Through the Department of Motor Vehicles, you can get a booklet to study for your written exam. The multiple choice written exam covers traffic signs, motor vehicle laws and safe driving techniques. All 10  traffic sign questions in Part One must be answered correctly before you can take the general knowledge exam in Part Two. You must score at least 80% on these questions to pass so be sure to study carefully. If you fail the written test, you must wait 15 days to take the test again and you may have to pay an additional fee to be retested.
