Residents must have an Oklahoma driver's license or learner's permit to operate a motor vehicle on any Oklahoma street or highway. You must pass both the vision screening and written test to be eligible for the driving test. The Oklahoma Driver's Manual will be used to create the questions for the OK DMV written test. You'll be quizzed on Oklahoma traffic laws, road rules, road signs, as well as safe driving practices. The Oklahoma DMV test has 25 questions, and you must answer at least 20 of them correctly to pass (80%). You must wait at least one day before retaking the knowledge test if you fail it. Practice with our Oklahoma permit test to familiarize yourself with the format of the Oklahoma driver's license test.
