Most-missed Minnesota DMV rules

These are the numbers and rules that trip up new drivers most often on the real Minnesota knowledge test. Every fact below comes from our free Minnesota DMV practice test question bank, which has 180 questions across 8 topics.

Speed limits

The Basic Speed Law requires driving at a speed reasonable for existing conditions, so following the posted limit is not a defense if conditions call for slower driving.
The manual sets the default unposted alley speed limit at 10 mph.
The manual states the default unposted speed limit on urban/town roads is 30 mph.
The manual instructs drivers to slow down when children are present, even without a specific posted school-zone limit.
Minnesota adds an extra fine for speeding within a posted work/construction zone, on top of the standard speeding penalty.
This 10-mph passing allowance is limited specifically to lawfully passing on two-lane roads posted 55 mph or above.
Minnesota's default statutory speed limit for roads not otherwise specified is 55 mph.
A road authority may adopt a 25 mph limit for residential roadways (and 35 mph for rural residential districts), but these are optional, not default limits.
The commissioner may set minimum speed limits on trunk highways, and driving below the posted minimum is prima facie evidence of unlawful slow driving.

Right of way

At uncontrolled intersections or all-way stops, the driver on the left must yield to the driver arriving on the right at the same time.
Passing a vehicle that has stopped for a pedestrian is illegal in Minnesota, classified as a misdemeanor (and worse on repeat offenses).
Approaching an intersection at an unlawfully high speed causes a driver to lose whatever right-of-way privilege they would normally have had.
A flashing red signal functions like an all-way stop, requiring a full stop and the same right-of-way rules.
Left-turning drivers must yield the right-of-way to oncoming vehicles that are already in the intersection or close enough to present a danger.
Drivers must stop for pedestrians in crosswalks and may not proceed, or pass a vehicle stopped for a pedestrian, until the pedestrian has cleared the lane.
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

Minnesota's DWI threshold for regular drivers is a BAC of 0.08% or higher.
CDL holders face a lower DWI threshold of 0.04% while operating a commercial motor vehicle.
CDL drivers with any detectable alcohol below the 0.04% limit are taken out of service for 24 hours as a precaution.
Minnesota applies a strict no-tolerance rule for drivers under 21: any detectable alcohol is illegal, not just amounts above 0.02%.
A BAC of 0.16% or higher is treated as an aggravating factor, potentially leading to enhanced penalties like mandatory ignition interlock.
Minnesota measures BAC as of the time of driving or within two hours of driving or being in physical control of the vehicle.
First-degree DWI is triggered by aggravating factors such as a violation within 10 years of three or more prior qualified impaired driving incidents, a prior felony DWI conviction, or certain prior criminal vehicular operation convictions, carrying up to 7 years imprisonment and up to a $14,000 fine.
Minnesota's implied consent test-refusal license revocation is a minimum of 1 year for such drivers; repeat offenders face revocation tied to mandatory ignition interlock compliance.

Signals and markings

Blue warning lights are restricted by law to snowplows, road maintenance vehicles, and authorized emergency vehicles.
Strobe lamps are limited to school buses, snow removal equipment, and rural mail carrier vehicles in addition to emergency vehicles.
Headlights must be on from sunset to sunrise and any time visibility falls under the stated distance threshold in the manual.
Drivers must dim their headlights to low beam within the manual's specified distance of an oncoming or preceded vehicle.
When a signal is dark or malfunctioning, drivers must treat the intersection as a four-way stop, coming to a full stop and yielding to the vehicle on the right if both arrive at the same time.
A solid yellow line on a driver's side of the centerline indicates that passing is prohibited from that side of the road.
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 red signal functions like a stop sign, requiring drivers to come to a complete stop before proceeding when it is safe.
A bike box lets cyclists position ahead of traffic; drivers must stop behind the box rather than within it.
The manual requires dimming high beams for oncoming traffic to avoid blinding other drivers.
A yellow light signals that the light is about to change to red, and drivers should stop if they can do so safely rather than accelerate through it.
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 flashing yellow signal warns drivers to slow down and proceed carefully, unlike a solid red which requires a full stop.
A flashing red signal is legally equivalent to a stop sign: the driver must come to a full stop before proceeding when clear.
Broken white lines between same-direction lanes indicate that changing lanes is allowed when it can be done safely.
A steady yellow light warns that the signal is about to change to red, so drivers should slow and prepare to stop if it is safe to do so.
A steady yellow light warns that the right of way is ending and the signal is about to turn red.
A steady red signal requires a full stop; any right turn on red is only allowed after stopping and when safe and not prohibited by signage.
A solid yellow line on your side of the centerline means you may not cross it to pass; passing is prohibited from that side.
A flashing yellow signal warns drivers to slow down and proceed carefully, rather than requiring a full stop.
A steady yellow light warns the signal is about to turn red; drivers should stop safely if possible or proceed with caution if too close to stop.
A flashing yellow signal means drivers may proceed but should slow down and use extra caution.
A flashing red signal functions the same as a stop sign, requiring drivers to stop completely and then proceed only when it is safe.
The manual instructs drivers not to change lanes once inside a roundabout.
A flashing red signal is treated the same as a stop sign: come to a full stop, then proceed only when it is safe.
A flashing red signal functions like a stop sign, requiring drivers to come to a complete stop before proceeding when safe.
A solid red arrow requires a complete stop and prohibits the turn until the signal changes, unlike a flashing red or green arrow.
A solid yellow line on your side of the centerline means passing is not permitted there, usually due to reduced visibility or other roadway hazards.
Headlights are legally required not just at night but any time weather conditions significantly reduce visibility.
A flashing yellow signal is a caution indicator, telling drivers to slow down and proceed carefully rather than stop.
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.

Safe driving

Drivers must stop for a school bus with flashing red lights and remain stopped until the lights stop flashing, protecting children crossing.
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.
A time based following distance, counting seconds behind the vehicle ahead, adjusts naturally for speed and is the standard safe driving practice.
An owner cited by a stop-arm camera faces monetary penalties instead of points: $250 for a first violation, rising to $300 for a third within 18 months.
Children under 7 must use a child restraint system meeting 49 CFR 571.213 standards unless they are 57 inches or taller.
The manual requires dimming to low beams at least 300 feet before overtaking or following another vehicle.
On undivided roads, traffic in both directions must stop for a school bus with flashing red lights and an extended stop sign until it resumes moving.
The manual requires yielding to pedestrians, cyclists, and others still clearing the intersection even if you'd otherwise have priority.
A minimum 3-second following distance gives drivers enough time to react to sudden braking by the vehicle ahead.
Posted speed limits are for ideal conditions; drivers should reduce speed further and increase following distance in poor weather like heavy rain or fog.
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.
Hydroplaning occurs when water accumulates faster than tire treads can disperse it, causing loss of contact with the road.
The manual advises reducing speed for wet roads, reducing it further for packed snow, and slowing to a crawl on ice, since traction decreases as conditions worsen.
The manual teaches drivers not to swerve for animals, since swerving often causes worse crashes than a controlled collision or straight-line braking.
Passengers under 2 years old must specifically be secured in a rear-facing child restraint system.
Scanning further ahead gives drivers earlier warning of hazards, slowing traffic, or obstacles, allowing more time to react safely.
Wet roads increase stopping distance, so drivers should slow down and add extra space to compensate for reduced traction.
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 five-sided pentagon shape is reserved specifically for school-related warning signs, distinct from all other warning sign shapes.
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 circular yellow sign shape is specifically reserved in the national sign system for advance railroad crossing warnings.
The downward-pointing red-and-white triangle is the standard YIELD sign, requiring drivers to slow and yield to conflicting traffic.
A yield sign requires slowing and yielding to conflicting traffic, stopping only if needed to avoid a hazard.
Speed limit signs are standard rectangular white regulatory signs, distinct from the diamond-shaped yellow warning signs.
The triangular shape is uniquely reserved for Yield signs, telling drivers to slow and give way rather than come to a full stop.
Diamond-shaped yellow signs are warning signs, alerting drivers to hazards like curves, merges, or crossings ahead.
White rectangular signs with black lettering are the standard shape and color used for regulatory information like speed limits or turn rules.
The eight-sided red STOP sign requires a full stop before entering the intersection, regardless of visible cross traffic.
Diamond-shaped yellow signs are standard warning signs alerting drivers to hazards like curves, merges, or crossings ahead.
Yellow diamond signs are standard warning signs alerting drivers to hazards or changing road conditions ahead.
Warning signs (typically yellow, diamond shaped) inform drivers of hazards ahead like curves or crossings, distinct from regulatory signs that state legal requirements.
The eight-sided octagon shape is reserved exclusively for Stop signs so it can be recognized even from behind or in poor visibility.
A circular sign with a diagonal slash through it is used nationally to show that a prior restriction (like a speed limit) no longer applies.
The railroad advance warning sign is round with an X and R R symbol, one of the only circular warning signs used on US roads.
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.
The manual specifically calls out School Crossing signs with children present as requiring reduced speed.
Pentagon-shaped signs are used specifically to indicate school zones or school crossings, alerting drivers to reduce speed.
The downward-pointing red and white triangle is the standard yield sign, instructing drivers to slow and give way to traffic as needed, stopping only if required for safety.
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

Minnesota's school bus stop law requires stopping for flashing red lights even if the mechanical stop arm fails to extend.
The exception to Minnesota's school bus stop law applies to opposing traffic on a divided highway, which is not required to stop.
NEVs are restricted to streets posted 35 mph or lower and must be titled and registered, per the manual.
The manual states NEVs cannot be used to complete a driving road test.
The manual states a Class D applicant must score at least 80 percent to pass the written knowledge test.
The manual describes the Class D knowledge test as consisting of multiple choice and true/false questions.
The manual notes that after two consecutive failures, a fee applies to subsequent knowledge test attempts.
Under Minn. Stat. 171.055, Subd. 1(a)(1), a provisional license can be obtained at age 16.
During the first 6 months, only one passenger under age 20 who is not immediate family is allowed, unless a parent or guardian is present.
The passenger limit increases to three passengers under age 20 who are not immediate family during the second 6 months.
Provisional license holders face a midnight to 5:00 a.m. curfew during the first 6 months, with exceptions for employment, certain school events, or being accompanied by a licensed driver at least 25 years old.
Minnesota's hands-free law (169.475) bars holding a device to text, call, or view video/images/apps while driving, though voice-activated calling and GPS use without typing are allowed; a second or subsequent offense carries a $275 fine.

Emergencies

When changing lanes is not possible, the Move Over Law requires drivers to slow down instead.
Minnesota's Move Over Law extends to other authorized stopped vehicles, such as roadside workers, not solely police or emergency vehicles.
Minn. Stat. 169.18 requires drivers to move a full lane away from the stopped vehicle, or otherwise slow to a reasonable speed and pass with caution; violation is a petty misdemeanor with a fine up to $300 plus surcharges.
Sudden hard braking or sharp steering after a blowout can cause loss of control; easing off the gas while holding a straight line is safer.
Standard emergency procedure is to move fully onto the shoulder, activate hazard lights, and, if safe, move away from the travel lanes rather than stopping in traffic or continuing to drive on damaged equipment.
If pulling fully off the road isn't immediately possible, drivers should slow down and use extra caution, but the priority is always to get completely off the pavement as soon as safely possible per Pull Aside, Stay Alive guidance.
On typical two-lane roads, traffic in both directions must stop for a loading school bus; the opposite-direction exception applies only on wider divided highways.
When changing lanes is not safe, the Move Over Law still expects drivers to reduce speed and use caution passing the stopped vehicle.
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.
Pumping the brakes can build pressure in some systems, and downshifting uses engine braking to help slow the vehicle safely.
On divided highways of 4+ lanes, drivers should move over a lane away from a stopped emergency vehicle when it can be done safely.
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.
Authorized emergency vehicles may exceed posted limits during emergency duty with signals operating, as long as they do not endanger others.
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.
A move-over violation causing death carries a fine of up to $10,000 and a 1-year license suspension, compared to 90 days for bodily injury and 6 months for serious bodily injury.
Drivers must yield right-of-way to emergency vehicles operating with active lights and siren.
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.
Since moose eyes don't glow like deer eyes under headlights, drivers must scan for a large silhouette instead.
The Move Over Law has escalating consequences: a basic violation carries a modest fine and point penalty, a violation causing a crash carries a higher fine, and one causing death or serious injury carries the harshest penalty.
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. For every sign image used in our practice test, with the exact meaning and explanation, see the full road sign glossary.
