North Dakota Permit Test Study Guide (2026)

Cover every topic on the North Dakota DMV permit test, ranked by how often they show up on the real exam.

The North Dakota Noncommercial Driver License Manual is published by NDDOT. It covers license types, road signs and signals, driving skills, emergency handling, and drinking and driving laws. The manual is available in English and Spanish as a free PDF. Read each chapter, take notes, and use practice tests to check what you remember.

North Dakota Speed Limits

Speed limits are one of the most-tested topics on the ND permit exam, and the questions usually test default limits — what the speed is when no sign is posted. Most states use a layered system: roughly 25 mph in residential and business districts, 15–25 mph in school zones during posted hours, 55–70 mph on rural highways, and up to 70–85 mph on interstates depending on the state. Always obey the basic-speed law: never drive faster than is safe for current conditions, even if you are under the posted limit. Rain, fog, snow, glare, and heavy traffic all require you to slow below the sign. Check the North Dakota driver manual for the exact default values used on the test.

Alcohol & BAC Limits

Expect at least one alcohol question on the North Dakota permit test. Memorize the three BAC thresholds used in nearly every state: 0.08% is the legal limit for drivers age 21 and older, 0.04% is the limit for anyone driving with a commercial driver license (CDL), and 0.02% or 0.0% applies to drivers under 21 under zero-tolerance laws. Driving with any measurable alcohol under 21 is a license suspension in most states. North Dakota also has an implied-consent law: by accepting your license, you have already agreed to a breath, blood, or urine test if an officer suspects you of impaired driving. Refusing the test triggers an automatic license suspension on top of any DUI charge.

Right-of-Way Rules

Right-of-way is the single most-missed topic across every state's permit test. The rules are simple once you memorize them. At a 4-way stop, the first vehicle to fully stop goes first; if two arrive together, the driver on the right has the right of way. At an uncontrolled intersection, yield to any vehicle already in the intersection and to the driver on your right. At roundabouts, yield to traffic already circulating and enter only when there is a safe gap. Always yield to pedestrians in any crosswalk, marked or unmarked, and to emergency vehicles with lights and sirens — pull right and stop. When turning left across oncoming traffic, you must yield to oncoming vehicles. Yield does not give you the right of way; it requires you to give it up.

Following Distance & Safety

The standard following distance taught in the North Dakota driver manual is the 3-second rule: pick a fixed point on the road, wait for the vehicle ahead of you to pass it, then count "one-thousand-one, one-thousand-two, one-thousand-three." If you reach the point before the count, you are too close. Push the count to 4 seconds in rain, 6 seconds on packed snow, and 10 seconds on ice. Also adjust when towing, when being tailgated (let them pass), and at highway speeds. Mirrors do not eliminate blind spots — always glance over your shoulder before changing lanes. Defensive driving means scanning 10–15 seconds ahead, leaving a cushion of space on all sides, and assuming other drivers will make mistakes.

Road Sign Colors & Shapes

Road signs on the ND permit test follow the federal Manual on Uniform Traffic Control Devices, so shapes and colors are consistent across the country. Memorize the shapes first: octagon always means stop, downward triangle means yield, diamond means warning, pentagon marks a school zone, round warns of a railroad crossing, and horizontal rectangle is a guide sign. Then learn the colors: red is stop or prohibition, yellow is general warning, orange is construction, green is directions and exits, blue is driver services, brown is recreation, and fluorescent yellow-green is for schools and pedestrians. Practice identifying signs by shape and color alone — see the full visual cheat sheet on our North Dakota road-signs page.

Key North Dakota Numbers to Memorize

If you only remember a handful of facts going into the test, make it these. Every one of them maps to questions that have appeared on the real ND exam.

Parking Rules

Parking questions on the North Dakota permit test cover three patterns. For parallel parking, your wheels should be no more than 12 inches from the curb. For hill parking, the kerb rule decides which way your front wheels point: facing downhill (with or without a curb), turn the wheels toward the curb; facing uphill with a curb, turn the wheels away from the curb so they rest against it; facing uphill with no curb, turn the wheels toward the edge of the road. Always set the parking brake and leave the car in park (or in low gear with a manual). No-parking zones you must memorize: within 15 feet of a fire hydrant, within 20 feet of a crosswalk, within 30 feet of a stop sign or signal, within 50 feet of a railroad crossing, and never in front of a driveway, on a sidewalk, or in a marked bus zone.

GDL Restrictions (ND)

Every state uses a Graduated Driver License (GDL) program to ease new teen drivers in step-by-step. The North Dakota rules vary in the exact numbers but follow the same pattern: a minimum age (14 in North Dakota) to apply for a learner permit, a required period of supervised practice driving (typically 30–50 hours, with at least 10 of those at night), a night-driving curfew for intermediate license holders (often 9 or 10 PM until 5 AM, with exceptions for work or school), and passenger limits that restrict the number of non-family teen passengers in the car. Cell-phone use is banned for all GDL drivers under 18, even hands-free, in most states. Expect 1–3 GDL questions on the ND exam — they are easy points if you read the GDL chapter of the manual.

DUI & Drug Laws

DUI questions go beyond the BAC limits in Section 2. Three concepts you must know: implied consent means refusing a chemical test triggers automatic license suspension on top of any DUI charge. Prescription and over-the-counter drugs can also impair driving — antihistamines, sleep aids, painkillers, and some cold medicines list "do not operate heavy machinery" warnings, and driving impaired by them is a DUI even if you have a valid prescription. Marijuana — even where state-legal — is treated like alcohol for driving: any detectable impairment can result in a DUI, and edibles can take 1–3 hours to peak. The only safe BAC and the only safe THC level for driving is zero. There is no quick way to sober up; only time will lower your BAC.
