Is the California DMV Test an Open-Book Test?

Open-book exams allow you to take notes, texts, or resource materials into an exam situation, but the California knowledge test is not an open-book exam. All use of testing aids is strictly prohibited. This includes, but is not limited to the California Driver Handbook, cheat sheets, and/or electronic communication devices such as a cell phone, hand-held computer, etc.

Turn off your phone and don’t try to take pictures of exam questions with your phone!

If you are caught using your phone or any testing aid during the knowledge test, not only will your test be marked as a failure, but DMV may also act and postpone your possibilities of earning a driving privilege.

What Happens if You Fail the Test?

If you fail the California DMV test you must wait 7 days before you can try to pass exam again.

A re-test may also be subject to availability, which means you might have to wait longer.

To avoid this, you should prepare well to be able to pass the first time.
