median separates two one-way roadways. The sign does not require passing, and it does not authorize U-turns. Keep right, watch carefully for oncoming traffic, and pay attention to the centerline as the road configuration changes.
A divided highway begins when a median or divider separates the route into two distinct one-way roadways. The driver should keep right of that divider and avoid treating it as a place to cross or turn around. The choice “The divided roadway ends and opposing traffic will share one lane” describes the opposite change, while the remaining choices invent an intersection or a U-turn permission. Reduce speed if the roadway layout is changing, identify the correct side of the median, and follow lane markings as the separate directions develop.
The slippery-when-wet warning calls for a slower speed, gentle braking and steering, and more space behind the vehicle ahead. Hard braking or sudden direction changes can reduce control on unusually slick pavement. Following closely makes spray and stopping problems worse, while maintaining speed with quick corrections ignores the warning. Ease off the accelerator before the wet section, increase the gap, and make smooth inputs. The sign describes a condition that may not be obvious until rain reaches the pavement, so prepare before traction is lost.
This warning announces a right curve ahead. A supplemental panel may show a suggested safe speed for negotiating that curve, but the arrow does not require a turn at an intersection. It also does not identify a detour or change the roadway to one-way travel. Reduce speed before entering the bend, keep the vehicle under control through it, and follow any posted advisory. The sign is advance notice of a changing alignment, so waiting until the steering wheel is already turning leaves less room to respond.
The sharp-right-turn warning sign tells you that the roadway turns sharply right ahead. It is not an intersection sign, so the four-way choice would send your attention to crossing traffic that the symbol does not promise. It also does not announce one-way travel or a railroad crossing. Reduce speed before the turn, scan for opposing traffic, and keep the vehicle under control through the bend.
The winding-road sign warns of a series of turns or curves rather than one isolated bend. The narrow-bridge choice describes a different warning, while loose gravel concerns the road surface and a steep hill concerns grade. Treat the sign as advance notice that the roadway keeps changing direction. Slow before entering the sequence, then maintain a speed that lets you steer smoothly around each curve.
The crossroad sign announces a four-way intersection and warns you to watch for traffic entering from the sides. A prohibition sign would carry a required action, and a school bus stop has its own warning symbol. The divided-highway choice describes a change in roadway separation, not crossing traffic. Ease off the accelerator, check both sides, and be ready to yield as you approach the intersection.
A no-passing warning marks an area where passing is prohibited, so a driver must not pass a vehicle moving in the same direction. The shoulder is not a substitute passing lane, and an empty view ahead does not cancel the restriction. The choice “Resume passing immediately because the zone has ended” reverses the meaning of the sign. Stay behind the vehicle, maintain a safe gap, and wait for a lawful passing opportunity after the restricted area.
The octagonal shape identifies a STOP sign, and the required action is a complete stop before entering the intersection. If a crosswalk is present, the stop must occur before entering that crosswalk. After stopping, the driver yields to traffic close enough to be an immediate hazard. Merely slowing is the rule associated with a yield sign, not this shape. Use the eight sides as the quick visual cue, then stop at the line or at the proper point before the crossing.
Black and yellow warning signs alert drivers to dangerous conditions ahead where extra caution is required. Their usual diamond shape reinforces the warning function, although the railroad crossing warning sign is a special round example. These signs do not set a speed limit by themselves, and they are not guide signs for services. When one appears, scan farther ahead, reduce speed as needed, and prepare for the specific condition shown, such as a curve, school, crossing, or narrowing roadway.
A red circle and slash is a prohibition marker. Montana explains that the driver must not do whatever the black arrow or symbol depicts. The sign does not recommend the movement, reserve the road for it, or identify a service. Read the underlying symbol first, then apply the slash to that action. For example, a crossed U turn symbol means do not turn around there. The quick visual cue is red around the symbol with a diagonal bar: the pictured maneuver is forbidden.
Warning signs are usually diamond shaped, and they alert drivers to dangerous conditions that require great caution. The octagon is reserved for STOP, while rectangles commonly carry regulatory or guide information. A circle is a special warning shape used for the railroad crossing ahead sign, so it is not the usual pattern. When a yellow diamond appears, look for the hazard it represents, adjust speed and position early, and expect conditions such as a curve, intersection, school, or narrowing roadway.
A STOP sign requires a complete stop before entering the intersection, and Montana adds that when there is a crosswalk, you stop before entering it. Stopping beyond the crosswalk can put the vehicle into a pedestrian path and reduces the driver's ability to yield safely. The center of the intersection and the far edge of the cross street are not stopping points. After stopping before the crosswalk, check for traffic close enough to be an immediate hazard before proceeding.
The number beneath this curve warning is guidance for handling the bend, not a new posted maximum. The manual describes it as a suggested safe speed, so a driver should consider that recommendation along with weather, pavement, traffic, and visibility. Choosing the legal-limit option is risky because a posted limit may still be too fast for a sharp turn or poor conditions. A useful cue is the sign's pairing: the diamond warns about the curve, while the small number helps you approach it conservatively. Slow before the bend and remain prepared to reduce speed further.
Montana warning signs use black and yellow to call attention to dangerous conditions ahead. Their usual diamond shape reinforces the warning function, although the railroad crossing ahead sign is an exception because it is round. The white and blue choice describes neither the manual's warning colors nor its typical shape. Orange and black belong more closely to work-zone devices, while green and white are commonly associated with guide information. When visibility is poor, look for both color and shape, then reduce speed and prepare for the hazard the sign announces.
The school crossing warning tells drivers that children may be using the roadway, so the manual directs them to slow down and watch for children at all times. A crossing guard is not required before the driver becomes cautious, and waiting for a child to enter the lane is too late. Honking does not replace observation or speed control. The safest mental marker is the combination of a school location and limited child visibility: reduce speed early, search both sides, and be ready to stop for a pedestrian.
Regulatory signs communicate obligations that govern how traffic must move. Montana describes them as signs showing the driver's maximum speed or another required action, and it directs drivers to obey the rules on all of them. A scenic route is guide information, while a curve warning identifies a hazard rather than a legal command. Treating the message as optional is especially dangerous because a regulatory sign can establish a speed ceiling or prohibit a movement. The visual cue is often a rectangular white sign with black words or symbols.
Most Montana warning signs are diamond shaped, but the railroad crossing ahead sign is specifically identified as round. That unusual shape is a recognition aid when a driver is scanning signs in poor visibility. School, winding-road, and sharp-turn warnings belong to the usual diamond-shaped warning group. The exception does not make the railroad message less urgent: it still announces a hazard ahead and calls for slower, attentive driving. Remember the pairing as a quick test cue: black and yellow warning family, round railroad exception.
When a train's approach is indicated by warning signals, gates, a stop sign, or a watchman, Montana requires a stop as close as practicable but at least 15 feet from the nearest rail. The rule creates a protected space for the vehicle and the crossing operation. Five feet is too close, 50 feet is not the stated universal distance, and merely clearing the tracks may leave the vehicle inside the required stopping zone. Treat active railroad warnings as a precise distance command, then wait until crossing is safe.
Warning signs alert drivers to conditions that may require a slower speed or extra attention. The manual characterizes them as black and yellow and says they warn of dangerous conditions ahead where great caution is required. A service facility belongs with guide information, and a route designation does not describe the warning class. Treat the sign as an advance cue to scan the roadway and prepare before reaching the hazard.
Regulatory signs communicate a rule that controls speed or another required action. Montana describes this category as rectangular with black words or symbols on a white background and says drivers must obey the rules shown. Recreation information is a guide function, weather hazards are warnings, and the railroad crossing warning has its own sign treatment. When you see a regulatory sign, adjust before reaching it and follow the posted instruction rather than treating it as a suggestion.
Orange identifies the work-zone warning family in Montana's manual. Construction and maintenance devices guide drivers and pedestrians around unusual or potentially dangerous conditions, and signs may announce that workers or repairs are ahead. Blue is not the listed basic work-zone color, while purple and brown do not serve as the manual's answer. Seeing orange should prompt caution, attention to flaggers or panels, and compliance with the posted work-zone speed.
The classification tells you what a sign is trying to do. Regulatory signs command or prohibit an action, warning signs call attention to danger, and information guide signs help with travel information. The other groupings describe locations, services, or duration rather than the manual's functional system. Identifying the category helps you choose the right response: obey a rule, prepare for a hazard, or use the information to navigate.
The red circle and slash is a prohibition device. Montana explains that the driver must not perform whatever action the black arrow or symbol depicts. It is not a command to do that action, a route marker, or a weather recommendation. Read the underlying symbol carefully because the slash applies to its pictured movement. A turn, entry, or other maneuver shown beneath the mark is therefore forbidden wherever the sign governs.

Laws and paperwork

A basic Class D license can remain valid from four through eight years, depending on the holder and the expiration rules. Two years is too short for the ordinary license period, while ten years is longer than the manual allows. The practical cue is to check the expiration date printed on the credential rather than assume every license lasts the same number of years.
Without an approved traffic education course, the applicant must be at least 16 for a learner license. The 15 year option applies only when the applicant has successfully completed approved driver education, and 14 is associated with a different traffic education pathway. Remember the age distinction before choosing an answer: education can lower the minimum from 16 to 15, but it does not make every age eligible.
A driver younger than 18 must hold the learner license for at least six consecutive months before applying for the first-year restricted license. Three months does not satisfy the minimum, and twelve months confuses the holding period with the learner license validity period, which can be up to one year. The useful memory cue is six months held continuously before moving to the next graduated step.
The supervised practice requirement is at least 50 total hours, including 10 hours at night, during a minimum six month period. The ten hour figure is a portion of the total, not an optional suggestion, and five hours is insufficient. A helpful study cue is to pair the numbers: 50 total hours, 10 nighttime hours, and six months of practice.
Montana requires every person in the vehicle to wear a seatbelt during this permit stage. That includes the teen driver and each passenger, so fastening only the driver’s belt leaves the rule unmet. A helmet is not the restraint requirement for occupants of a car, and highway travel does not create the duty. Make belt use part of the start-up routine by checking every seat before moving.
The first-year restricted license bars teenage driving between 11:00 p.m. and 5:00 a.m., subject to limited exceptions such as emergencies, school, church, work, and certain parent-authorized purposes. The other time ranges change one or both endpoints and therefore do not state the restriction. When studying the rule, remember the overnight window as eleven at night through five in the morning.
For the first six months, the teen may carry only one unrelated passenger younger than 18 unless a licensed adult driver supervises. The three passenger limit belongs to the second six months, so it is not the rule for the opening period. The word unrelated also matters: do not turn the limit into a blanket ban on every passenger. Check the supervision condition before counting seats.
High beam headlights must illuminate persons or vehicles for 350 feet, while low beam headlights must reach 100 feet. The 350 foot figure therefore belongs to high beam. The longer reach does not mean high beams are always appropriate because they must be dimmed when meeting or following other vehicles at the distances stated in the manual. Remember the pairing: brights reach 350 feet and dim lights reach 100 feet. Use the lower beam whenever another road user could be dazzled.
Montana requires at least $25,000 for bodily injury or death of one person in any one accident. The $50,000 amount covers bodily injury or death of two people, while $20,000 applies to property damage. Match the dollar figure to the type and number of losses, because the three minimum coverage amounts describe different parts of the required liability policy. Keep those categories separate when reviewing insurance documents.
Starting January 1, 2018, a 3 percent administrative fee is added to all Montana MVD products and services, on top of the listed license, permit and endorsement fees, which are subject to change. Over 80 forms and manuals are available free on the MVD forms website, and the fee section of the manual lists the exact charges for each transaction.
Montana requires at least $20,000 for injury to or destruction of another person’s property in one accident. Bodily-injury limits are separate: $25,000 for one person and $50,000 for two or more people. Match the coverage amount to the type of loss asked about. Keep the per-person, per-accident, and property-damage categories separate when checking the policy, because the limits apply to different kinds of loss.
The instruction-permit requirement combines a total and a nighttime minimum: at least 50 supervised hours, with 10 of those hours at night. The nighttime portion is included within the total, not added on top of it. Forty, 60 without a night component, and 25 hours each change a specific part of the requirement. Remember the pair as 50 total and 10 night during the supervised practice period.
A Class D basic driver license allows you to drive any non commercial vehicle under 26,000 pounds gross vehicle weight. Tractor trailers and other commercial vehicles fall outside that description, and a motorcycle of any size is not what the Class D description covers. Limiting the license to passenger cars is too narrow, because the rule is written by vehicle weight and commercial status rather than body style. Fees are listed in the fee section of the manual.
Before advancing to the first-year restricted license step, the teen must have no traffic violations or alcohol or drug offenses during the preceding six months. The rule is a recent record requirement, not a 30-day window or a lifetime statement about alcohol. It also applies before the step change, so an offense during that period prevents advancement. Track the six-month period from the intended transition date.
Those who have the military exemption may drive on that license for up to 90 days after honorable separation from the military. A driver also has a grace period of 3 months after the expiration date, or 90 days after honorable discharge, to renew and avoid the penalty of retesting. Renewal after that window means taking the tests again, so renew before the 90 days run out.
A driver has a grace period of 3 months after the expiration date, or 90 days after honorable discharge from the military, to renew and avoid the penalty of testing. After the grace period the applicant must pass the tests again. Renewals can be done online or by mail with an eye evaluation and medical evaluation form for eligible drivers.
The passenger restriction expands during the second six-month period to three unrelated passengers under 18, unless a licensed adult driver is supervising. One is the first-period number, not the later one. Two and four do not match the stated limit. Think of the progression as one passenger first, then three during the second half of the restricted year, while keeping the adult-supervision exception in view.
Montana lists travel to and from school, church, or work among the limited exceptions to the 11:00 p.m. to 5:00 a.m. restriction. The other choices describe personal convenience or entertainment, which the manual does not identify as exceptions. This is a condition question: the destination and purpose matter, not simply whether the driver feels capable or has a passenger along.
The restrictions end automatically at the date printed on the back of the license or when the individual turns 18, whichever occurs first. That means the earlier event controls; the driver does not wait for both events. Extra practice hours and court action are not listed as termination requirements. Read the phrase whichever occurs first literally, because it resolves the timing question.
Vehicles manufactured after January 1, 1956 must emit white or amber light to the front and red or amber light to the rear, visible for 500 feet, and must have two tail lamps except motorcycles, motor driven cycles, quadricycles and truck tractors. The license plate lamp must light the plate for 50 feet, and mirrors must give 200 feet of visibility to the rear.
High beams must be dimmed when meeting other vehicles at 1,000 feet and when overtaking or following other vehicles at 500 feet. Reflectors on the vehicle must be visible from 600 to 1,000 feet under high beams. The two distances differ because one applies to oncoming traffic and the other to a vehicle ahead in your direction, so 200 feet in both cases or a 300 and 100 foot pair do not match the manual. Dimming is required by distance, not by a flash from the other driver.
Montana requires high beams to be dimmed when meeting an oncoming vehicle at 1,000 feet. That distance protects the other driver from glare while both vehicles approach. The 500 foot figure applies when overtaking another vehicle, which is a different relationship and direction of travel. Do not wait until the approaching headlights are close; recognize the meeting situation early, switch to low beam, and restore high beam only after the vehicles have safely passed and conditions allow it.
Vehicles manufactured after January 1, 1956 must provide 200 foot visibility to the rear through their mirrors. The same equipment section requires front seat belts on vehicles built between January 1, 1965 and January 1, 1968, and belts for every designated seat on vehicles built after that. Fifty and 1,000 feet do not match the mirror rule, and there is a mirror requirement. For full equipment details the manual refers drivers to Montana Code Annotated Title 61, chapter 9, with copies generally available in county courthouses and most libraries.
Every trailer, semi trailer, or pole trailer of 3,000 pounds gross vehicle weight or less must have on the front a steel chain or cable fastened securely to the towing unit, and that chain or cable must be no less than a quarter inch in diameter. A rope of any size does not meet the rule, and a hitch rating does not replace the chain. The rule applies to these lighter trailers, so limiting chains to trailers over 10,000 pounds reverses it. Trailers with a gross weight over 3,000 pounds must instead have break away brakes.
Montana requires headlamps whenever weather or blowing dust reduces visibility to less than 500 feet. The purpose is both to illuminate the road and to help other road users see the vehicle. Parking lights alone do not satisfy that requirement, and hazard flashers do not replace headlamps. The cue is a major loss of sight distance, not merely darkness. Turn on the headlamps early, reduce speed to match what you can see, and leave enough room to stop safely.
No person may drive a motor vehicle in Montana unless each occupant is wearing a properly adjusted and fastened safety belt, and a driver who violates the law will be fined $20. Montana law places responsibility on the driver to ensure each occupant is properly buckled or in a child safety seat. The manual adds that whenever possible, children under age 13 should be secured in the backseat. Buckle up on every trip, even short trips at low speeds.
Montana updated its child restraint law in 2021 and 2025, replacing the older rule based on age 6 and 60 pounds. Children under 2 must ride rear-facing, children from 2 up to 4 must use a rear-facing or forward-facing seat with an internal harness, and children from 4 up to 8 use a harness seat or a booster with a lap and shoulder belt. An adult's arms are never a substitute: in a 30 mph crash a 100 pound adult becomes a 3,000 pound force against a child held in the lap.
Studded tires are not allowed in Montana from June 1 through September 30. The manual explains that special studded tires are allowed in some areas with a lot of icy weather, but because these tires can cause road damage they are not allowed in many areas or on certain roads. The rule is seasonal rather than year round, and it does not match a November through March window or an interstate only limit. On ice, slow to a crawl.
Young men who are at least 15 years old and not older than 26 are required to register with the Selective Service in compliance with the federal Military Selective Service Act. The manual says an individual must be able to meet those registration requirements when applying for an instruction permit, basic driver license, CDL, or Montana ID card, and a 15 to 17 year old must be able to be registered upon turning 18. The opportunity to register is offered on the application at a Montana driver licensing exam station.
In 1913 the Legislature recognized motor vehicles as property, put taxation on motor vehicles into effect to fund highway construction and maintenance, and began registration recording each vehicle's identifying features and the owner's name and address. The 1915 plates displayed MON, the year and the number, and the first prison made plates appeared in 1928, with county prefix numbers added in 1933.
Montana lets a teen get a learner license as early as 14 and a half, but only while participating in or after completing a state-approved traffic education program. Parent consent is required for anyone under 18, yet it does not lower the age to 14 by itself. The 15 year route also depends on an approved course, and online courses are not approved, so an online class does not qualify. Sixteen is the age for a learner license without traffic education, not the earliest possible age.
A learner license is valid for a Class D vehicle only when the teen is accompanied by a licensed driver education instructor, a parent or legal guardian, or another adult who has the parent's or guardian's permission, and that person must occupy the seat beside the driver. The GDL section adds that the supervising parent, guardian, or authorized adult must be licensed, so an unlicensed adult does not qualify. A 16 year old friend is not an adult supervisor, and the back seat is the wrong place. Instructors are one option, not the only one.
A teen under 18 needs a consent form signed by a parent or guardian before testing can begin. Signing is not a formality about the birth date or a statement about driver education. It obligates the parent or guardian to accept financial responsibility for any damage that results from the minor operating a motor vehicle. The form does not require the parent to supervise every trip; supervision rules come from the learner license and GDL steps instead. Parents should understand that the signature carries real financial risk.
Montana penalizes violations of the first-year restricted license, such as the 11:00 p.m. to 5:00 a.m. night limit or the passenger limit. A first offense brings between 20 and 60 hours of community service. The six month suspension is the penalty for a second offense, so it is too severe for a first. A warning with no consequence understates the rule, and the manual lists no $500 fine or license loss for a first violation. Repeat violations escalate quickly, so the restrictions deserve respect from the first day.
The second offense is where Montana moves from community service to losing the license: the teen's driver license is suspended for six months. Community service of 20 to 60 hours is the first offense penalty, so repeating it misstates the escalation. The manual does not revoke the license until age 21 for a restriction violation, and it does not make the teen restart the supervised practice hours. Remember the two steps: service hours the first time, a six month suspension the second time.
Montana ties the expiration of a license issued to anyone under 21 to the 21st birthday, not to a fixed number of years. The eight year term applies to drivers between 21 and 75, and the four year term applies to drivers 75 and older, so neither fits a 17 year old. The 18th birthday can end the first-year restrictions, but the license itself stays valid until age 21, when the driver renews into an adult term.
A Montana driver license receipt is valid for one year, and for applicants who are testing it covers three attempts within that year to pass every required exam. Unlimited tries overstates it, while one attempt or two attempts in six months understate it. Receipts are not renewable. If the applicant does not finish the licensing process within the year, the applicant must reapply and start over, so plan study time before booking tests.
Montana allows renewal up to six months before the expiration date. Three months is the grace period after expiration, during which a driver can still renew without retesting, so it describes the other side of the window. Nine or twelve months early is outside the allowed period. An expired license is not valid for driving, even during the grace period, and a license more than three months expired means reapplying as a new driver and passing all applicable tests.
Montana requires drivers to notify the Driver Services Bureau of the Department of Justice within 10 days of any change of address. Fifteen or thirty days is too late, and waiting for renewal could leave the state unable to reach you for years. The deadline matters because the licensing authority may need to send orders or requirements about your driving privilege, and a driver who never receives them can lose the privilege without knowing why.
A new Montana resident may drive on a valid license from the previous jurisdiction for up to 60 consecutive days, then must surrender it and qualify for a Montana license. The 30 day figure applies to commercial license holders, not a basic Class D driver. Ninety days is the military separation window, and the old license does not stay good until its own expiration date. A valid out of state license in the driver's possession can usually be exchanged without a written or road test.
Montana will not let a driver escape a suspension by changing states. A person cannot apply for, be issued, or retain a Montana driver license while suspended or revoked in any other state or jurisdiction. Passing the vision, written, and road tests does not override that bar, and the manual describes no work travel license for this situation. The same rule appears in the GDL section and the renewal section, which shows how central it is. Resolve the other state's suspension first.
Driving on Montana roads without a valid liability policy is a misdemeanor, and a first offense is punishable by a fine of at least $250 and no more than $500, or up to 10 days in the county jail, or both. It also puts 5 points on the driving record. A $50 fine understates the offense, and the manual lists no automatic one year revocation for a first offense. A fine of $1,000 or more is well above the stated maximum, and repeat offenses carry heavier penalties.
Along with a fine of $250 to $500, a first conviction for driving without valid liability insurance adds 5 points to the Montana driving record. Two or three points understates the record damage, and 10 points is double the stated figure. Insurance must be in effect for the vehicle being driven, and drivers must show evidence of it when stopped by law enforcement or involved in a collision. Points add up over time, and enough of them can lead to losing the license.
When a court finds a driver responsible for crash damages and the driver fails to pay within 60 days, the license and registration suspension is automatic. It remains in effect until the amount has been paid or 6 years have elapsed. A 30 day or one year suspension understates how long an unpaid judgment can follow a driver. Buying insurance does not end it either, although the driver will also have to submit evidence of motor vehicle insurance.
The manual recommends booster seats for older children until the vehicle's lap and shoulder belt fits properly, which usually happens when a child is about 4 feet 9 inches tall. Four feet and three and a half feet are too short for an adult belt to fit well, and waiting until 5 feet 6 inches goes beyond the manual's guidance. Current Montana law requires a harnessed seat or a booster with a lap and shoulder belt from age 4 up to 8, and an adult belt once a child is 9 or has outgrown the booster's limits.
Montana requires every occupant to wear a properly adjusted and fastened safety belt, and the driver is responsible for making sure everyone is buckled. Exceptions are narrow: vehicles made before January 1, 1968, operators of special mobile equipment, and occupants who carry a written statement from a physician saying they cannot wear a belt for medical reasons. Short trips are not exempt, a modern vehicle's back seat is covered, and no private waiver exists. The driver's fine is $20.
Headlamps are required at all times from a half hour after sunset to a half hour before sunrise, and at any other time when weather or blowing dust cuts visibility below 500 feet. Reversing the half hours, so the period starts before sunset and ends after sunrise, gets the rule backward. Sunset to sunrise leaves out the half hour margins, and streetlights do not replace the rule. At dusk or on overcast days, turning headlights on earlier is still wise.
The manual notes that most Montana cities have passed laws against texting and talking on cell phones while driving, so a driver can be cited under a local ordinance. Saying no city regulates phone use contradicts that statement, and the local laws cover texting as well as talking rather than allowing texts. Nothing limits these laws to school zones. The manual's advice is simpler than any ordinance: never text or talk on the phone while driving, and pull over and stop first.

Emergencies

After clearing an intersection, the driver should pull to the right and remain stopped until the emergency vehicle has passed. Continuing through several intersections delays the emergency response, and stopping where traffic is blocked creates another hazard. Following the emergency vehicle is not required and can interfere with its path. The sequence is simple: clear the intersection if necessary, move right, then stay stopped.
When possible, Montana advises moving into a lane farther away from a stationary emergency or police vehicle displaying emergency signals. That extra lateral distance gives responders more working room. Moving closer reduces the buffer, stopping beside the vehicle can obstruct traffic, and staying in the adjacent lane ignores the safer option when another lane is open. The manual also requires a speed reduction on highways posted at 50 mph or more, so drivers should combine both protections when the situation allows.
When a train warning requires a stop, the vehicle must be positioned as close as practicable to the crossing but at least 15 feet from the nearest rail. Five feet is too close, and the 50-foot choice confuses a parking restriction with the stopping rule. Reaching the rail before stopping defeats the safety purpose. Leave room for the train, watch every track, and cross only when the route beyond is clear.
On a highway posted at 50 MPH or more, traffic in the lane directly beside a stationary emergency or police vehicle displaying emergency signals must slow to at least 20 miles below the posted limit. If possible, change to a farther lane as well. Keeping full speed exposes responders to passing traffic, while stopping beside them or accelerating creates another hazard. Scan ahead for emergency lights and plan the lane change early.
Drivers must yield to an approaching emergency vehicle and, when possible and safe, pull to the right edge and stop. Stopping in the center blocks the responder, while acceleration and ordinary continuation disregard the emergency vehicle's priority. Check mirrors, signal your movement, and create a clear path without making a sudden maneuver. Reenter traffic only after the emergency vehicle has passed and the roadway is safe.
A driver already in a roundabout should not pull over or stop inside the circle for an emergency vehicle. Continue around, exit normally, and pull right where there is room for the responder to pass. Stopping, reversing, or entering the center island creates an unpredictable obstruction. If you are approaching the roundabout, pull over only when there is room; otherwise proceed through and stop after exiting.
An emergency vehicle needs a predictable path, and stopping inside the intersection can block that path. Montana directs a driver already in the intersection to clear it before pulling to the right edge or as near right as possible. Then remain stopped until the vehicle passes. The immediate stop sounds cautious, but its location creates an obstruction and may leave the emergency driver unable to maneuver. Watch the mirrors, finish crossing safely, signal if needed, and stop where the response vehicle has room.
When a vehicle becomes disabled, the safest first move is to get it off the roadway and away from traffic if that can be done. Once stopped safely, emergency flashers can make the problem visible and a warning device can alert approaching drivers. Standing in a lane exposes the driver to a secondary collision, while a hilltop or curve hides the disabled vehicle from others. Think in this order: escape moving traffic, make the vehicle visible, and seek help from a safe position.
As an alternative to the flares or lanterns otherwise required, three emergency reflective triangles conforming to USDOT Motor Vehicle Safety Standard 125 may be carried. All warning devices must be visible from at least 600 feet under normal atmospheric conditions at night. For a disabled vehicle, the manual advises placing warning devices such as flares behind the vehicle so other drivers can change lanes if necessary. A single flashlight or a white flag is not the listed alternative, and flares are not the only permitted option.
A siren or air horn paired with a flashing red or blue light signals that the emergency vehicle has priority. Montana requires other drivers to yield, move to the right edge or as near right as possible, and remain stopped until the vehicle has passed. Keeping speed or stopping in an intersection can obstruct the response route. Check mirrors promptly, signal the move when useful, clear an intersection first if you are already in it, and stay stopped until the emergency vehicle is safely beyond you.
If a disabled vehicle cannot be moved from the roadway, Montana advises stopping where other drivers have a clear view and warning road users that the vehicle is present. Emergency flashers, flares, or another warning device can help drivers change lanes. Stopping just over a hill or around a curve hides the hazard until it is too late. The driver should never stand in the travel lane. Choose visibility and personal safety together, using a safe roadside position while help is arranged.
Montana requires drivers to yield to an emergency vehicle using a siren or air horn with a flashing red or blue light. Pull as near to the right edge as possible, stop, and remain stopped until the vehicle passes. If you are already in an intersection, clear it first, then pull over safely. Stopping in the intersection can obstruct the responder, and moving left may place your vehicle in its path. The cue is the combination of audible and visual emergency signals, followed by a deliberate right-side stop.
For a slide, Montana emphasizes control through smooth correction. Stay off the brake while the vehicle slows, remove your foot from the accelerator, look where you want to go, and steer in that direction. Hard braking can worsen the skid before the tires regain grip, while acceleration adds force without solving the traction problem. Turning opposite the desired path can send the vehicle into a new skid. Keep your eyes on the intended route and make quick, measured steering changes as the vehicle begins to straighten.
The accident procedure requires police notification when any person is injured or killed. Whether the vehicles remain driveable does not erase that duty, and exchanging insurance information is an additional step rather than a replacement for contacting authorities. The owner-only option is too narrow because the obligation applies to the involved driver. Leaving after a private exchange can abandon people who need help and fails the stated reporting rule. A practical cue is injury or death changes a routine information exchange into an immediate law-enforcement report.
A loss of normal braking calls for a controlled sequence. Montana advises pumping the pedal several times because that may build enough pressure to stop. Snatching the parking brake can lock the rear wheels, and switching off the ignition at speed is not the first step listed for brake failure. Reverse gear is not an emergency stopping method. If pumping fails, use the parking brake gradually, then lower gears and a safe place off the road.
A stuck accelerator requires the driver to separate engine power from the wheels while keeping control. The manual directs the driver to keep watching the road and quickly shift to neutral, then apply steady brake pressure, pull off safely, and turn off the engine. Repeatedly pumping the accelerator can preserve the problem. Steering away before slowing increases risk, and opening the hood is impossible to do safely while moving.
The manual sets a 10 day deadline to file the accident report after a reportable crash, such as one where someone is injured or killed. Twenty four hours and five days are shorter than the stated deadline, and thirty days is too late. Report forms are available at law enforcement agencies and from most insurance agents. If the driver is injured and cannot complete the report, someone else can file it for the driver, so an injury does not cancel the duty to report.

Signs

Sign shape and color carry meaning before you even read the words. A red octagon always means stop, a red-bordered triangle pointing down means yield, and yellow diamonds warn of a hazard ahead.
