What Oklahoma's written test covers and how it works
Oklahoma's written knowledge test is a computer-based exam administered at any Oklahoma Department of Public Safety (DPS) office. The test has 50 questions, and you must answer at least 40 correctly to pass — that is an 80 percent score. The questions come from the Oklahoma Driver's Manual and cover traffic laws, road signs, safe driving practices, and right-of-way rules specific to Oklahoma roads.
You take the test on a computer terminal at the DPS office during your appointment. The test is untimed, so you can take as long as you need to read each question and select your answer. Once you submit your final answer on the last question, the computer when ready tells you whether you passed or failed and shows your score.
If you fail, you can retake the test the same day or schedule another appointment. There is no waiting period between attempts in Oklahoma, though you will pay the test fee again for each retake.
Key Takeaways
- Oklahoma's written test has 50 questions and you need 40 correct to pass; it is taken on a computer at a DPS office.
- The Oklahoma Driver's Manual is the only source material you need to study, and the DPS provides a free PDF version online.
- You can retake the test the same day if you fail, but you will pay the test fee again for each attempt.
- Common mistakes include misreading right-of-way rules, confusing speed limit signs with other regulatory signs, and not knowing Oklahoma-specific laws like the hands-free phone requirement.
Where to find the Oklahoma Driver's Manual and what to study
The Oklahoma Department of Public Safety publishes the official Driver's Manual online at ok.gov/dps under the "Driver License" section. You can read it on screen or read the PDF for free. This manual is the complete source for all test questions — nothing on the test comes from outside this document.
The manual is organized by topic: traffic signs and their meanings, right-of-way rules, speed limits and traffic laws, parking rules, driving under the influence, and safe driving practices. Each section includes diagrams of road signs and explanations of what they mean. Pay special attention to the sections on right-of-way at intersections, yield signs versus stop signs, and pedestrian rules, because these topics appear frequently on the test.
Oklahoma-specific rules that catch many test-takers include the requirement to use hands-free devices for phone calls while driving, the rule that you must turn on your headlights 30 minutes after sunset, and the law that you cannot use the left lane on a four-lane highway except to pass. Read these sections twice.
How to prepare and what practice tests show you
The DPS does not publish an official practice test, but several third-party websites offer Oklahoma-specific practice tests that use questions in the same format and difficulty as the real exam. These practice tests help you get used to the computer interface and identify which topics you need to review more. Take at least two or three practice tests before your appointment, and review the manual again for any questions you miss.
Practice tests are most useful when you score below 85 percent, because that tells you which sections of the manual need more study time. If you score 90 percent or higher on practice tests, you are likely ready for the real test. Do not rely on memorizing practice questions — the real test uses different questions, so focus on understanding the rules and sign meanings instead.
Study in short sessions over several days rather than cramming the night before. Your brain retains information better when you spread learning across time, and you will feel more confident on test day.
What to bring to your DPS office appointment
Bring your completed DL 44 process form, a valid form of identification (passport, birth certificate, or state ID), and proof of your Social Security number (Social Security card or tax return). You will also need proof of Oklahoma residency, such as a utility bill, lease agreement, or bank statement dated within the last 30 days and showing your name and current address.
Bring your learner's permit if you already have one. If you are under 18, bring a parent or guardian with a valid ID. Arrive 10 to 15 minutes early to allow time for check-in, and bring any glasses or contacts you normally wear while driving — you must wear them during the test if you wear them while driving.
Do not bring your phone into the testing area. The DPS prohibits phones and other electronic devices during the test to prevent cheating. Leave your phone in your car or with someone outside the office.
Common mistakes and how to avoid them
The most frequent error is confusing right-of-way rules at four-way stops. The rule is straightforward: if two vehicles arrive at the same time, the one on the right has the right of way. Many test-takers overthink this and choose wrong. Read the right-of-way section of the manual three times and draw diagrams if it helps you visualize the scenarios.
Another common mistake is misidentifying speed limit signs. A white rectangular sign with black numbers is a speed limit sign. A yellow diamond is a warning sign. A red octagon is a stop sign. These look different, but test questions sometimes show them in quick succession to see if you are paying attention. Study the sign section with the actual images from the manual.
Test-takers also often miss questions about what to do when you see a school bus with red lights flashing. In Oklahoma, you must stop at least 15 feet away from the bus, whether you are behind it or approaching it from the front, and you cannot pass until the lights stop flashing. This rule appears on nearly every Oklahoma test.
What happens after you pass
Once you pass the written test, the DPS will schedule you for the driving skills test (also called the road test). This usually happens within two to four weeks, depending on how busy your local DPS office is. You will receive a notice in the mail with your appointment date, time, and location.
Your passing score on the written test is valid for 12 months. If you do not complete your road test within that year, you will have to retake the written test. Some DPS offices allow you to schedule your road test on the same day as your written test if space is available, so ask the staff before you leave.
Retaking the test if you do not pass
If you score below 80 percent, you will see your score and which question categories you missed. Write down the topics where you had the most trouble — usually the DPS computer shows you this information on screen. Go home, review those sections of the manual, and take another practice test focused on those topics.
You can retake the test when ready at the same DPS office if you want, or you can schedule a new appointment for another day. Many people find it helpful to wait a day or two and study more before retrying, because fatigue and test anxiety can affect your first attempt. There is no penalty for retaking the test, and you can take it as many times as you need.
If you fail more than three times, consider working with a driving school or instructor. They can identify gaps in your understanding that you might miss on your own and can teach you in a way that works better for your learning style.
Frequently Asked Questions
Can I take the written test in a language other than English?
Yes. Oklahoma DPS offices offer the written test in Spanish and several other languages. Call your local DPS office at least one week before your appointment to request a test in another language, because not all offices have interpreters available every day.
What is the fee for the written test?
The fee varies depending on your age and license type. Contact your local Oklahoma DPS office or visit ok.gov/dps for the current fee schedule, as fees change periodically and differ for Class D licenses, commercial licenses, and other categories.
Do I have to pass the written test before I can take the road test?
Yes. You must pass the written knowledge test before the DPS will schedule you for the driving skills test. The written test must be passed first, regardless of your age or license type.
What if I wear glasses or contacts while driving?
You must wear them during the written test if you wear them while driving. The test is designed to measure your knowledge, not your vision, but the DPS wants to may support you take the test under the same conditions you will drive under. Bring your glasses or contacts with you to your appointment.
How long does the written test take?
Most people finish between 20 and 45 minutes, though the test is untimed and you can take longer if you need to. The computer does not rush you, and you can review your answers before submitting if you want to double-check your work.
