How California's Written Test Works

California's written knowledge test is a computer-based exam you take at a DMV office. You answer 36 multiple-choice questions about traffic laws, road signs, and safe driving practices. You need to answer at least 30 questions correctly — that is a score of 83 percent — to pass.

The test is given in English and in 32 other languages, including Spanish, Mandarin, Vietnamese, Korean, Tagalog, and Arabic. You choose your language when you schedule your appointment or arrive at the DMV office. If English is not your first language, you can request an interpreter, though you must arrange this in advance by calling your local DMV office.

The test covers only California traffic laws and road signs. You cannot bring study materials, phones, or notes into the testing room. The DMV provides scratch paper and a pencil. You have no time limit, though most people finish in 10 to 20 minutes.

Key Takeaways

  • You must score at least 30 out of 36 questions correct (83 percent) to pass California's written test.
  • The test is computer-based and available in 33 languages at DMV offices throughout the state.
  • You study from the California Driver Handbook, which the DMV publishes free online and in print at every DMV office.
  • If you fail, you can retake the test the same day at most DMV locations, though you may have to wait and pay the test fee again.
  • You must pass the written test before you can schedule a behind-the-wheel driving test.

What the Test Covers

The 36 questions come from six main topics: right-of-way rules, safe driving practices, traffic signs and signals, parking and stopping, vehicle equipment, and California-specific laws. Questions are drawn from the California Driver Handbook, which is the official study material. Every question on the test appears in that handbook or is directly based on information in it.

Road sign questions make up a significant portion of the test. You will see images of actual California traffic signs and must identify what they mean or what action they require. These include warning signs (yellow diamonds), regulatory signs (white rectangles), and information signs (green rectangles).

Right-of-way questions test your understanding of who has the legal right to go first in specific situations: at four-way stops, when turning left, when merging, and when pedestrians are present. Safe driving questions cover topics like following distance, speed limits, distracted driving, and what to do in emergencies.

How to Study for the Test

The California Driver Handbook is your primary study resource. You can read it free as a PDF from the DMV website (dmv.ca.gov), or pick up a printed copy at any DMV office. The handbook is organized by topic and includes sample test questions at the end of each section.

The DMV also offers a free online practice test on its website. This practice test has 36 questions in the same format as the real test and covers the same topics. Taking the practice test multiple times helps you identify which topics you need to study more. Many people take the practice test three or four times before taking the real test.

Some people use third-party study apps or websites, but these are not official DMV materials. Stick to the Driver Handbook and the official DMV practice test to may support you are studying exactly what will appear on the real exam.

When You Can Take the Test

You can take the written test only after you have a valid instruction permit (learner's permit). You must hold the permit for at least six months before you can take the behind-the-wheel driving test, but you can take the written test as soon as you receive the permit.

You schedule the written test through the DMV website or by calling your local DMV office. Most offices offer appointments within one to two weeks, though wait times vary by location. Some offices also accept walk-ins for the written test, but appointment availability is more reliable.

The test is offered during regular DMV office hours, which are typically Monday through Friday, 8 a.m. to 5 p.m., with some offices open on Saturday mornings. You must bring your instruction permit and a valid form of identification (such as a passport or state ID) to take the test.

What Happens If You Fail

If you score below 30 out of 36, you fail the test. You can retake it the same day at most DMV locations, though you may have to wait for the next available testing slot and pay the test fee again. The test fee in California is $13 as of 2024, though this may change.

There is no limit to how many times you can retake the test. Some people pass on the first try; others take it two or three times. Each time you retake it, you get a new set of 36 questions drawn from the same pool of topics.

If you fail multiple times, go back to the Driver Handbook and the practice test. Focus on the topics where you are missing questions. Many people find that taking the practice test several more times and reviewing specific sections of the handbook helps them pass on the next attempt.

Documents You Need to Bring

Bring your California instruction permit and a valid form of identification. Valid forms of ID include a U.S. passport, a passport card, a consular ID card, a military ID, a tribal ID, or a permanent resident card. If you do not yet have an instruction permit, you cannot take the written test.

You do not need to bring the Driver Handbook or any study materials. You do not need to bring proof of residency, proof of Social Security number, or any other documents. The DMV provides scratch paper and a pencil for your use during the test.

If you are taking the test in a language other than English and have arranged for an interpreter, bring the interpreter with you or confirm that the DMV office has arranged one on your behalf.

After You Pass the Written Test

Once you pass the written test, you receive a passing score notice. You can then schedule your behind-the-wheel driving test. You must hold your instruction permit for at least six months before you can take the driving test, so if you pass the written test before six months have passed, you will have to wait.

Your passing score is valid for one year. If you do not schedule and take the driving test within one year of passing the written test, you will have to take the written test again.

During the six-month waiting period, you can practice driving with a licensed adult who is at least 25 years old and sitting in the front passenger seat next to you. This practice time is important — it helps you build the skills you will need to pass the driving test.

Frequently Asked Questions

Can I take the written test before I get my instruction permit?

No. You must have a valid California instruction permit before you can take the written test. You get the instruction permit by passing a vision test and paying a fee at the DMV. Once you have the permit, you can take the written test.

What if I fail the written test three times?

There is no limit to how many times you can retake the test. If you fail three times, you can retake it a fourth time. Each time, you pay the test fee again. Focus your study on the topics where you are missing the most questions.

Is the written test the same in every California DMV office?

Yes. The test is the same statewide — same 36 questions drawn from the same pool, same passing score of 30 out of 36. The only difference is the language you choose and whether you use an interpreter.

How long is my passing score valid?

Your passing score is valid for one year from the date you pass. You must schedule and take the behind-the-wheel driving test within that year. If you do not, you will have to retake the written test.

Can I use a calculator or notes during the test?

No. You cannot bring any materials into the testing room except your permit and ID. The DMV provides scratch paper and a pencil if you need to write anything down during the test.
