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

California's written knowledge test is a 36-question multiple-choice exam that you take at a DMV office on a computer. You need to answer at least 30 questions correctly to pass. The test covers California traffic laws, road signs, right-of-way rules, and safe driving habits — everything in the California Driver Handbook.

You take the test in English unless you request an interpreter or a translated version. California offers the test in multiple languages including Spanish, Chinese, Vietnamese, and others. If you need an interpreter, call your local DMV office ahead of time to arrange it.

The test itself takes about 10 to 20 minutes to complete once you sit down at the computer. You can take it as many times as you need, but you must wait 24 hours between attempts if you fail.

What topics the California test covers

The California Driver Handbook is your study guide. The test pulls questions from every section of it. You will see questions about speed limits, stopping at red lights and stop signs, right-of-way rules, parking, lane changes, and how to handle pedestrians and cyclists.

Road signs make up a significant portion of the test. You need to know what each sign means — not just recognize it. For example, you should know that a diamond-shaped yellow sign warns of a hazard ahead, and a red octagon means stop. The handbook includes a full section with pictures of signs and their meanings.

Expect questions about driving under the influence, distracted driving, seat belts, child safety seats, and what to do if you are pulled over by police. California also tests knowledge of special rules like how to drive around school buses, what to do at railroad crossings, and how to share the road with motorcycles and bicycles.

How the test is scored and what happens if you fail

The computer scores your test when ready after you finish. You will see your score before you leave the DMV office. If you pass, you move forward in the licensing process. If you fail, the DMV staff will tell you that you did not pass and explain that you can retake the test.

You must wait at least 24 hours before taking the test again. You can take it at the same DMV office or at a different one — there is no restriction on location. There is no limit to how many times you can retake the test, but each attempt requires a new fee (currently $10 for the knowledge test, though this may change).

Many people pass on their second or third attempt after spending more time studying the handbook. The test is designed to measure whether you know California traffic laws well enough to drive safely, not to trick you.

How to prepare for the California written test

The California Driver Handbook is free and available online at the DMV website (dmv.ca.gov) and in print at any DMV office. Read through the entire handbook at least once. Pay special attention to the sections on traffic signs, right-of-way, and speed limits, since these appear frequently on the test.

After you read the handbook, use the sample test questions that the DMV provides online. The sample test has 50 questions and mimics the format of the real test. Taking the sample test multiple times helps you get comfortable with the computer format and identify topics you need to review.

Study in short sessions over several days rather than cramming the night before. Focus on understanding the rules, not memorizing answers. If you do not understand why a particular rule exists, reread that section of the handbook.

What to bring and what to expect on test day

Bring a valid form of identification to the DMV office. Acceptable IDs include a passport, a birth certificate with a photo ID, a state ID from another state, or a visa with an I-94 form. You will also need your Social Security number or an Individual Taxpayer Identification Number (ITIN).

Arrive at least 15 minutes early. The DMV office will be busy, and you may need time to check in and wait for your turn. When you are called, DMV staff will verify your identity and take you to a computer terminal where you will take the test.

You cannot bring notes, phones, or study materials into the testing area. You also cannot leave the testing area and come back — once you start the test, you must finish it. The computer will not let you go back to previous questions, so answer each one before moving to the next.

Retaking the test at different DMV offices

If you fail the test, you can retake it at any DMV office in California. You do not have to go back to the same location. This is helpful if your local office is very busy or if you want to take the test at a different time of day.

Each DMV office has its own wait times and hours. You can check wait times online at dmv.ca.gov before you go. Some offices are much less crowded than others, so if your local office has a long wait, you might save time by driving to a nearby office in a smaller town.

What happens after you pass the written test

Once you pass the written test, you are cleared to take the behind-the-wheel driving test. You do not have to take the driving test when ready — you can schedule it whenever you are ready. However, if you are under 18, California has specific rules about when you can take the driving test based on how long you have held your permit.

Your passing score is valid for 12 months. If you do not take and pass the driving test within that year, you will need to retake the written test before you can schedule the driving test.

Frequently Asked Questions

Can I take the California written test online from home?

No. You must take the test in person at a DMV office on a computer provided by the DMV. You cannot take it remotely or on your own computer.

What happens if I run out of time while taking the test?

There is no time limit on the California written test. You can take as long as you need to answer all 36 questions. Most people finish in 10 to 20 minutes, but you are not rushed.

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

No. In California, you get a learner's permit first, then take the written knowledge test, then take the driving test. You must pass the written test before you can take the driving test, but not before you get the permit.

Can I use the California Driver Handbook in another language if English is not my first language?

Yes. The California Driver Handbook is available in Spanish, Chinese, Vietnamese, Korean, Tagalog, and other languages on the DMV website. You can also request the written test itself in another language when you schedule your appointment or when you arrive at the DMV office.

What is the passing score on the California written test?

You must answer at least 30 out of 36 questions correctly to pass. That is about an 83 percent score. The computer tells you when ready whether you passed or failed.
