The Oklahoma knowledge (permit) test
Before you can get a learner permit, or a license if you are 18 or older, you must show Service Oklahoma that you know the rules of the road. The written knowledge test checks your understanding of traffic laws, road signs, safe driving and the effects of alcohol and drugs.
Oklahoma lets most people take this test online from home, which is convenient but comes with strict rules about equipment and identity checks.

What the test covers
Questions come from the Oklahoma Driver Manual. Expect questions on traffic laws, the meaning of signs, signals and pavement markings, right-of-way, speed, following distance, sharing the road and Oklahoma's alcohol and drug laws, including zero tolerance for drivers under 21. The manual also suggests learning any local traffic rules in your own city or town.
Taking it online, step by step
- Register online and pick the Class D test type, then read and accept the rules.
- Take the two photos the system asks for. The second is used to check it is still you throughout the test, so keep your face clear and do not add or remove glasses.
- Enter your details and answer the identity questions. If you are under 18, an adult must be present for this part.
- Start the test in a quiet room. You have 60 minutes, and results appear as soon as you finish.
- If you pass, visit a Service Oklahoma office or Licensed Operator to apply for your permit.
If it does not go your way
There is no extra charge for testing online, but each fail adds $4 to your eventual issuance fee. Service Oklahoma suggests trying again the next day, and the manual states you must wait at least one day before retesting. After two online fails, further attempts must be taken in person. A completion certificate from approved driver education can let Service Oklahoma waive the written test, but parent-taught driver education does not count for this waiver. For extra practice, our Oklahoma permit practice test pages offer two free 20-question sets.
Common mistakes
- Trying to take the online test on a phone or tablet. Only a computer with a webcam and microphone works.
- Testing in a noisy room or with someone talking. The test is monitored, and interruptions can cause problems.
- Memorizing practice answers instead of reading the manual. Real questions are worded differently.
- Skipping the alcohol and drug chapter. Oklahoma includes these laws in the test.
