The Oklahoma Road Signs & Driver Knowledge Test is the written exam every new driver in the state must pass to move from a learner permit toward a full license. It's administered by Service Oklahoma, working in cooperation with the Oklahoma Department of Public Safety, and it's typically taken by teens and adult first-time applicants alike.
Overview
The knowledge test is a single 20-question exam covering Oklahoma traffic laws, road rules, road signs, and safe driving practices — there's no separate, standalone signs-only section to schedule. Road sign recognition is woven into the same test as rules-of-the-road and safe-driving questions, so studying them together is the most efficient approach.
- Traffic laws and right-of-way rules
- Road sign meanings and shapes
- Safe driving practices
The official study reference is the Oklahoma Driver Manual, which covers all three areas in one handbook.
Cost and registration
Printing and issuing a Learner Permit costs $42.50. The knowledge test itself online carries no separate fee to sit for it, but each failed online attempt adds a $4 fee that becomes due when the permit is issued.
Exam format
The test consists of 20 questions with a 60-minute time limit. To pass, you must answer at least 15 of the 20 questions correctly — a 75% score. Applicants get two online attempts; after two fails, an in-person retest at a Service Oklahoma location or licensed operator is required.
Frequently asked questions
How many questions are on the Oklahoma written knowledge test and how much time do I get?
The test has 20 questions, and you're given 60 minutes to complete it. That's a generous window for a 20-question test, so time pressure typically isn't the challenge.
What is the passing score for the Oklahoma driver knowledge test?
You need to answer at least 15 of the 20 questions correctly, which is 75%. Falling below that means you'll need to retest.
What fees are involved in getting an Oklahoma learner permit and taking the test?
Printing and issuing the Learner Permit costs $42.50. If you fail the online knowledge test, a $4 fee is added for every failed attempt, due when the permit is issued.
What is the minimum age to get a learner permit in Oklahoma?
You can apply at age 15, provided you're enrolled and receiving instruction in an approved Service Oklahoma Driver Education course. Younger applicants outside that program should check the official requirements for their situation.
What are the supervised driving rules for a permit holder in Oklahoma?
Permit holders may drive between 5:00 a.m. and 10:00 p.m. only when accompanied by a licensed driver who is at least 21 years old. Driving outside that window or without a qualifying supervisor isn't permitted.
What happens if I fail the Oklahoma knowledge test, and can I retake it?
You get two online attempts; after two fails, you must go in person for further attempts. Each failed attempt adds a $4 fee that's due when your permit is issued.
