To pass the California permit test, you need to score at least 80%. If you’re under 18, you take a 46-question version and can miss up to 9 questions. If you’re 18 or older, you take a 36-question version and can miss up to 7. The threshold is the same for both groups; only the question count differs.1State of California Department of Motor Vehicles. Instruction and Learner’s Permits
The Miss Counts by Age
- Under 18 (46 questions): at least 37 correct to pass. Up to 9 wrong is still a pass.
- 18 and older (36 questions): at least 29 correct to pass. Up to 7 wrong is still a pass.
The longer version for minors exists because they’re also tested on topics tied to provisional licensing. The passing percentage doesn’t budge either way.1State of California Department of Motor Vehicles. Instruction and Learner’s Permits
The margin sounds more forgiving than it is. Seven wrong on the adult test works out to roughly one miss per five questions, and a few careless answers on topics you skimmed can close the gap fast.
What the Test Looks Like
The knowledge test is multiple choice. Each question offers three answer choices, one correct and two incorrect, and every question comes directly from the California Driver Handbook.2State of California Department of Motor Vehicles. Knowledge and Drive Tests Preparation About a quarter of the questions cover road signs and pavement markings, and the rest cover general rules of the road.
You take the test at a DMV office, either on paper or on a computer terminal. It’s offered in English, Spanish, Armenian, Chinese, Hindi, Punjabi, and Vietnamese. The DMV’s online eLearning option is not available for first-time permit seekers; it exists for eligible renewal applicants.3State of California Department of Motor Vehicles. Online Learning
Topics That Trip People Up
Road sign recognition tends to be the easier half of the test. The questions that quietly eat into your allowed misses are usually about specific rules and numbers:
- Right-of-way rules: especially at uncontrolled intersections and when merging onto freeways.
- BAC limits: California sets different blood alcohol thresholds depending on age and license type.
- Following distances and posted speeds: the handbook lists specific figures for school zones, residential areas, and other contexts, and the test asks about them directly.
If You Fail
You get three attempts to pass the knowledge test within your 12-month application period, and all three are covered by your initial application fee.4State of California Department of Motor Vehicles. California Driver’s Handbook – The Testing Process If you use up all three without passing, the application expires and you have to start over with a new application and a new fee.1State of California Department of Motor Vehicles.

Applicants under 18 must wait at least seven days before retaking a failed knowledge test. The day you failed does not count toward that waiting period.4State of California Department of Motor Vehicles. California Driver’s Handbook – The Testing Process Adults have no mandatory wait, though local scheduling can create a delay in practice.
How to Prepare
Every question is drawn from the California Driver Handbook, so reading it through is the single most effective thing you can do.2State of California Department of Motor Vehicles. Knowledge and Drive Tests Preparation The handbook is available as a free PDF on the DMV website. Give yourself several days rather than cramming; a lot of the test hangs on details that are easy to skim past.
Practice tests are the next best tool. The DMV posts sample questions online, and many free third-party practice exams follow the actual format. Their real value isn’t memorizing answers. It’s spotting which handbook sections you absorbed and which you didn’t. If you keep missing questions on lane markings or sharing the road with bicycles, go back and reread those specific sections instead of retaking the same practice test.
