Most-missed Nevada DMV rules
These are the numbers and rules that trip up new drivers most often on the real Nevada knowledge test. Every fact below comes from our free Nevada DMV practice test question bank, which has 180 questions across 9 topics.
Speed limits
- Nevada's Basic Speed Rule requires drivers to reduce speed below the posted limit when conditions like fog, rain, or poor visibility make the posted limit unsafe.
- The handbook notes that driving unreasonably slowly for the conditions and road type is also unsafe and citable, not just speeding.
- Nevada's speed guidance states slower traffic should move right on multi-lane roads to let faster vehicles overtake safely.
- The Nevada handbook's speed limit examples list 25 mph for business and residential districts as well as school zones.
- School zone limits of 15 or 25 mph apply from a half hour before school starts until a half hour after it ends on school days.
- Nevada posts 65 mph as a common speed limit on urban freeways and rural highways, with 70+ mph on rural interstates.
- Nevada law doubles speeding fines within work zones.
Right of way
- When there are no signs or signals, Nevada rules state the vehicle arriving from the right generally has the right to go first.
- Nevada rules give right of way to a vehicle already established in the intersection over one that is just entering.
- Nevada rules state a vehicle going straight through an intersection has the right of way over one turning left across its path.
- Vehicles entering a road from a driveway, private road, or minor road must yield to all traffic and pedestrians already on the main roadway.
- Drivers entering a freeway are expected to yield to the traffic already moving on the freeway before merging.
- Nevada law requires drivers to yield to emergency vehicles by pulling to the right, avoiding intersections, and stopping until the emergency vehicle passes.
- Pedestrians in or entering crosswalks have the right of way under Nevada rules, and drivers must yield accordingly.
- Nevada law specifically grants right of way to a blind or visually impaired pedestrian using a guide dog, service animal, or white cane on any highway, street, or road in the state.
- Nevada rules call for yielding to funeral processions and letting the group of vehicles with headlights on pass through together, even at signals.
- Nevada expressly prohibits motor vehicles from traveling in a marked bicycle lane.
- Nevada's handbook explicitly states that right-of-way rules only determine who must yield; drivers must still act to avoid a crash rather than assuming they are protected.
- A stop sign requires a full, complete stop every time, followed by yielding the right-of-way to cross traffic and pedestrians before moving forward.
- When vehicles reach a four-way stop at the same time, the standard rule is that the vehicle to the right goes first, since each driver yields to the car on their right.
- Do not cut through or break up a funeral procession. Slow down, be patient, and let it pass. Cutting between the vehicles is unsafe and often illegal.
- At an uncontrolled intersection, slow down and yield to any car already in the intersection or approaching from your right.
- A left-turning vehicle must yield to oncoming through traffic and to pedestrians. Only turn when the gap is safe.
- When entering a roundabout, yield to traffic already circulating and travel counterclockwise. Exit at your street; do not stop in the middle of the circle.
- At a T-intersection, traffic on the road that ends must yield to traffic on the through road that continues.
- A round green light allows a left turn but does not give you the right of way. Pull into the intersection, yield to oncoming through traffic and pedestrians, then turn when there is a safe gap.
Alcohol and DUI
- For adult drivers, a BAC of .08% or more triggers Nevada's Illegal Per Se administrative revocation along with possible SR-22 filing and criminal DUI penalties.
- Commercial driver's license holders in Nevada face DUI-related consequences at a lower BAC range, from about .04% up to .08%, stricter than the standard threshold.
- Nevada requires DUI school or an educational program as part of penalties following a DUI conviction, in addition to potential jail time, fines, or community service.
- Drivers under 21 involved in DUI incidents in Nevada may be required to undergo an alcohol or drug abuse evaluation and possible court-ordered treatment.
- While the standard limit is 0.08% (0.04% for CDL holders), drivers under 21 face a 0.02% limit.
- A first DUI offense carries a minimum license revocation of 185 days, along with jail time or community service and mandatory DUI school.
- A second DUI within 7 years results in a one year license revocation, jail/confinement of 10 days to 6 months, and fines of $750 to $1,000.
- A third or subsequent DUI within 7 years is a felony with 3 year license revocation and 1 to 6 years in prison.
- DUI causing death or substantial bodily harm carries a 3 year license revocation plus 2 to 20 years in prison and a $2,000-$5,000 fine.
- A first refusal under Nevada's Implied Consent Law results in a one year revocation of driving privileges.
- This is an administrative revocation of 185 days, separate from any criminal DUI penalties.
Signals and markings
- Nevada roundabouts operate with counterclockwise traffic flow, as described in the handbook's roundabout section.
- Nevada's handbook instructs that entering traffic must always yield to vehicles already circulating in the roundabout.
- Nevada law requires dimming high beams at least 500 feet before an oncoming vehicle, and 300 feet before a vehicle being followed.
- Nevada law requires signaling at least 300 feet ahead on open highways, compared to 100 feet on city streets.
- Double solid yellow lines indicate that passing is not permitted from either direction on that stretch of road.
- A steady yellow signal warns that the light is about to turn red, so drivers should stop if they can do so safely.
- A green arrow gives the protected right-of-way to proceed in that direction, though the driver must still yield to anyone already in the intersection.
- A flashing yellow signal warns drivers to slow down and proceed carefully through the intersection, unlike a dark signal which is treated as a stop.
- A green arrow grants a protected right of way to complete that turn without yielding to opposing traffic.
- A law enforcement officer's directions override traffic signals, so drivers must obey the officer even if it means stopping on a green light.
- A flashing red signal functions like a stop sign, requiring drivers to come to a complete stop before proceeding when safe.
- The truck apron is a raised, paved area only meant for large truck wheels; ordinary vehicles should never drive on it.
- A solid yellow line on a driver's side of the centerline indicates that passing is prohibited from that side of the road.
- A steady red light always requires a complete stop before the intersection unless a sign specifically permits turning after stopping.
- A solid yellow line on your side of the centerline indicates no passing is permitted from your side of the road.
- A flashing yellow signal warns drivers to proceed through the intersection with caution rather than requiring a full stop.
- The manual instructs drivers not to change lanes once inside a roundabout.
- A flashing yellow light warns drivers to slow down and proceed carefully, unlike a flashing red which requires a full stop.
- A red flashing light is treated like a stop sign: stop, then yield to vehicles already in or entering the intersection.
- A flashing red signal functions like a stop sign, requiring drivers to come to a complete stop before proceeding when it is safe.
- Even on a green arrow, a driver must yield to other vehicles already lawfully in the intersection.
- A flashing yellow light means slow down, look, and proceed carefully. It does NOT require a full stop the way a red light or STOP sign does.
- A flashing hand or countdown means do NOT start crossing. If you are already in the crosswalk, keep going and finish crossing safely.
- A steady DON'T WALK hand prohibits starting to cross. Only a WALK signal or walking-person symbol allows you to begin crossing.
- Always signal continuously through a turn or lane change even when you see no other cars, because pedestrians or cyclists may be near. Cancel the signal after you finish.
- A green downward arrow means the lane is open for you to use. A red X above the lane means it is closed and you may not drive in it.
- Double solid yellow lines separate opposing directions and prohibit passing. You may only cross them for a permitted left turn or a legal U-turn into an intersection or driveway.
- A broken yellow line on your side of the lane allows passing when it is safe. The solid line on the opposite side means that direction may not pass.
- White lines separate lanes going the same direction. A solid white line means stay in your lane and avoid changing lanes, while a broken white line lets you change lanes when safe.
- A two-way center left-turn lane is only for preparing to turn left or merging into traffic. You may not use it to drive straight through or to pass.
Parking
- Nevada's U-turn restriction in school zones includes an exception for days when school is not in session, making the U-turn permissible in that circumstance.
- Nevada prohibits parking within 15 feet of a fire hydrant where parallel parking is allowed (20 feet if angle parking is permitted).
Safe driving
- Nevada requires a minimum of 3 feet of clearance when passing a bicyclist without a second lane, and prohibits moving back right until safely clear.
- The safe response to a skid is to ease off the gas and steer smoothly in the direction you want to travel, rather than braking hard or overcorrecting.
- General safe-driving principles hold that adverse weather reduces traction and visibility, requiring lower speeds than posted limits allow in good conditions.
- A minimum three-second following gap gives most drivers enough time to react and stop safely under normal conditions.
- Endangering a highway worker with no injury results in a fine of $500 to $1,000, rising to as much as $5,000 if great bodily injury results.
- A safe following distance gives a driver time to react and stop without a collision if traffic ahead slows or stops.
- The manual sets a specific cutoff allowing mopeds/scooters only on roads posted at 50 mph or lower.
- General right-of-way practice, reflected in the manual, is that the first vehicle to arrive and stop proceeds first; simultaneous arrivals yield to the right.
- Defensive driving calls for slowing down and preparing to stop when visibility of intersection controls is uncertain.
- A 3 to 4 second following distance gives drivers enough time to react and brake safely under normal conditions.
- Because safety corridors have higher serious-crash rates, drivers are encouraged to use headlights on to improve visibility and safety.
- Since farm tractors typically travel around 25 mph, the speed differential requires extra caution and clearance when passing.
- Wet roads increase stopping distance, so drivers should slow down and add extra space to compensate for reduced traction.
- Posted speed limits are for ideal conditions; drivers should reduce speed further and increase following distance in poor weather like heavy rain or fog.
- Work zones are posted at least 10 mph under the normal maximum speed specifically to protect workers and should always be observed.
- The manual requires dimming to low beams at least 300 feet before overtaking or following another vehicle.
- Passengers under 2 years old must specifically be secured in a rear-facing child restraint system.
- Because SMV-marked vehicles like tractors move slowly and may turn into fields or driveways, safe practice is to keep distance and watch for signals before passing.
- The manual requires headlights to be on whenever visibility is under 1,000 feet.
- With a tailgater, open up more space in front of you so you can brake gradually instead of suddenly. Do not brake to retaliate and do not race away.
- Strong crosswinds can push your car out of its lane. Hold the wheel firmly with both hands, slow down, and be ready for sudden gusts.
- Do not engage. Avoid eye contact, do not brake in retaliation, let them pass, and leave a safe distance between you and that car.
- Horses and livestock spook easily. Slow down, do not honk or rev your engine, and pass very slowly with plenty of room so you do not startle them.
- When you see a hazard developing ahead, cover the brake and plan an escape route so you can react faster if you have to stop.
- In a skid, ease off the gas or brake and steer gently in the direction you want the front of the car to go. Slamming the brakes makes the skid worse.
Road signs
- STOP (R1-1): full stop at the line or crosswalk even when empty; yield, then proceed.
- YIELD (R1-2): give up the right-of-way; slow and be ready to stop.
- DO NOT ENTER (R5-1): entry prohibited; common at freeway off-ramps and one-way streets.
- WRONG WAY (R5-1a): you have entered opposing traffic. Pull over safely and turn around when possible.
- ONE WAY (R6-1): all traffic flows in the arrow's direction.
- NO U-TURN (R3-4): no U-turns at this location. This is not a no-left-turn sign (a different arrow shape) or a no-passing sign (a different shape and color entirely).
- NO LEFT TURN (R3-2). A red circle-and-slash always bans the pictured movement.
- NO RIGHT TURN (R3-1): no right turns, including on red. Going straight is still fine since the sign only bans the right-turn movement; parking is unrelated to this sign.
- White/black = regulatory. Speed Limit is the legal max in ideal conditions; drive slower when conditions are bad (Basic Speed Law).
- KEEP RIGHT (R4-7): a median or obstruction is ahead; keep to its right.
- The crossbuck (R15-1) stands at the tracks and legally works like a YIELD sign: slow, look both ways, be ready to stop.
- Advance warning (W10-1): tracks ahead. Slow down, look, and listen.
- School (S1-1): school zone or crossing. Slow down and watch for children; obey the posted reduced school-zone speed limit, which varies by state.
- Pedestrian crossing (W11-2): crossing ahead; slow and be ready to stop.
- Signal ahead (W3-3): an intersection signal is coming, useful when it hides behind a curve.
- Stop ahead (W3-1): a stop sign is coming (often obscured); start slowing now.
- Merge (W4-1): traffic joins ahead. Adjust speed and position to let them in safely.
- Lane ends (W4-2): merge early; zipper-merge when traffic is heavy.
- Two-way traffic (W6-3): you are leaving a one-way road; keep right.
- Divided highway begins (W6-1): directions separate around a median; always keep right of it.
- Slippery when wet (W8-5): slickest in fresh rain. Slow down, keep distance, steer smoothly.
- Curve (W1-2): slow BEFORE the curve; do not brake in the middle of it.
- Turn (W1-1): sharper than a curve; slow down hard, follow the advisory plaque.
- Winding road (W1-5): consecutive curves; hold a steady lower speed throughout.
- Crossroad (W2-1): an intersection ahead with traffic entering from both sides. Hospital signs are blue with an H.
- NO PASSING ZONE (W14-3): unique pennant shape, posted on the LEFT side, marks where passing becomes illegal.
- The eight-sided octagon shape is reserved exclusively for Stop signs so it can be recognized even from behind or in poor visibility.
- Orange is the standard color used for temporary construction and work zone signs, regardless of the specific shape used.
- Diamond-shaped yellow signs are standard warning signs alerting drivers to hazards ahead, such as curves, merges, or intersections.
- A YIELD sign requires slowing down and stopping only if needed to give way to traffic or pedestrians on the intersecting road.
- Yellow diamond signs are standard warning signs alerting drivers to hazards or changing road conditions ahead.
- Yellow warning signage in this context provides an advisory safe speed recommendation for hazards like curves, distinct from a legally binding limit.
- Diamond-shaped yellow signs are standard warning signs alerting drivers to hazards like curves, merges, or crossings ahead.
- School zone warning signs signal drivers to reduce speed and watch for children, consistent with the guide's emphasis on adjusting speed for conditions and hazards.
- An inverted triangle is the standard shape used for yield signs, instructing drivers to slow and give way to other traffic.
- The downward-pointing triangle is the standard yield sign shape, meaning drivers must slow and give the right of way if needed rather than always stopping.
- The downward-pointing red-and-white triangle is the standard YIELD sign, requiring drivers to slow and yield to conflicting traffic.
- At a yield sign, drivers must slow or stop as needed to let crossing or oncoming traffic clear before proceeding safely.
- The triangular yield sign shape signals drivers to give the right-of-way as needed to other traffic or pedestrians.
- The eight-sided shape is reserved exclusively for stop signs so drivers can recognize it even if the sign face is obscured.
- The yellow pennant-shaped sign marks the start of a no-passing zone. It usually appears along with a solid yellow line on the pavement.
- A yellow diamond-shaped sign is a WARNING sign, alerting you to a hazard or change ahead such as a curve, intersection, or school, so you slow down.
- A white rectangular sign with black lettering is a REGULATORY sign stating a law you must obey, such as speed or direction of travel.
- An orange sign marks a construction or roadwork zone. Slow down and watch for workers and shifting lanes.
- A blue sign points to driver services such as gas stations, food, lodging, or hospitals.
- A green sign is a GUIDE sign, showing directions, distances, and the names of exits or places.
- A red circle with a slash means the action shown is PROHIBITED, such as no turn or no U-turn at that spot.
Laws and paperwork
- Nevada's law is broader than a typical move-over law, extending to stopped law enforcement, tow trucks, NDOT vehicles, garbage trucks, and utility vehicles displaying certain lights.
- Nevada specifically bans U-turns in school zones except when no children are present, school isn't in session that day, or it's outside the enforced time window.
- Nevada's open-container law prohibits opened alcoholic beverages in the driver and passenger compartments, with exceptions such as motorhome or trailer living quarters and certain commercial passenger vehicles.
- Nevada's open-container law exempts passenger areas of commercial buses, limousines, and taxis, along with motorhome or trailer living quarters.
- An SR-22 is a financial responsibility filing that can be required after a DUI-related administrative license action, such as Nevada's Illegal Per Se revocation, to demonstrate insurance coverage.
- Nevada's written knowledge test uses roughly an 80% passing threshold for the standard non-commercial license test.
- Nevada's online knowledge test for teens has an allotted time limit, while testing in person at a DMV office is not described as having a stated time limit.
- Nevada requires instruction permit holders under 18 to hold the permit for at least 6 months before getting a full license.
- NRS 483.2523 bars new teen drivers from carrying passengers under 18, other than immediate family, for their first 6 months of licensure.
- The curfew runs from 10 p.m. to 5 a.m. and remains in effect until the driver turns 18, regardless of when licensed.
- Permit holders are restricted to daylight riding, no passengers, no freeway riding, and must be supervised by an experienced licensed motorcyclist.
- Per NRS 483.280, failing the motorcycle skills test twice or more results in permanent denial of future motorcycle instruction permits.
- Nevada restricted licenses cover cases like age 14-15 hardship/school needs or drivers who served half their suspension/revocation.
- Nevada separately bans manual texting, reading, or other non-voice phone communications while driving.
Emergencies
- Nevada's law extends caution requirements to a vehicle being repaired on the roadside, not just emergency or law enforcement vehicles, requiring drivers to slow and move over when possible.
- NRS 484B.607 requires drivers to slow below the posted speed limit and move out of the lane next to the stopped vehicle when possible.
- Rapid brake lights or hazard signals ahead indicate a potential emergency or obstruction, so drivers should slow down and prepare to react safely.
- Drivers may not park their vehicle within the block where an emergency vehicle has stopped to respond to an incident.
- Drivers should move to the right and yield the roadway to approaching emergency vehicles with active lights and sirens, stopping if necessary to let them pass safely.
- The Move Over Law's amber-light tier covers highway maintenance vehicles, requiring drivers to move over or slow down similarly to emergency vehicles.
- Move Over laws require drivers to move over or slow down for any stopped vehicle with warning lights activated, to protect people near the roadway.
- On divided highways of 4+ lanes, drivers should move over a lane away from a stopped emergency vehicle when it can be done safely.
- The lane-change requirement applies on interstates and any multi-lane highway with four or more lanes that has at least two lanes traveling in the same direction.
- When changing lanes is not safe, the Move Over Law still expects drivers to reduce speed and use caution passing the stopped vehicle.
- Steering gently in the direction you want to go while easing off the accelerator helps regain control during a skid.
- Drivers must move over a lane or slow down when passing any stationary vehicle with flashing lights on the roadside, not just law enforcement vehicles.
- The manual notes you only have right of way if the other vehicle isn't already in the intersection, meaning a vehicle already there should be allowed to clear first.
- When a safe lane change isn't possible, drivers are generally expected to reduce speed and use caution passing the stopped vehicle.
- The manual notes that if you're already in an intersection when an emergency vehicle approaches, you should proceed through it first before pulling over to stop.
- Hazardous materials carriers must stop at every railroad crossing regardless of visible train activity, so drivers behind them should expect and safely wait through this stop.
- Drivers must yield to emergency vehicles by moving to the right shoulder; on a divided highway of 4+ lanes, they should move over a lane away if it is safe to do so.
- Drivers must yield right-of-way to emergency vehicles operating with active lights and siren.
- Drivers must yield to emergency vehicles by moving to the right edge of the roadway, staying clear of intersections, until it passes.
- Standard guidance for hydroplaning is to ease off the gas and avoid sudden braking or steering, letting the tires regain contact with the road.
- The manual instructs drivers to pull to the right edge and remain stopped until the emergency vehicle passes.
- Standard right-of-way and safe-driving practice requires yielding to emergency vehicles by pulling right and stopping until they pass.
- Drivers must yield right-of-way, pull as far right as possible, stop, and remain stopped until the emergency vehicle has passed.
- If your car catches fire or smells like burning, pull over, shut off the engine, and get everyone away. Do not open the hot hood, since the rush of air will make the fire flare up.
- If the gas pedal sticks, shift to Neutral to cut the power, then brake and steer to the shoulder. Only turn off the engine after you have fully stopped, so you do not lose power steering.
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.
