What the California written test covers and how it is scored
California's written knowledge test for a driver license consists of 36 multiple-choice questions drawn from the California Driver Handbook. You must answer at least 30 questions correctly to pass — that is a score of 83 percent or higher. The test covers traffic laws, road signs, safe driving practices, and situations you will encounter on California roads.
The test is administered on a computer at your local Department of Motor Vehicles (DMV) office. You will have one hour to complete it. The questions appear one at a time on the screen, and you cannot go back to review or change your answers once you move forward. If you do not pass on your first attempt, you can retake the test, but you must wait at least one day before trying again.
The DMV does not publish the exact questions in advance, but the test is always based on material in the current California Driver Handbook. This handbook is free and available both in print at any DMV office and online at the California DMV website.

How to prepare using the California Driver Handbook
The California Driver Handbook is the official source for all written test content. It covers eight main topics: getting your license, traffic laws, safe driving practices, sharing the road, special driving situations, vehicle equipment and maintenance, parking, and driving under the influence. You should read the entire handbook at least once before taking the test.
Focus especially on sections about right-of-way rules, speed limits, stopping distances, traffic signals and signs, and what to do at intersections. These topics appear frequently on the test. The handbook also includes a sample test with 50 questions that mirrors the format and difficulty of the real test. Take this sample test under timed conditions — give yourself one hour — to see which areas need more study.
The handbook is available in print at any DMV office at no cost. You can also read it as a PDF from the California DMV website or read it online. If you prefer a physical copy, ask for it when you visit the DMV to schedule your test appointment.
Common mistakes test-takers make
Many people fail the California written test because they do not read questions carefully. The test often includes trick questions where two answers seem correct, but only one matches California law exactly. Read each question twice before selecting your answer, and pay close attention to words like "not," "always," "never," and "except."
Another frequent mistake is relying on driving experience instead of the handbook. California traffic laws may differ from laws in other states, and the test asks about California rules specifically. Even experienced drivers who learned to drive elsewhere often miss questions about California-specific rules like the "three-second rule" for following distance or California's mandatory seatbelt laws.
Some test-takers run out of time because they spend too long on difficult questions. If you are unsure about an answer, make your best guess and move on. You have about one minute per question on average, so do not get stuck. You can also skip questions and come back to them later on the computer — the system allows you to review unanswered questions before you submit your test.
What happens if you fail and need to retake the test
If you do not pass, you will receive a score report showing which topics gave you trouble. The DMV will tell you which sections of the handbook to review before your next attempt. You must wait at least one day before retaking the test, but there is no maximum number of retakes allowed.
Each time you retake the test, you will pay the test fee again. As of 2025, the written test fee is $10 for applicants under 18 and $10 for applicants 18 and older, though fees can change. You do not need to reschedule your entire license process — you only need to return to the DMV to take the test again.
If you fail three times, some DMV offices may require you to take a driver training course before attempting the test again, though this requirement varies by location. Contact your local DMV office to confirm their specific policy if you have failed twice already.
Test accommodations for people with disabilities or language barriers
If you have a disability that affects your ability to take the test, the DMV offers accommodations. These include extra time (up to one and a half times the standard hour), a reader to read questions aloud, a scribe to record your answers, or a magnifying device if you have vision problems. You must request accommodations when you schedule your test appointment, and you will need to provide documentation of your disability.
The DMV also offers the written test in multiple languages. Available languages include Spanish, Chinese (Mandarin and Cantonese), Vietnamese, Korean, Tagalog, Japanese, Russian, Arabic, Hmong, and others. The language available depends on your local DMV office. When you schedule your appointment, tell the DMV which language you need, and they will confirm whether it is available at your location.
If your preferred language is not available at your local office, you may be able to take the test at a different DMV location that offers it, or you can request a certified interpreter. Contact your DMV office at least two weeks before your planned test date to arrange either option.
Scheduling your test appointment and what to bring
You must schedule your written test appointment in advance. You can book an appointment online through the California DMV website, by phone at 1-800-777-0133, or in person at your local DMV office. Online scheduling is usually the fastest option and allows you to choose your preferred date and time.
When you arrive for your test, bring your valid identification document. Acceptable documents include a passport, a state ID card, a military ID, or a tribal ID. You will also need to bring proof of your Social Security number, such as a Social Security card or a tax return. If you do not have these documents, contact your DMV office before your appointment to find out what alternatives are accepted.
Arrive at least 15 minutes early. The DMV will verify your identity, check that you meet the age and residency requirements for a California driver license, and then direct you to a computer station to take the test. You will not be allowed to bring study materials, phones, or other devices into the testing area.
What to expect after you pass the written test
Once you pass the written test, you will move forward in the license process process. If you are under 18, you will need to complete a driver training course and hold a permit for a certain period before you can take the behind-the-wheel driving test. If you are 18 or older, you can schedule your driving test when ready after passing the written test.
The DMV will give you a receipt showing that you passed the written test. Keep this receipt — you will need it when you schedule your driving test appointment. The passing score is valid for 12 months, so you have one year to complete the rest of the license process. If you do not pass the driving test within that year, you will need to retake the written test as well.
After you pass both the written and driving tests, the DMV will issue your California driver license. You can choose to receive it by mail or pick it up in person at the DMV office. A standard driver license is valid for five years from the date it is issued.
Frequently Asked Questions
Can I use my phone or notes during the written test?
No. You cannot bring any study materials, phones, smartwatches, or other devices into the testing area. The DMV will ask you to leave these items outside the testing room or in your vehicle. Attempting to use any device during the test will result in when ready disqualification and may affect your ability to retake the test.
What is the difference between the written test for a regular driver license and a commercial driver license?
The written test for a commercial driver license (CDL) is much longer and more difficult. It covers additional topics like air brakes, hazardous materials, and large vehicle handling. If you are seeking a regular driver license, you only take the standard 36-question test. A CDL requires a separate, more extensive written test and additional behind-the-wheel testing.
If I pass the written test but fail the driving test, do I have to retake the written test?
Not when ready. Your passing written test score is valid for 12 months. You can retake the driving test as many times as you need within that year without retaking the written test. However, if 12 months pass without passing the driving test, you will need to retake the written test before you can continue.
Are there any topics on the California written test that are not in the Driver Handbook?
No. Every question on the written test is based on material in the California Driver Handbook. If you read the handbook thoroughly and take the sample test included in it, you will have seen the types of questions and topics that appear on the real test.
What if I need to take the test in a language other than English or Spanish?
Contact your local DMV office at least two weeks before your planned test date to confirm that your language is available. If it is not available at your local office, the DMV can often arrange for you to test at a different location or provide a certified interpreter. Some languages may require additional notice or travel to a regional DMV office.
