Requirements by age

Under 18

  • You must be at least 15½ years old.
  • Bring a certificate of completion or enrollment in driver education.
  • A parent or guardian must sign your application. If parents share joint custody, both must sign.
  • You can take the knowledge test online at home, with a parent or guardian's consent. You need a computer with a webcam (not a tablet or phone). The online test is available Monday to Friday, 8 a.m. to 4 p.m., and you get two online attempts. After that, the third attempt is at a DMV office.
  • If you fail, you must wait seven days before retaking the test, not counting the day you failed.

18 and older

  • Driver education is not required if you are 18 or older.
  • You take the knowledge test at a DMV office. Tests are not given after 4:30 p.m.

Taking the test

  • You get three attempts to pass the knowledge test before you must reapply.
  • You also pass a vision exam and have your photo taken.
  • Testing aids such as the driver's handbook or a phone are not allowed during the test.
  • The application fee is non-refundable. See the DMV's licensing fees page for the current amount.

What the test covers

Questions come from the official California driver handbook: road signs and markings, right-of-way, speed and following distance, safe driving habits, and alcohol and drug laws. Our course covers it in 34 video lessons. These are free on the website:
