Frequently Asked Questions

In North Dakota, teens must follow the three steps of the Graduated Licensing Program to obtain a class D driver license:

For a learner’s permit, you must be at least 14 years old.
For an intermediate license, you must either hold the permit for one year or be 16 years old and have held the permit for at least six months.
For a standard license, you must be at least 16 years old and complete a road test.

You can visit a North Dakota driver license office or take the DMV written test at home using KnowTo Drive, the official knowledge testing platform. For this second option, if you are under 18, you must be supervised by a parent/legal guardian with a valid driver's license. After passing the exam, you are still required to visit the DOT to validate your identity and complete the testing process.

You'll need to bring the following documents:

Completed application (if you are under 18, a parent/legal guardian must sign your application and assume financial liability).
Proof of identification (if your name has changed, please provide proof of your current legal name).
Proof of Social Security Number.
Proof of North Dakota residence (two documents).

Use this checklist to ensure you have all the required documents before your appointment.

You can take the DMV written test in Arabic, Chinese, English, French, Nepali, Russian, Serbo-Croatian, Spanish, Somali, Swahili, Turkish, Vietnamese, Pashto, and Dari. Additionally, automated American Sign Language and audio testing are provided at the following offices: Fargo, Jamestown, Bismarck, Dickinson, Williston, Minot, Devils Lake, and Grand Forks.

To prepare for the DMV written test, you can refer to the official North Dakota Driver's Handbook. The manual covers various information about road signs, parallel parking, turning, passing a vehicle, yielding the right of way, etc. Study carefully the different sections and test your knowledge with our free practice tests!

The DMV written test has 25 questions, and you have 60 minutes to answer them. The questions cover different topics about road rules and safe driving practices.

You are allowed up to 5 wrong answers. This means that the passing score is 80%. It's important to stay focused during the exam and take the time to read the questions carefully to minimize errors and pass the DMV written test on the first attempt.

For new drivers in North Dakota, various restrictions apply:

With a learner's permit, you must drive under the supervision of a parent/guardian or an adult aged 18 or older who has a minimum of three years of driving experience, seated beside you.
With an intermediate license, if you are under 16, you can drive alone except between sunset or 9 p.m. and 5 a.m. or for work, school, and religious activities.

Additionally, all drivers under 21 are considered legally under the influence of alcohol if their blood alcohol content (BAC) is .02 or greater. For those under 18, using cell phones while driving is forbidden except during emergencies.

You must wait 24 hours before retaking the DMV written test after a failure. You have 5 attempts within a year, but each time you need to pay another fee. If you leave the testing area early before completing the exam or if you bring cell phones or electronic devices, you may be disqualified. Additionally, attempting to cheat during an online test will result in automatic failure.
