California's Written Test Has Two Routes and Different Rules for Each
California offers two written tests: the knowledge test for a learner's permit, and the written portion of the driving test for a full license. They are not the same exam, they test different material, and you cannot use one to skip the other. The knowledge test covers traffic laws and road signs. The written portion of the driving test covers vehicle operation and safety decisions. Both are multiple-choice, both are administered at a DMV office, and both must be passed before you can take the behind-the-wheel test.
You take the knowledge test first, usually weeks or months before the driving test. You must pass it to get your learner's permit. The written portion of the driving test comes later, on the same day as your behind-the-wheel test, and you must pass both to receive your license. If you fail either written test, you can retake it, but there are waiting periods and limits on how many times you can test in a given period.
Key Takeaways
- The knowledge test for a learner's permit covers California traffic laws, road signs, and safe driving rules, and you must pass it before scheduling a behind-the-wheel test.
- The written portion of the driving test is a separate exam taken on the same day as your behind-the-wheel test and covers vehicle operation and real-world driving decisions.
- Both tests are multiple-choice, administered on a computer at a DMV office, and you must score at least 83 percent to pass.
- If you fail a written test, you must wait at least one day before retaking it, and you can take it no more than three times in a 12-month period without a waiting period.
- The DMV provides a free study guide for each test, available online and in print at any DMV office.
The Knowledge Test: What It Covers and How to Prepare
The knowledge test has 36 multiple-choice questions and covers California Vehicle Code, traffic signs, and safe driving practices. You have 10 minutes to complete it. The test is administered on a computer at any DMV office, and you can take it in English or one of several other languages. You must score at least 30 out of 36 questions correct (83 percent) to pass.
The DMV publishes the California Driver Handbook free online and in print. This handbook contains all the material covered on the knowledge test. You can read it as a PDF from the DMV website or pick up a printed copy at any DMV office. Many people study the handbook for a few weeks before testing. The handbook covers right-of-way rules, speed limits, parking, stopping distances, alcohol and drug laws, and what different road signs mean.
You do not need to take a driver education course to take the knowledge test, though some people do. If you are under 18, California requires you to complete a driver education course before you can take the behind-the-wheel test, but not before the knowledge test. If you are 18 or older, no course is required for either test.
The Written Portion of the Driving Test: Content and Timing
The written portion of the driving test is shorter than the knowledge test. It has 6 multiple-choice questions and you have 10 minutes to complete it. You must score at least 5 out of 6 correct (83 percent) to pass. This test is taken on the same day as your behind-the-wheel test, before you drive with the examiner.
The written portion tests your ability to make safe decisions behind the wheel. Questions ask what you would do in specific driving situations — for example, how to handle a four-way stop, what to do if your brakes fail, or how to respond to a traffic signal that is not working. The DMV study guide for the driving test covers these scenarios. You can read it from the DMV website or request a printed copy at a DMV office.
If you fail the written portion on the day of your driving test, you do not take the behind-the-wheel test that day. You must retake the written test before scheduling another full driving test appointment. This can add weeks to the process, so many people study both the knowledge test handbook and the driving test guide before their appointment.
Retaking a Failed Test and Waiting Periods
If you fail either written test, you can retake it. You must wait at least one day before retaking the same test. You can take the knowledge test or the written portion of the driving test up to three times in a 12-month period without a waiting period beyond that one day. After three attempts in 12 months, you must wait one month before taking it again.
The 12-month period runs from the date of your first attempt, not from the calendar year. If you fail on January 15, your 12-month window closes on January 14 of the following year. After you pass a test, the counter resets if you later need to retake it.
Keep in mind that if you fail the written portion of the driving test, you also lose your behind-the-wheel test appointment for that day. You will need to schedule a new appointment after you pass the written test. DMV appointments can be weeks out, so plan accordingly.
Test Format, Languages, and Accessibility
Both written tests are administered on a computer at a DMV office. You sit at a terminal, read each question on the screen, and select your answer using the keyboard or mouse. The test is timed, but most people finish well before the time limit. You receive your score when ready after completing the test.
The tests are available in English and in Spanish, Cantonese, Mandarin, Vietnamese, Korean, Tagalog, Russian, Arabic, and Hmong. You select your language when you schedule your test appointment or when you arrive at the DMV office. If you need the test in a language not listed, contact your local DMV office to ask about other options.
If you have a disability or need accommodations, the DMV can provide extra time, a reader, a writer, or a large-print version of the test. You must request accommodations when you schedule your appointment. Contact your local DMV office at least two weeks before your test date to arrange this.
How to Schedule Your Test and What to Bring
You schedule the knowledge test online through the DMV website or by calling your local DMV office. You can also walk in to some DMV locations and take the test the same day, though wait times vary. To schedule online, you will need to create a DMV account and provide your name, date of birth, and driver's license number or identification number.
When you arrive for your test, bring a valid form of identification. Acceptable forms include a passport, a state ID card, a school ID with your photo, or a work ID. You do not need to bring the study guide or any notes. In fact, you cannot bring study materials into the testing area.
The written portion of the driving test is scheduled as part of your behind-the-wheel test appointment. You book the driving test appointment online or by phone, and the written test is automatically included. You take the written test first, and if you pass, you proceed to the behind-the-wheel test with the same examiner.
Common Mistakes and How to Avoid Them
Many people fail the knowledge test because they do not study the handbook thoroughly. The test includes questions about specific laws — for example, the exact speed limit in a school zone or the distance you must stay behind a fire truck. These details are in the handbook, and they appear on the test. Skimming the handbook is not enough; you need to read it carefully and review sections more than once.
Another common mistake is confusing the knowledge test with the written portion of the driving test. They are different exams with different material. Studying for one does not prepare you for the other. Make sure you know which test you are taking and study the correct guide.
On test day, read each question carefully before answering. Multiple-choice questions can have similar-sounding answers, and rushing through them leads to mistakes. You have 10 minutes for either test, which is plenty of time to read carefully and think about your answer.
Frequently Asked Questions
Can I take the knowledge test online from home?
No. Both the knowledge test and the written portion of the driving test must be taken at a DMV office on a computer provided by the DMV. You cannot take either test remotely or on your own device.
What happens if I fail the written portion of the driving test?
You do not take the behind-the-wheel test that day. You must retake the written test and pass it before scheduling another full driving test appointment. You can retake the written test one day later, but you will need to schedule a new behind-the-wheel appointment, which may be weeks away.
Do I need to take a driver education course before the knowledge test?
No, not for the knowledge test. If you are under 18, you must complete a driver education course before the behind-the-wheel test, but not before the knowledge test. If you are 18 or older, no course is required for either test.
How long is the knowledge test?
The knowledge test has 36 questions and you have 10 minutes to complete it. Most people finish in 5 to 8 minutes. The written portion of the driving test has 6 questions and also allows 10 minutes.
Can I use the study guide during the test?
No. You cannot bring any study materials, notes, or reference books into the testing area. You must answer all questions from memory based on your preparation.
