While online practice tests can help license applicants with the driver's knowledge test, practice questions do not appear on the actual written test. The sample tests provide a general idea of the type of questions that are asked on the knowledge test and outline the test format.
Official online practice tests are available on the Department of Motor Vehicles or Department of Transportation section of each individual state's government website.
The driver's knowledge test asks questions on a variety of driving safety topics, such as road signs, traffic laws and other information drivers need to know to operate a motor vehicle in the state. Consult your state's official driver's manual and refer to additional sample test questions for this information.
