California DMV Written Test: Practice & Study Guide
What to expect on the California DMV written knowledge test, how many questions you can miss, study tips, and where to find free official practice tests.
The California DMV written knowledge test trips up more first-timers than people expect. The good news: it is very beatable with a little focused study, and California offers free official practice tests. Here is exactly what to expect and how to prepare.
Quick answer: The standard test for a Class C license has 36 questions, and you must answer at least 30 correctly (about 83%) to pass. You get three attempts per application. Study the official California Driver Handbook and take the free practice tests on dmv.ca.gov before test day.
What the test covers
Questions are drawn from the California Driver Handbook and cover road rules, traffic signs, safe driving practices, right-of-way, speed limits, and penalties for impaired driving. Most are multiple choice with one correct answer. Signs and right-of-way questions are the most commonly missed, so give those sections extra attention.
How many questions and the passing score
For an original Class C (regular) license, the test has 36 questions and you may miss no more than 6 — you need 30 correct to pass. Drivers under 18 take a longer 46-question version and must answer at least 38 correctly. If you do not pass, you can retake it, up to three attempts per application.
Free official practice tests
The California DMV publishes free interactive practice tests and sample questions on its website. These mirror the style and difficulty of the real exam and are the single best way to prepare. Find them on the official dmv.ca.gov sample test pages. Work through the practice tests until you are consistently scoring above 90% before booking your appointment.
Study tips that actually work
Read the current California Driver Handbook cover to cover at least once — every test question comes from it. Focus your repetition on traffic signs (memorize shapes and colors), right-of-way rules at intersections, and following-distance and speed rules. Take a practice test, review every question you missed, and retake until the misses disappear.
Test day: what to bring
You take the knowledge test at a DMV field office, so bring your identity and residency documents, your application confirmation, and payment for the application fee. The test is typically taken on a touchscreen terminal at the office. Bring your reading glasses if you use them — there is also a vision screening.
