The California DMV written test covers road rules, traffic signs, and safe driving practices specific to California law

The California DMV written test, officially called the knowledge test, is a multiple-choice exam you take before you can get a learner's permit or driver's license. The test has 36 questions, and you need to answer at least 30 correctly to pass. You answer on a computer at a DMV office, and results are available when ready after you finish.

The test draws from the California Driver Handbook, a free publication the DMV provides online and in print at every office. The handbook covers California-specific traffic laws, right-of-way rules, speed limits, parking regulations, and how to handle different road conditions. The test does not include a driving component — that comes later, after you pass the written test and practice with a learner's permit.

Key Takeaways

  • The knowledge test has 36 multiple-choice questions, and you must answer at least 30 correctly to pass.
  • You can take the test in English, Spanish, Mandarin, Cantonese, Vietnamese, or Korean at most California DMV offices.
  • The test covers only information in the California Driver Handbook, which is free to read or pick up at any DMV office.
  • You can retake the test the same day if you fail, though some offices may have limited appointment slots.

What topics appear on the California knowledge test

The test focuses on practical driving knowledge you need to stay safe and follow California law. Common topics include right-of-way rules at intersections and four-way stops, speed limits and how they change in different zones, parking rules and what different signs mean, and how to handle pedestrians and bicyclists. The test also covers seat belt and child safety seat laws, what to do at railroad crossings, and how to respond to emergency vehicles.

You will also see questions about alcohol and drug impairment, distracted driving, and what happens if you refuse a breath test. California has strict laws about these topics, and the DMV tests them heavily. Questions about weather and road conditions — how to drive on wet pavement, in fog, or on hills — also appear regularly. The test does not ask about vehicle maintenance or mechanical knowledge, only driving behavior and California traffic law.

How to prepare using the California Driver Handbook

The California Driver Handbook is the only official source for the test. You can read it as a PDF from the DMV website at dmv.ca.gov, or pick up a printed copy at any DMV office, library, or authorized service center. The handbook is organized by topic, so you can read it straight through or focus on sections where you feel less confident.

Many people read the handbook once, then use sample tests to identify weak areas and review those sections again. The DMV website offers a free sample test with 36 questions that mirrors the real test format and difficulty. Taking the sample test under timed conditions — you have 30 minutes on the real test — helps you know whether you are ready. If you score below 30 on the sample, go back to the handbook and reread the sections where you missed questions.

Test format and what happens on test day

You take the test on a computer at a DMV office. The test is untimed, but most people finish in 10 to 15 minutes. You read each question on the screen and select one of four answers using the mouse or keyboard. You can review your answers before you submit, so you can go back and change an answer if you change your mind.

When you finish, the computer scores your test when ready and tells you whether you passed. If you pass, you move forward in the licensing process — either toward getting your learner's permit or, if you already have one, toward scheduling a driving test. If you fail, you can retake the test the same day at most offices, though you may need to wait for the next available appointment slot. There is no fee to retake the test.

Language options and accessibility accommodations

California offers the knowledge test in six languages: English, Spanish, Mandarin, Cantonese, Vietnamese, and Korean. When you schedule your test appointment online or by phone, you select your language preference. Not every DMV office offers every language, so check which languages are available at your location before you book.

If you have a disability or medical condition that affects how you take tests, you can request accommodations. Common accommodations include extra time, a reader who reads questions aloud, or a separate testing room. You must request accommodations when you schedule your appointment, not on the day of the test. Contact your local DMV office or call 1-800-777-0133 to discuss what accommodations may be available.

Retaking the test if you do not pass

If you score below 30 out of 36, you have not passed and will need to retake the test. You can retake it the same day if an appointment slot is available, or you can schedule another appointment for a later date. There is no waiting period between attempts, and you can take the test as many times as you need.

Before you retake the test, spend time reviewing the sections of the Driver Handbook where you struggled. The DMV website shows you which questions you missed on the sample test, so use that feedback to guide your study. Many people pass on the second or third attempt after focusing their review on specific topics rather than rereading the entire handbook.

After you pass: next steps toward your license

Once you pass the knowledge test, your next step depends on your age and whether you already have a learner's permit. If you are under 18 and do not yet have a permit, you will receive a learner's permit that day. With a learner's permit, you can drive only with a licensed adult 25 or older in the front seat next to you. You must hold the permit for at least six months and practice driving before you can take the driving test.

If you are 18 or older, or if you already have a learner's permit and are ready for the driving test, you will schedule a behind-the-wheel test at a DMV office. The driving test takes about 20 minutes and covers basic vehicle control, turning, parking, and how you respond to traffic and pedestrians. You must bring your own vehicle, proof of insurance, and your learner's permit or ID to the driving test appointment.

Frequently Asked Questions

Can I use my phone or notes during the test?

No. You cannot bring any materials into the testing area — no phones, notes, or the Driver Handbook. The test is closed-book. You must rely on what you have learned from studying the handbook beforehand.

What happens if I fail the test twice?

You can retake the test as many times as you need. There is no limit on attempts and no waiting period between tries. Each time you take it, you pay no additional fee. Focus your study on the topics where you missed questions the previous time.

Is the sample test on the DMV website the same difficulty as the real test?

Yes. The sample test has the same number of questions, covers the same topics, and uses the same multiple-choice format as the real test. If you score 30 or higher on the sample test, you are likely ready for the real test.

Do I need to pass the knowledge test before I can get a learner's permit?

Yes. You must pass the knowledge test before the DMV will issue a learner's permit. The permit is your proof that you understand California traffic laws and are ready to practice driving with a licensed adult.

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

Yes. The test is available in Spanish, Mandarin, Cantonese, Vietnamese, and Korean at most California DMV offices. Select your language when you schedule your appointment. Not all offices offer all languages, so check availability at your location first.
