The written test has 36 questions in California

California's written knowledge test for a driver's license contains 36 multiple-choice questions. You must answer at least 30 of them correctly to pass — that's a score of about 83 percent. The test covers California traffic laws, road signs, safe driving practices, and what to do in different driving situations.

The questions come from the California Driver Handbook, which the Department of Motor Vehicles publishes free online and at every DMV office. Every question on the test appears in that handbook or in the sample tests the DMV provides. There are no trick questions or material outside the handbook.

You take the written test at a DMV office on a computer or on paper, depending on which location you visit. The test is offered in multiple languages, including English, Spanish, Chinese, Vietnamese, and others. You have up to one hour to complete it, though most people finish in 10 to 20 minutes.

  • All test questions come directly from the California Driver Handbook, which is free to read or pick up at any DMV office.

  • You take the test on a computer or paper at your local DMV office and have up to one hour to finish.

What the test covers

The 36 questions test your knowledge of California traffic laws and safe driving. Topics include speed limits and when they change, right-of-way rules at intersections and roundabouts, what different road signs mean, how to handle pedestrians and bicyclists, parking rules, and what to do if you're pulled over or in an accident.

The test also includes questions about vehicle equipment — things like headlights, turn signals, and mirrors — and questions about impaired driving, distracted driving, and sharing the road with large trucks. A few questions cover what to do in emergencies, like brake failure or a tire blowout.

Because California has specific rules about things like carpool lanes, chain requirements in mountain areas, and how to handle wildfires or air quality alerts, some questions may cover those topics too. The exact mix of questions varies slightly from test to test, but the DMV draws from the same pool of questions each time.

How to prepare with practice tests

The DMV publishes official sample tests on its website at dmv.ca.gov. These are real questions from the actual test pool, so practicing with them is the most accurate way to get ready. You can take the sample tests online for free, and they show you which questions you missed so you know what to study more.

Start by reading through the California Driver Handbook — it's about 50 pages and covers everything the test asks about. Then take a practice test to see which topics need more work. Go back to the handbook, read those sections again, and take another practice test. Most people who study this way pass on their first try.

You can also find practice tests through third-party websites and apps, but stick with the official DMV sample tests as your main study tool. They match the real test most closely and are free.

What happens if you fail

If you score below 30 out of 36, you fail and must wait before retaking the test. In California, you can retake the written test the same day at most DMV offices, though some locations may require you to wait a few hours or come back another day. There is no additional fee to retake it — you pay once when you first explore for your permit or license.

You can take the test as many times as you need until you pass. Most people who fail study the handbook more carefully and pass on their second or third attempt. There is no limit to how many times you can retake it.

Taking the test on the day of your appointment

Bring your appointment confirmation, a valid ID, and proof of your Social Security number or ITIN. At the DMV office, staff will check you in and take you to a computer or give you a paper test. You'll be in a quiet testing area where you can focus without distractions.

Read each question carefully. Some questions ask what you should do, and some ask what you should not do — make sure you understand which one before you answer. If you're unsure about a question, you can skip it and come back to it before you submit your test.

Once you submit your test, you'll get your score right away. If you pass, you move on to the driving test (if you're getting your first license) or you're done (if you're renewing). If you fail, ask the DMV staff when you can retake it.

Differences between the written test and the driving test

The written test and the driving test are separate. The written test checks what you know about traffic laws and road signs. The driving test checks whether you can actually drive safely — the examiner watches you handle the car, follow directions, park, and respond to traffic situations.

You must pass the written test before you can take the driving test. If you're renewing your license and haven't had any serious violations, you may not need to take either test — you can renew by mail or online instead.

Special testing accommodations

If you have a disability or a condition that makes it hard to take the standard test, the DMV can provide accommodations. These include extra time, a reader to read questions aloud, a larger print version, or a test in a different language. You need to request accommodations when you schedule your appointment or when you arrive at the DMV.

The DMV also offers the test in many languages besides English. If English is not your first language, you can take the test in Spanish, Chinese, Vietnamese, Korean, Tagalog, Japanese, Russian, Arabic, Hindi, Hmong, or Cambodian, depending on your location.

Frequently Asked Questions

Can I use my phone or notes during the test?

No. You cannot bring any materials into the testing area except your ID and appointment confirmation. You cannot use your phone, notes, or the handbook during the test. The DMV monitors the testing area to make sure everyone follows the rules.

How long does the written test take?

Most people finish in 10 to 20 minutes, but you have up to one hour. There is no penalty for taking your time — go at your own pace and read each question carefully before you answer.

What if I don't speak English well?

The DMV offers the test in 11 languages. Call your local DMV office or check the website to see which languages are available in your area. You can request a specific language when you schedule your appointment.

Do I have to memorize the handbook to pass?

You don't need to memorize it word-for-word, but you do need to understand the main points. Read through the handbook, take the practice tests, and focus on the topics where you score lowest. Most people who read the handbook once and practice with sample tests pass easily.

What if I pass the written test but fail the driving test?

Your written test score stays valid. You only need to retake the driving test, not the written test. You can schedule another driving test appointment as soon as you're ready.
