How the California DMV written test works
The California DMV written knowledge test is a multiple-choice exam you take at a DMV office on a computer or paper form. You answer 36 questions about traffic laws, road signs, and safe driving practices. You need to score at least 30 correct answers (83%) to pass. The test is based on the California Driver Handbook, which the DMV publishes free online and in print at any DMV office.
You can take the test in English or one of several other languages, including Spanish, Chinese, Vietnamese, and Korean. If you need extra time due to a disability, you can request accommodations when you schedule your appointment or arrive at the office. The test itself takes most people 20 to 30 minutes.
You get your results when ready after finishing. If you pass, you move forward in the licensing process. If you fail, you can retake it the same day at most offices, though some locations may require you to wait or return another day. Each attempt costs the same fee as your original test.

What topics appear on the California test
The California DMV test draws all its questions from the California Driver Handbook. The handbook covers right-of-way rules, speed limits, parking laws, traffic signals and signs, seat belt and child safety seat requirements, and what to do at accident scenes. It also includes questions about impaired driving, distracted driving, and how drugs and alcohol affect your ability to drive safely.
Road signs make up a significant portion of the test. You will see pictures of common signs — stop signs, yield signs, warning signs, and informational signs — and choose what each one means. The handbook includes a full section with images and explanations of every sign you need to know.
Questions also cover vehicle equipment and maintenance: when your headlights must be on, what to do if your brakes fail, and how to check your mirrors. A smaller number of questions ask about sharing the road with bicycles, motorcycles, and large trucks, and how to respond to emergency vehicles.
How to prepare using the California Driver Handbook
The California Driver Handbook is the only official source for test content. You can read it as a PDF from the California DMV website (dmv.ca.gov), or pick up a printed copy at any DMV office, library, or highway patrol office. Reading the entire handbook takes most people two to four hours.
The handbook is organized by topic, so you can focus on areas where you feel less confident. Many people find it helpful to read a section, then write down the key points in their own words. Others use flashcards for road signs or create a study sheet of rules they find confusing.
The DMV website also offers a practice test that mimics the real exam. Taking the practice test more than once helps you get used to the format and timing. Some people take it once to see which topics they need to study more, then read those sections in the handbook, then take the practice test again.
When and where to take the test in California
You take the written test at a California DMV office. You must schedule an appointment online at dmv.ca.gov or by phone at 1-800-777-0133. Walk-in testing is not available at most locations, though a few offices may accept walk-ins on a limited basis — call ahead to check.
Appointment availability varies by location and time of year. Urban DMV offices often have longer wait times than rural ones. If your local office is booked out several weeks, you can search for appointments at nearby offices or try scheduling for an earlier time of day, which often has more openings.
You must bring your current ID and proof of your Social Security number (such as a Social Security card, W-2, or tax return). If you are under 18, you also need a parent or guardian present. Bring any documents related to your name change if your ID does not match your current legal name.
What happens if you fail the test
If you score below 30 correct answers, you fail and do not receive your permit or license. You can retake the test when ready at most DMV offices — you pay the test fee again and take it right away, either on the same computer or on paper. Some offices may ask you to return on a different day or schedule a new appointment, so ask the staff what your options are.
There is no limit to how many times you can retake the test in California. However, each attempt costs money, and repeated failures may delay your path to getting licensed. If you fail twice, spend extra time studying the handbook and consider taking the practice test several more times before your next attempt.
If you fail the test, you do not lose your learner's permit or any progress you have already made. You straightforward need to pass the written test before you can move to the behind-the-wheel driving test.
Test accommodations and language options
The DMV offers the written test in English, Spanish, Chinese (Mandarin and Cantonese), Vietnamese, Korean, Tagalog, Japanese, and Russian. When you schedule your appointment online or by phone, you can select your preferred language. If you do not see your language listed, call 1-800-777-0133 to ask about other options.
If you have a disability that affects your ability to take the test, you can request accommodations such as extra time, a larger font, or a reader to read questions aloud. Request accommodations when you schedule your appointment, or call the DMV at least five business days before your test date. The DMV will ask you to provide documentation of your disability, such as a letter from a doctor or a copy of an existing accommodation plan from school or work.
Common accommodations include 1.5 times or double the standard time, a separate testing room with fewer distractions, or a magnifying device. The DMV aims to provide accommodations that let you show what you know without changing the test itself.
Frequently Asked Questions
Can I bring notes or study materials into the testing room?
No. You cannot bring the handbook, flashcards, notes, or any other study materials into the testing room. You also cannot use your phone or any electronic device except the computer provided by the DMV to take the test. The DMV staff will ask you to put your phone away before you enter.
What if I do not pass the written test on my first try?

How long is the California written test valid if I pass?
Once you pass the written test, you have your learner's permit. The permit is valid for 12 months. During that time, you must pass the behind-the-wheel driving test to get your full license. If your permit expires before you pass the driving test, you must retake the written test.
Is the practice test on the DMV website exactly like the real test?
The practice test covers the same topics and uses the same multiple-choice format as the real test. However, the actual test questions are different from the practice test.

What if I need the test in a language not listed on the DMV website?
