North Dakota Driving Laws 2026: Speed Limits, DUI BAC and NDDOT Road Rules for the Permit Test

What are the default speed limits in North Dakota when no sign is posted? North Dakota sets 25 mph in business and residential areas, 55 mph on paved two-lane county roads, 65 mph on rural paved roads, and 80 mph on rural interstates, one of the highest interstate limits in the US. DUI: 0.08% for adults, 0.02% for under-21. North Dakota headlights: required from sunset to sunrise and when weather or other conditions make a person or vehicle less than 1,000 feet ahead not clearly discernible. The point system: 12 points triggers a 7-day suspension.

1. ND Speed Limits: 80 MPH Rural Interstates, 70 Multi-Lane, 25 in Town, 20 Obstructed

What is the speed limit in a residential area in North Dakota, and what happens if no sign is posted? Speed limits are set by state law; when no sign is visible, these default limits apply:

Key test point: North Dakota's rural Interstate limit is 80 mph unless otherwise posted. The 20 mph rule applies when an obstructed railroad crossing or obstructed intersection is approached, and when passing a school during recess or while children are arriving or leaving during opening or closing hours, unless otherwise posted. Gravel, dirt, loose-surface roads and paved two-lane county or township roads with no posted limit are 55 mph. Rural paved two-lane highways may be posted at 65 mph. Never drive faster than conditions allow, even if under the posted limit.

2. North Dakota Right-of-Way: 4-Way Stops, T-Intersections & Freeway Merging

Who has the give, never something you take.right-of-way at a 4-way stop in North Dakota, and do pedestrians always go first? Right-of-way questions are among the most frequently tested; remember: right-of-way is something you

3. ND Turn Signal Law: Signal Continuously for the Last 100 Feet Before Every Turn

Can you turn right on red in North Dakota, and how far in advance must you signal a turn? Intersection and turn rules are heavily tested, including when left turns on red are legal and exactly how far in advance you must signal.

Right turn on red

Permitted after a full stop unless a sign prohibits it. Yield to pedestrians and cross traffic.

No right turn on red

When posted, you must wait for a green light before turning right.

Left turn on red

Left turn from two-way street

Start from the left lane; end in the left lane of the cross street.

Right turn

Stay as close to the right curb as possible; end in the right lane.

U-turns

Legal when it can be made safely without interfering with traffic. On a curve or near the crest of a grade, a U-turn is prohibited when the vehicle cannot be seen from 500 feet in either direction.

4. ND Lane Rules: Center Turn Lanes, Lane Changes & Multi-Lane Driving

When can you use the center turn lane in North Dakota, and what do solid versus broken yellow lines mean for passing? Lane rules determine where you drive and when you can cross a line, all commonly tested on the knowledge exam.

Center turn lane (CTSL)

Used only to begin or complete a left turn; not for ordinary through travel or merging.

Solid white line

Do not cross; marks the edge of the road or a lane that should not be changed.

Solid yellow line (your side)

No passing allowed.

Broken yellow line

Passing allowed when safe.

Solid + Broken yellow centerline

Passing allowed only on the broken-line side.

5. Passing in North Dakota: Treat Every Hill and Curve as if Traffic Is Coming: ND Rule

When is it illegal to pass another vehicle in North Dakota, and how close to an intersection can you pass? Passing is one of the most dangerous maneuvers on the road, North Dakota law sets strict distance and visibility rules:

• Only pass on the left, using the oncoming lane, when it is safe and legal.
• Do not drive left of center when approaching or on a hill crest or curve where your view is obstructed, within 100 feet of an intersection or railroad grade crossing, or when your view is obstructed within 100 feet of a bridge, viaduct, or tunnel. Obey posted no-passing zones.
• The vehicle being passed must not speed up while you are overtaking.
• Return to your lane before coming within 200 feet of oncoming traffic.
• When overtaking a bicyclist traveling in the same direction, leave at least 3 feet of clearance and maintain that clearance until safely past.
• Never pass a stopped school bus with flashing red lights, this applies in both directions on undivided roads.
• You may pass on the right only when North Dakota law permits and the movement can be made safely without driving off the roadway, including when the vehicle ahead is turning left or when the roadway has unobstructed pavement wide enough for two or more lawful lines of traffic in your direction.

6. ND Following Distance: 3-Second Rule on Open Prairie, At 55 MPH = 300 Feet to Stop

What is the safe following distance in North Dakota, and how does weather change it? North Dakota uses the 3-second rule as the minimum under normal conditions: pick a fixed object ahead, and when the car in front passes it, you should reach it no sooner than 3 seconds later.

7. ND School Bus Law: Separate-Roadway Exception, $100/6-Point Penalty & Move Over Rule

Do you have to stop for a school bus on a divided highway in North Dakota, and what is the fine for passing one illegally? These are two of the most frequently tested topics on the North Dakota permit exam.

School Buses

• When a school bus stops with flashing red lights and an extended stop arm, all traffic in both directions must stop on undivided roads.
• On a highway with separate roadways, a driver does not have to stop when the school bus is on a different roadway.
• A center turn lane does not create a separate roadway; if the bus is on the same roadway, drivers meeting or overtaking it must stop when its red lights or stop arm are actuated.
• You must remain stopped until the red lights stop flashing and the stop arm is retracted.
• Penalty for illegally overtaking or passing a stopped school bus in North Dakota: $100 statutory fee and 6 points on the driving record.
• Railroad crossings: School buses are among the vehicles required to stop within 15–50 feet of the nearest rail before crossing, except at crossings designated out of service or exempt, or when traffic is controlled by a police officer.

Emergency Vehicles

• When you see or hear an emergency vehicle (police, fire, ambulance) with lights or siren: pull to the right edge of the road and stop. Do not block intersections.
• Move Over Law (North Dakota): On the Interstate system or a multilane highway outside city limits, when a motor vehicle is stopped, standing, or parked with flashing hazard warning signals, move to a lane not adjacent to it when that can be done safely. If you cannot move over safely, proceed with due caution, reduce speed, and maintain a safe speed for road conditions.

8. ND DWI Laws: 0.08 BAC, 91-Day First Administrative Suspension & 24/7 Sobriety Program

What is the legal BAC limit in North Dakota for drivers under 21, and can you refuse a breathalyzer? North Dakota DWI laws cover every driver category with different limits and strict implied consent penalties.

9. ND Seat Belt Law: Under-8 Child Restraint, 57-Inch Exception & All-Seat Belt Rule

Who gets the ticket if a passenger is not wearing a seat belt in North Dakota, the driver or the passenger? North Dakota is a primary enforcement state, meaning officers can stop you solely for a seat belt violation.

10. ND Parking Rules: Park Within 1 Foot of Curb, 10-Foot Hydrant Rule & No-Park Zones

How far from a fire hydrant must you park in North Dakota, and is it legal to park on a bridge? These distance rules are frequently tested and easy to miss if you have not studied the specific numbers. Know where you cannot park:

• Within 10 feet of a fire hydrant
• On or within 10 feet of a crosswalk at an intersection
• Within 15 feet of a flashing beacon, stop sign, or traffic-control signal placed at the side of the roadway
• Within 15 feet of the nearest rail of a railroad crossing
• On a sidewalk, in front of a driveway, or on a bridge
• Where official signs prohibit stopping or parking
• Double parking (alongside a vehicle already parked at the curb)
• Headed downhill: turn wheels toward the curb. Headed uphill with a curb: turn wheels away from curb. Uphill without a curb: turn wheels toward the shoulder.

11. Driving in North Dakota Blizzards, Black Ice & Ground Blizzards: What the Manual Says

Are headlights required when it is raining in North Dakota, and what should you do if your car starts to hydroplane? North Dakota weather can change fast during blizzards, blowing snow, and icy prairie conditions; these rules tell you exactly how to adjust.

• Headlights required in North Dakota from sunset to sunrise and whenever visibility is less than 1,000 feet due to rain, snow, sleet, hail, smoke, or fog.
• In heavy fog, use low beams, high beams reflect off fog and reduce visibility.
• If you start to hydroplane, ease off the gas gently. Do not brake hard or turn sharply.
• In icy conditions, brake gently well in advance. Start slowing earlier than normal. Leave extra following distance.
• If your car goes into a skid, steer in the direction you want the front of the car to go. Do not overcorrect.
• It is illegal to enter a road officially closed because of hazardous conditions; the North Dakota statutory fee is $250.
• Studded snow tires may be used in North Dakota from October 15 through April 15.

12. ND Points: 12 = 7-Day Suspension, Each Point Above 11 Adds 7 More Days

How many points does a speeding ticket add to your North Dakota license, and at what point do you lose it? North Dakota uses a point system in which points are added after traffic violations and reduced over time when no new point violations are recorded; accumulating too many points leads to suspension or cancellation.

Note: Completing an approved driver-improvement or defensive-driving course can reduce your point total by 3 points, with this reduction available once every 12 months. One point is also reduced for each three-month period with no new point violation.

13. North Dakota Headlight Law: Dim 500 Feet Oncoming, 300 Following, 1,000-Foot Visibility Trigger

When must you dim your high beams in North Dakota, and how far away does an oncoming car need to be? North Dakota law specifies exact distances for dimming, and the 500/300-foot rule is one of the most tested questions on the exam.

Key test point: The 500-foot / 300-foot rule is a classic exam question. Oncoming = 500 feet. Following = 300 feet. Dim accordingly.

14. Night Driving in ND: Headlight Distance, Glare & Wildlife Hazards

What does "overdriving your headlights" mean in North Dakota, and why is it dangerous? Driving at night significantly increases crash risk; these rules cover visibility, speed, and wildlife hazards specific to North Dakota roads.

15. ND Distracted Driving: Texting = $100 Fine, Under-18 Electronic Device Restrictions

Is it legal to use your phone while driving in North Dakota, and can a cop pull you over just for texting? North Dakota has specific primary-enforcement laws targeting handheld device use, with stricter rules for permit and intermediate license holders.

Key test point: North Dakota's electronic-message prohibition applies while driving and during temporary stops in traffic, but not while the vehicle is lawfully parked.

16. ND Railroad Crossings: 15–50 Feet From Rail, 20 MPH Obstructed-View Rule

How far from the tracks must you stop at a railroad crossing in North Dakota, and what vehicles must always stop even when no train is coming? Railroad crossing rules are tested on the North Dakota knowledge exam; know exactly when to stop and how far back. When your view of the track is obstructed, the maximum is 20 mph when approaching the crossing unless otherwise posted.

Key test point: Never drive around or under a lowered crossing gate, it is illegal and extremely dangerous. Wait until gates are fully raised and all tracks are clear.

17. North Dakota Roundabouts: Yield on Entry, Lane Selection & Exit-Signal Rule

North Dakota has built roundabouts at intersections across Fargo, Bismarck, Grand Forks, and at rural highway junctions throughout the state. The NDDOT manual covers them. Entering traffic yields to vehicles already circulating inside, no exceptions.

Key test point: The most common wrong answer on roundabout questions is thinking you have right-of-way when entering. You never do, yield to traffic already inside.
