The California DMV written test has 36 questions, and you must answer at least 30 correctly to pass

The California DMV written test, officially called the written knowledge test, contains exactly 36 multiple-choice questions. You need a score of at least 83 percent — which means 30 correct answers — to pass and move forward with your license. The test covers California traffic laws, road signs, safe driving practices, and what to do in emergencies.

You take this test at a DMV office on a computer or paper form, depending on which location you visit. The test is timed: you have up to three hours to complete it, though most people finish in 30 to 45 minutes. If you do not pass on your first attempt, you can retake it the same day or come back another time — there is no waiting period between attempts at most DMV offices.

What the test covers and where questions come from

Every question on the California written test comes from the California Driver Handbook, a free booklet the DMV publishes and updates regularly. The handbook is available online at the DMV website and in print at any DMV office. The test draws from five main areas: traffic laws and right-of-way rules, road signs and their meanings, safe driving practices, vehicle equipment and maintenance, and what to do if you are in an accident or emergency.

The DMV does not publish the exact questions in advance, but the handbook contains all the information you need to answer them. Questions are written in plain language and test whether you understand the rule, not whether you can guess. For example, a question might ask what you should do if your brakes fail on a hill, rather than asking you to define a technical term.

How the test is scored and what happens if you fail

The DMV scores your test when ready after you finish. You need 30 out of 36 correct answers to pass — that is a score of 83 percent. If you score 29 or lower, you fail and must retake the test. There is no penalty for retaking it: you can take it again the same day at most DMV offices, or you can schedule another appointment for a later date.

If you fail twice, some DMV offices require you to wait one day before your third attempt, though this varies by location. Call your local DMV office or check the website to confirm the retake policy where you plan to test. Each time you retake the test, you receive a new set of 36 questions drawn from the same pool of topics.

Preparing for the test: what to study and how

The best way to prepare is to read the California Driver Handbook from start to finish. The handbook is organized by topic and covers everything the test asks about. You can read it online, read it as a PDF, or pick up a printed copy at any DMV office. Set aside time to read it carefully — most people spend three to five hours reading the entire handbook.

After reading the handbook, take practice tests. The DMV website offers free practice tests that use real questions from the actual test pool. These practice tests are the single most useful study tool because they show you the exact format and difficulty level you will face. Many people take the practice test multiple times until they score 30 or higher consistently. You can also find practice tests through third-party websites, though the official DMV practice test is the most reliable.

Focus extra attention on road signs, because many test-takers struggle with them. The handbook includes a section with pictures of every sign you need to know. Spend time memorizing what each sign means and when you will see it on the road. Right-of-way rules are another common trouble spot — read that section twice and pay attention to the specific situations the handbook describes.

What to bring and what to expect on test day

Bring a valid form of identification to your DMV appointment. Acceptable forms include a passport, birth certificate, visa, or other government-issued ID. You will also need to bring proof of your Social Security number, such as a Social Security card or tax return. If you are under 18, bring a parent or guardian with you.

Arrive at least 15 minutes early. The DMV will check your documents, take your photo, and assign you to a computer or give you a paper test. You will sit at a desk or kiosk and answer the 36 questions one at a time. You cannot go back and change your answers once you move to the next question on a computer test, so read each question carefully before you select your answer. On a paper test, you can review and change answers before you turn it in.

You are not allowed to use a phone, notes, or any reference materials during the test. The DMV staff will watch to make sure you do not cheat. If you need the test in a language other than English, the DMV offers tests in Spanish and several other languages — request this when you schedule your appointment.

Scam alert: fake practice tests and study guides

Be careful about websites that claim to offer "the real DMV test questions" or "may provide pass" study materials. These are often scams designed to take your money or steal your personal information. The only official practice test is on the California DMV website at dmv.ca.gov. Use that one.

Do not pay for study guides or apps that claim to have the actual test questions — the DMV does not sell these, and no private company has access to the real test pool. Free or low-cost options like the official DMV handbook and practice test are all you need. If a website asks for payment to "unlock" test questions or promises you will pass if you buy their product, it is not legitimate.

Frequently Asked Questions

Can I take the written test in a language other than English?

Yes. The California DMV offers the written test in Spanish, Mandarin, Cantonese, Vietnamese, Korean, and Tagalog. You must request a test in another language when you schedule your appointment. Call your local DMV office or book online to let them know which language you need.

What if I fail the written test three times?

After three failed attempts, you must wait one day before taking the test again. Some DMV offices may require you to retake a behind-the-wheel driving test or complete additional training before you can test again — policies vary by location. Contact your local DMV office to find out what is required in your area.

Do I have to pass the written test before I take the driving test?

Yes. You must pass the written knowledge test before you can schedule a behind-the-wheel driving test. The written test comes first, and you receive a certificate or notice showing you passed. Bring this to your driving test appointment.

How long is the written test valid after I pass it?

Your passing score is valid for 12 months from the date you pass. During that time, you can schedule your behind-the-wheel driving test. If you do not take and pass the driving test within 12 months, you will need to retake the written test.

Can I use a dictionary or translator during the test?

No. You cannot use any reference materials, including dictionaries or translation devices, during the written test. If English is not your first language, request the test in your preferred language when you schedule your appointment instead.
