Save this confirmation — you will need to show it when you arrive at the DMV office. If you do not receive a confirmation within a few minutes, check your spam folder or try booking again.

Online booking is open 24 hours a day, and you can schedule an appointment up to several weeks ahead, depending on how busy your local DMV office is. Peak times (early morning, lunch hours, and late afternoon on weekdays) fill up faster than mid-morning or mid-afternoon slots.

Booking by phone if the website is not working

If you cannot book online, call 1-800-777-0133. Have your ID number and date of birth ready. A DMV representative will ask which service you need (knowledge test), your preferred location, and your availability. They will give you a confirmation number over the phone and may email or mail a confirmation to you as well.

Phone lines are busiest on Monday mornings and Friday afternoons. Calling early in the week or mid-morning usually means shorter wait times. The DMV phone system can take 15 to 45 minutes to reach a representative, depending on call volume.

What to bring to your appointment

Bring your appointment confirmation (printed or on your phone), a valid government-issued ID, and proof of California residency. Valid IDs include a current driver's license, passport, military ID, or state ID card. Proof of residency can be a utility bill, lease agreement, bank statement, or insurance document dated within the last 60 days and showing your name and address.

Do not bring study materials, phones, or other devices into the testing room. The DMV provides scratch paper and a pencil for notes during the test. Arrive 10 to 15 minutes early to allow time for check-in, even though you have a reserved time slot.

What happens if you miss or need to reschedule

If you cannot make your appointment, reschedule as soon as you know. Go back to dmv.ca.gov, select "Appointments," and choose "Reschedule Appointment." Enter your confirmation number and ID information. You can pick a new date and time without penalty. Rescheduling is free and does not affect your place in the system.

If you miss your appointment without rescheduling, you lose that slot and must book a new one. Missing an appointment does not disqualify you from taking the test — you straightforward need to schedule again. Some DMV offices may have a waiting period before you can book another appointment if you miss multiple times, though this varies by location.

The handbook covers everything on the test: traffic laws, right-of-way rules, parking regulations, and what different road signs mean. Most people study for a few hours to a few days before the test.

The test is given on a computer at the DMV office. You read each question on screen and select your answer using the mouse or keyboard. The system tells you when ready whether you passed or failed. If you pass, you receive a printed result sheet that day. If you fail, you can reschedule and take the test again, usually within a few days or weeks depending on appointment availability.
