The California DMV permit test has 46 questions, and you must answer at least 39 correctly to pass

The written knowledge test for a California learner's permit (also called a permit test or written exam) contains exactly 46 multiple-choice questions. Each question has four possible answers. You need a score of 39 correct answers — which equals 85 percent — to pass and move forward to the driving test phase.

The test covers California traffic laws, road signs, safe driving practices, and vehicle operation. Every question comes from the California Driver Handbook, which is the official source document the DMV publishes. The handbook is available free online at the DMV website, and you can also request a printed copy at any DMV office.

You have one hour to complete the test. If you do not finish within that time, your test ends and you receive a failing score. Most people finish in 20 to 40 minutes, so time pressure is rarely the issue — understanding the material is.

Key Takeaways

  • The California permit test is 46 questions long, and you must answer at least 39 correctly to pass.
  • All questions come directly from the California Driver Handbook, so studying that handbook is the most direct way to prepare.
  • You have one hour to complete the test, though most test-takers finish in 20 to 40 minutes.
  • You can retake the test the same day if you fail, but you must wait at least one day between attempts.

What Topics the 46 Questions Cover

The DMV does not publish a breakdown of exactly how many questions cover each topic, but the test draws from these main areas: traffic signs and their meanings, right-of-way rules, speed limits and safe speeds, parking rules, vehicle equipment and maintenance, driving under the influence laws, seat belt and child safety seat requirements, and sharing the road with pedestrians, cyclists, and motorcycles.

Questions also cover California-specific rules that differ from other states, such as the state's mandatory seatbelt law, the hands-free cell phone requirement, and the rules for passing on two-lane highways. Some questions test your understanding of what to do in emergency situations — for example, what to do if your brakes fail or if you hydroplane on a wet road.

The test includes some questions about vehicle registration, insurance requirements, and what documents you must carry while driving. A smaller number of questions cover less common scenarios, such as how to handle a traffic control signal that is not working or how to proceed at a four-way stop.

How the Test Is Scored and What Happens If You Fail

The DMV scores your test when ready after you finish. A passing score is 39 or higher out of 46. If you score 38 or lower, you fail and do not receive your permit that day.

If you fail, you may retake the test the same day at most DMV offices, but you must wait at least one day before your second attempt. Some offices allow you to retake it when ready after a short break; others require you to schedule a new appointment. Call your local DMV office or check the DMV website to learn the policy at your location.

You can retake the test as many times as you need. There is no limit on the number of attempts, though each attempt requires paying the test fee again. In California, the permit test fee is currently $35, though this amount can change.

How to Prepare for All 46 Questions

The California Driver Handbook is the official study material. You can read it online at dmv.ca.gov or pick up a printed copy at any DMV office. The handbook is organized by topic and includes illustrations of road signs and diagrams showing right-of-way situations.

Many people study the handbook by reading it straight through, but a more effective approach is to focus on the areas where you feel weakest. If road signs confuse you, spend extra time on that section. If you are uncertain about right-of-way rules, drill those scenarios repeatedly.

The DMV also offers a practice test on its website. This practice test is not identical to the real test, but it uses the same question format and covers the same topics. Taking the practice test helps you understand what to expect and shows you which areas need more study. Some people take the practice test multiple times until they consistently score above 85 percent.

Test Format and Question Types

All 46 questions are multiple-choice with four answer options. You select your answer on a computer screen at the DMV office. There are no essay questions, no fill-in-the-blank questions, and no questions where you must identify a road sign by looking at an image alone — though some questions do include images of signs or road situations to help you understand the scenario.

Most questions ask you to choose the correct answer. Some questions ask you to identify the wrong answer or to select the best answer when more than one option might seem reasonable. Read each question carefully and consider all four options before choosing.

The test is offered in multiple languages, including Spanish, Chinese, Vietnamese, and others. If English is not your first language, you can request an interpreter at the DMV office when you schedule your test, though you must request this in advance.

When You Can Take the Test and What to Bring

You can take the permit test at any California DMV office during regular business hours. Most offices are open Monday through Friday, and some have limited Saturday hours. You must schedule an appointment in advance through the DMV website or by calling your local office. Walk-in testing is not available at most locations.

Bring your valid passport, birth certificate, or other proof of identity and legal presence in the United States. You will also need to bring proof of your Social Security number and proof of your California residence (such as a utility bill or lease). The DMV website lists the full set of acceptable documents.

Arrive at least 15 minutes early. You will complete a vision screening before the test begins. If you wear glasses or contacts, bring them with you. If you fail the vision screening, you will not be allowed to take the written test that day.

Frequently Asked Questions

Can I use the practice test to study instead of the handbook?

The practice test is a useful tool, but it should not be your only study method. The practice test shows you the format and some sample questions, but it does not cover every topic in the handbook. Reading the handbook gives you a complete picture of California traffic laws and helps you understand the reasoning behind the rules, not just memorize answers.

Do all 46 questions count toward my score?

Yes. Every question you answer counts. There are no "experimental" questions or questions that are scored differently. You need 39 correct answers out of 46 to pass.

What happens if I run out of time before answering all 46 questions?

If you do not submit your test within one hour, your test ends automatically and any unanswered questions are marked wrong. This is rare — most people finish in 20 to 40 minutes — but if you work slowly, pace yourself and move through questions steadily rather than spending five minutes on a single question.

Is the permit test harder than the driver's license test?

The permit test and the driver's license test are different. The permit test is a written knowledge test with 46 questions. The driver's license test includes a behind-the-wheel driving test where a DMV examiner observes your actual driving. The written portion of the driver's license test is shorter — 36 questions — but the driving portion is what most people find more challenging.

Can I bring study materials into the testing room?

No. You cannot bring the handbook, notes, a phone, or any other materials into the testing room. The test is proctored, and only you and your computer screen are allowed at your desk.
