This practice knowledge test will help you prepare for the DC DMV knowledge test. Studying the DC Driver Manual is a requirement for successfully passing the driver knowledge test. When you visit the DC DMV service center to take the actual driver knowledge test, there is a $10 fee for each driver knowledge test taken. The driver knowledge test is a computerized test with visual touch screen or audio touch screen (using headphones). If audio is your preference, please notify the DMV representative before starting the test. The questions on this practice test may or may not be on the actual driver knowledge test taken at the DC DMV. Remember to thoroughly study the DC Driver Manual prior to arriving at the DMV to take the test. A score of 80% or higher is required to pass the knowledge test. If you fail the knowledge test 6 times within a 12 month period, you will not be allowed to take the 7th test until 12 months after the 1st failed test.
