The California knowledge (permit) test
The knowledge test is the written exam you pass to get a California instruction permit. It checks that you understand traffic laws, signs and safe driving before you ever get behind the wheel.
It is based entirely on the California Driver's Handbook, so the handbook is your main study guide.
By the end of this topic you can
- You can describe the format of the knowledge test and its pass mark.
- You can explain how many attempts you get and how long minors wait after a fail.
- You can list the handbook topics the test draws from.
- You can plan a study routine using official DMV materials.
What you need to know and understand
- The test is multiple choice and based on the California Driver's Handbook.
- The DMV sets the passing score at 80 percent.
- You get three attempts on one application before you must reapply and pay again.
- Minors must wait seven days after a failed test, not counting the day of the fail.
- Testing aids are banned, including the handbook and cell phones.
- DMV offices do not give knowledge tests after 4:30 p.m.
- New residents with a valid out-of-state license must pass a knowledge test, but the DMV does not list a drive test for them.
What the test looks like
You answer multiple-choice questions, usually on a touchscreen at the DMV office, and your score is marked automatically. The DMV states the passing score as 80 percent. The number of questions can vary by test type, so check your appointment details or our deeper California knowledge test guide rather than relying on a figure you heard from a friend.
Questions come from across the handbook. Expect plenty on traffic signs and signals, right of way, speed limits, lane use, parking and curb colors, sharing the road, alcohol and drug laws, and what to do after a collision.
If you do not pass
- You can retake the test, up to three attempts on one application.
- If you are under 18, wait seven days before the next try. The day you failed does not count.
- After three fails, the application is no longer valid. You must reapply and pay the fee again.
- Your application and fee are valid for 12 months, so plan your attempts inside that window.
A study plan that works
- Read the handbook section by section, a little each day, rather than cramming the night before.
- Make your own flashcards for numbers: speed limits, parking distances and blood alcohol limits.
- Take the free DMV sample tests and our California permit practice test until you score well above 80 percent.
- Go back to the handbook for every question you miss and find the rule behind it.
- Book a morning appointment so you are fresh and well before the 4:30 p.m. cutoff.
Common mistakes
- Studying only practice questions and never reading the handbook. The real questions are worded differently.
- Bringing your phone or notes into the test. Testing aids are banned.
- Rushing questions with numbers. Read every option, because wrong answers are often close figures.
- Booking late in the afternoon and running out of time before the cutoff.
