What the OK DMV is and how it works

According to Service Oklahoma, “The written exam is a 20-question test that will test you on Oklahoma traffic laws, road rules, road signs, and safe driving practices.”^[1]

Service Oklahoma's Class D Written Knowledge Test checks your understanding of Oklahoma traffic laws, road rules, road signs, and safe driving practices. It has 20 questions, and you must answer 15 correctly to pass, a score of 75%. Results are available immediately after you finish.

You can take the test online or in person. The online test requires a desktop or laptop; phones are not supported. The online option is English only. The supplied KnowToDrive Oklahoma FAQ lists a 60-minute time limit. Check Service Oklahoma's Written Test page and the KnowToDrive Oklahoma FAQ for official testing instructions before choosing your delivery option.

If you fail, you can try again after a 1-day wait. Attempts are unlimited, but you may take the online test a maximum of 2 times. After 2 online failures, further attempts must be in person. A $4 Service Oklahoma fee is collected in-office for each failed attempt.

These details describe the written test, not every requirement for obtaining a license. Consult Service Oklahoma's Learner Permit page for application requirements. If your learner permit has been expired over 3 years, Service Oklahoma requires you to retake the written and drive tests.

OK DMV content outline and where to practise each area

The content areas below are copied from the official OK DMV content outline published by Service Oklahoma. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through OK DMV questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: How far from an intersection must Oklahoma drivers signal before turning?

1. 50 feet
2. 100 feet
3. 150 feet
4. 200 feet

Answer: B. 100 feet

Explanation:

B is the supplied correct answer: 100 feet. The question asks for the minimum signaling distance before turning at an intersection. Under the rule stated in this practice item, 50 feet is too short. The 150-foot and 200-foot options exceed the stated minimum, so neither answers the minimum-distance question, even though both describe earlier signaling.

Remember the distinction between a required minimum and a distance that exceeds it. This is a site-written practice question, not a real exam question. The supplied official test facts do not verify this signaling rule, so check it against current official Oklahoma driving material before memorizing the distance.

Example 2

Question: When do Oklahoma vehicle registration renewals expire?

1. On the vehicle owner's birthday
2. On the last day of the registration month
3. On January 1st each year
4. On the anniversary of purchase date

Answer: B. On the last day of the registration month

Explanation:

B is the supplied answer: the last day of the registration month. Within this practice item, the owner's birthday, January 1st, and the purchase anniversary are distractors because none identifies the end of the registration month. However, the supplied official facts do not establish vehicle registration expiration rules. The existing explanation also adds a birth-month connection that those facts do not support.

Treat this item as needing verification before using it to plan a renewal. The general lesson is to distinguish vehicle registration from driver license renewal: the verified license renewal guidance on this page does not establish a registration deadline. Check official registration information for your vehicle.

Example 3

Question: If you need to visit the Oklahoma DMV on a weekend, which of the following statements is true?

1. All DMV offices are open on Saturdays.
2. Most DMV offices are closed on weekends.
3. DMV offices are open on Sundays only.
4. Some DMV offices are open 24/7.

Answer: B. Most DMV offices are closed on weekends.

Explanation:

B is the supplied answer: most offices are closed on weekends. The item contrasts that general statement with claims that all offices open Saturdays, offices open Sundays only, or some operate 24/7. None of those alternatives is supported by the supplied official facts. Those facts also do not establish how common weekend closures are, so this answer should not be treated as verified scheduling guidance.

The useful rule is to check the specific location's published hours before planning a visit. Do not infer an office's availability from this practice answer. This administrative question is separate from practice on road signs, safe driving, and traffic laws.

How to use these practice tests

Start with Service Oklahoma's official driving study material. Read a topic, then use the matching practice set to see whether you can apply it. Use Traffic Signs and Signals for sign recognition and Road Rules and Traffic Laws for rule-based driving scenarios.

For each missed answer, write down the rule you misunderstood. Return to the official material, then explain why the correct choice fits and why the alternatives do not. Revisit questions you answered by guessing as well as those you missed. If an explanation adds a claim you cannot verify, mark it for checking instead of memorizing it.

Keep administrative practice separate from written-test study. Use the registration, location, and renewal sets when those services are relevant to you. Before test day, check the official testing instructions, confirm your delivery option, and review the retake rules. If taking the online test, arrange access to a desktop or laptop.
