What the California DMV Permit Test Covers
California's written permit test, officially called the knowledge test, is a 46-question multiple-choice exam that covers traffic laws, road signs, and safe driving practices specific to California. You must answer at least 39 questions correctly to pass. The test is offered in multiple languages including English, Spanish, Mandarin, Vietnamese, and others — you choose your language when you schedule your appointment or arrive at the DMV office.
The test draws from the California Driver Handbook, a free publication you can read online or pick up at any DMV office. Every question on the exam comes directly from material in that handbook. The test focuses on what you need to know to drive safely and legally in California: speed limits, right-of-way rules, parking laws, what different road signs mean, how to handle emergencies, and the rules for sharing the road with pedestrians and cyclists.
You take the test on a computer at a DMV office or, in some cases, through an approved third-party tester. The exam is untimed, though most people finish in 10 to 20 minutes. You receive your score when ready after you submit your answers.
Key Takeaways
- The California knowledge test has 46 questions, and you need 39 correct answers to pass — that is about 85 percent.
- All test content comes from the California Driver Handbook, which you can read for free online or at any DMV office before you test.
- You can take the test in 32 languages, and you choose your language when you book your appointment or arrive at the office.
- You must be at least 15 years and 6 months old to take the test, and you need a valid ID and proof of residency to sit for the exam.
- If you fail, you can retake the test the same day at most DMV offices, though you may have to wait and pay the test fee again.
Documents You Need to Bring
Bring a valid form of identification and proof of California residency. A valid ID can be a passport, a state ID from another state, a military ID, or a tribal ID. If you do not have one of those, bring two documents that together show your identity and date of birth — for example, a school ID plus a birth certificate, or a work ID plus a Social Security card.
For proof of residency, bring one document dated within the last 60 days that shows your name and a California address. A utility bill, lease agreement, mortgage statement, or bank statement all work. A government check or tax return also counts. If you live with someone else and do not have a document in your name, bring a signed letter from the person whose name is on the document, plus your ID, plus a second document showing your relationship — such as a school enrollment letter or a lease with both names.
You do not need to bring the Driver Handbook to the test, and you cannot use it during the exam. You also cannot bring a phone, calculator, or any other device into the testing area.
How to Schedule Your Test Appointment
Book your appointment online through the California DMV website or by calling 1-800-777-0133. Online scheduling is faster and lets you pick your preferred date, time, and location. You can also walk into a DMV office without an appointment, but wait times are often longer, especially in urban areas.
When you schedule online, you will need to provide your name, date of birth, and the type of ID you plan to bring. You will also choose your test language and whether you need any testing accommodations — for example, extra time if you have a documented disability, or a reader if you have a vision impairment. The DMV office will confirm your appointment and send you a confirmation number.
Arrive at least 10 minutes early on the day of your test. Bring all required documents and your confirmation number. If you are under 18, you do not need a parent or guardian present for the written test, though you will need one when you take your behind-the-wheel driving test later.
What Happens If You Fail the Test
If you do not pass, you can retake the test when ready at most DMV offices — you do not have to wait days or weeks. You will pay the test fee again, which varies by location but is typically $5 to $10. Some offices let you retake the test the same day; others require you to schedule a new appointment, which might be the next day or later depending on availability.
You can retake the test as many times as you need. There is no limit on the number of attempts. However, each attempt costs the test fee, and you must wait between attempts if the office does not offer same-day retesting. Most people pass on the second or third try if they study the handbook more carefully after their first failure.
If you fail three times, some DMV offices may require you to wait a certain period before your next attempt — check with your local office for their specific policy. The best approach after a failure is to go home, review the sections of the Driver Handbook you found confusing, and come back when you feel ready.
Study Materials and Test Preparation
The California Driver Handbook is your primary study resource. It is available free online at the DMV website, and you can read it as a PDF or read it in your browser. You can also pick up a printed copy at any DMV office. The handbook is organized by topic — traffic laws, road signs, parking, pedestrians, and so on — which makes it straightforward to focus on areas where you feel weak.
The DMV also offers a free practice test on its website. This practice test has the same format and difficulty as the real exam and covers the same material. Taking the practice test multiple times is one of the most effective ways to prepare. Many people take it until they consistently score above 90 percent, then feel confident taking the real test.
Some third-party websites and apps offer practice tests as well. These can be helpful, but make sure they are based on the current California Driver Handbook. The DMV's official practice test is always accurate and free, so start there.
Age Requirements and Permit Validity
You must be at least 15 years and 6 months old to take the knowledge test in California. Once you pass, you receive a learner's permit (also called a provisional license or instruction permit) that is valid for 12 months. During that year, you can practice driving with a licensed adult who is at least 25 years old and sitting next to you in the front seat.
If your permit expires before you pass your behind-the-wheel driving test, you will need to retake the knowledge test. The test fee applies again. For this reason, many people schedule their driving test within a few months of passing the written test, rather than waiting until near the end of the 12-month window.
If you are under 18, California has additional rules: you must hold your permit for at least 6 months before you can take the driving test, and you must complete a driver education course and a behind-the-wheel training course. Adults 18 and older do not have these waiting periods or course requirements.
Testing Accommodations and Language Options
If you have a disability or medical condition that affects your ability to take the test, you can request accommodations. Common accommodations include extra time (usually 1.5 times the standard time), a reader who reads questions aloud, a magnifier for people with low vision, or a separate testing room with fewer distractions. Request accommodations when you schedule your appointment or contact your local DMV office at least two weeks before your test date.
The DMV offers the test in 32 languages. When you schedule your appointment online or call to book, you will select your language. If your preferred language is not available at your local office, the DMV can sometimes arrange testing at a different location or on a different date. Do not assume your language is unavailable — ask the DMV directly.
Frequently Asked Questions
Can I use the California Driver Handbook during the test?
No. The test is closed-book. You cannot bring the handbook, your phone, notes, or any reference material into the testing area. You must study the handbook before you arrive at the DMV office.
What if I fail the test twice — do I have to wait before trying again?
Most DMV offices let you retake the test when ready, even on the same day. However, a few offices require you to schedule a new appointment, which might be the next day or later. Call your local DMV office to ask about their retesting policy.
Is the practice test on the DMV website the same difficulty as the real test?
Yes. The official DMV practice test uses the same question bank and format as the real exam. If you consistently score 90 percent or higher on the practice test, you are very likely to pass the real test.
Do I need to take a driver education course before I can take the knowledge test?
No, not for the written test. However, if you are under 18, you must complete a driver education course before you can take your behind-the-wheel driving test. Adults 18 and older do not have this requirement.
What happens if my learner's permit expires before I take my driving test?
Your permit is valid for 12 months. If it expires, you must retake the knowledge test and pay the test fee again. Schedule your driving test well before your permit expires to avoid this.
