What the California written permit test covers

California's written permit test, officially called the knowledge test, is a 46-question multiple-choice exam you take at the Department of Motor Vehicles (DMV) to get your learner's permit. You need to answer at least 39 questions correctly to pass. The test covers California traffic laws, road signs, safe driving practices, and what to do in emergency situations.

The test is based entirely on the California Driver Handbook, a free booklet the DMV publishes and updates yearly. Every question on the exam comes from material in that handbook — nothing is a trick question or based on information outside it. You can take the test in English or in one of several other languages, and you can request a reader or other accommodations if you need them.

You must be at least 15 years and 6 months old to take the test and get a learner's permit. Once you pass, you can drive with a licensed adult who is at least 25 years old and sitting next to you in the front seat. The permit is valid for 12 months.

Key Takeaways

  • The test has 46 multiple-choice questions, and you need 39 correct answers to pass — that is about 85 percent.
  • Every question comes from the California Driver Handbook, which you can read free online or pick up at any DMV office.
  • You must schedule your test appointment at the DMV in advance; walk-ins are not accepted for the written test.
  • Bring your completed DL 44 form, proof of California residency, proof of your Social Security number, and proof of your date of birth to the test.
  • You can retake the test if you fail, but you must wait at least one day before scheduling another appointment.

What documents you need to bring to the DMV

Before you go to the DMV for your test, gather these documents. You will need your completed DL 44 form (the process for a driver's license or permit), which you can fill out at home or at the DMV. You also need proof of your California residency — a utility bill, lease agreement, or bank statement with your name and current address works.

Bring proof of your Social Security number, such as your Social Security card itself or a tax return with your full number on it. You will also need proof of your date of birth — a birth certificate, passport, or school record. If you are under 18, bring a parent or guardian with you; they will need to sign your DL 44 form in front of the DMV employee.

The DMV website lists the full set of acceptable documents for each category. If you are unsure whether a document will work, call your local DMV office before your appointment or check the DMV's document requirements page online.

How to schedule your test appointment

You cannot walk into a DMV office and take the written test the same day. You must book an appointment in advance through the DMV website or by calling 1-800-777-0133. When you schedule online, you will choose your nearest DMV office, pick a date and time that works for you, and confirm your appointment.

The DMV typically has appointment slots available several weeks out, though availability varies by location and season. If your local office is fully booked, you can try scheduling at a different DMV office nearby. Write down your appointment confirmation number and the date and time — you will need this information when you arrive.

If you need to reschedule or cancel, do so through the same website or phone number at least 24 hours before your appointment. If you miss your appointment without canceling, you may have to wait longer to get another slot.

How to study the California Driver Handbook

The California Driver Handbook is the only official source for test content. You can read it free as a PDF from the DMV website, read it online, or pick up a printed copy at any DMV office. The handbook is organized by topic: traffic laws, road signs, right-of-way rules, parking, speed limits, driving under the influence, and more.

Read through the entire handbook at least once, paying close attention to sections that cover rules you use every day — stop signs, traffic lights, lane changes, and turning. Many test questions focus on what to do at intersections and how to handle pedestrians and cyclists. Spend extra time on the road signs section, because the test includes questions that show you a sign and ask what it means.

Take notes as you read, or highlight key points. Some people find it helpful to read a section, close the handbook, and try to write down what they remember. Others reread sections multiple times. The method that works best depends on how you learn, but the goal is to move the information from short-term memory into long-term memory so you can recall it under test pressure.

Practice tests and what to expect on test day

Many free practice tests are available online through the DMV website and other sites. These practice tests use the same format and question types as the real test, so taking them helps you get used to how questions are worded and what kinds of answers the DMV is looking for. Practice tests also show you which topics you understand well and which ones need more study.

On test day, arrive at your DMV appointment 10 to 15 minutes early. Bring all your documents and your confirmation number. The DMV employee will check your documents, verify your identity, and take your photo for your permit. You will then sit at a computer or paper test station and answer the 46 questions. You have no time limit, though most people finish in 20 to 30 minutes.

You will see your score when ready after you finish. If you pass, you will get your learner's permit on the spot. If you do not pass, you can schedule another test appointment. You must wait at least one day before retaking the test, and you can retake it as many times as you need to.

What happens after you pass the written test

Once you pass the written test, you receive your learner's permit, which is valid for 12 months. With your permit, you can drive on public roads only when a licensed adult who is at least 25 years old is sitting in the front passenger seat next to you. That adult must hold a valid driver's license.

During the 12 months you have your permit, you are building supervised driving experience. California law requires you to hold your permit for at least six months before you can take the driving test (the behind-the-wheel exam). If you are under 18, you must also complete a driver education course and a behind-the-wheel training course before you take the driving test.

Keep your permit with you whenever you drive. If you lose it, you can get a replacement at the DMV. When you are ready to take the driving test, you will schedule another DMV appointment, bring your permit and documents, and take the test with a DMV examiner in your car.

Common mistakes to avoid when studying

Many people study only the road signs section and skip the rest of the handbook. Road signs are important, but the test also covers parking rules, speed limits, right-of-way situations, and what to do in bad weather or emergencies. Spread your study time across all topics in the handbook.

Another common mistake is memorizing answers to practice test questions without understanding the rule behind them. If you see a question about stopping distance and you memorize "100 feet," you might get confused if the real test asks the same question in different words. Instead, understand why the stopping distance matters and how it changes based on speed and road conditions.

Do not cram the night before the test. Your brain needs time to move information into long-term memory, and cramming leaves you tired and stressed on test day. Start studying at least one week before your appointment, and review the handbook a little bit each day rather than all at once.

Frequently Asked Questions

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

Yes. The DMV offers the written test in English, Spanish, Chinese, Hindi, Japanese, Korean, Tagalog, Thai, and Vietnamese. When you schedule your appointment online or by phone, you can select your preferred language. If your language is not listed, contact your local DMV office to ask about other options.

What if I fail the test?

You can retake the test as many times as you need. You must wait at least one day before scheduling another appointment. Review the handbook again, focusing on the topics you found hardest, and take more practice tests before your next attempt. Most people pass on their second or third try.

Do I need to take a driver education course before the written test?

No. You can take the written test without completing driver education. However, if you are under 18, you must complete a driver education course and a behind-the-wheel training course before you can take the driving test. If you are 18 or older, driver education is not required, though it is still recommended.

How long is my learner's permit valid?

Your learner's permit is valid for 12 months from the date you receive it. If it expires before you take the driving test, you will need to retake the written test to get a new permit. You can renew your permit at the DMV if you need more time.

Can I use my phone or notes during the test?

No. The test is proctored, meaning a DMV employee watches while you take it. You cannot use your phone, notes, the handbook, or any other materials during the test. You must answer all questions from memory based on what you studied.
