Short answer: Study the California Driver’s Handbook, because the DMV says every test question comes from it. Make a list of the numbers and rules that are easy to mix up, then take practice tests until you are scoring well above the 80% you need to pass. Plan on one to two weeks of short daily sessions, and go over the tips below before test day.

The California permit test is called the knowledge test. Here is what the DMV says about it:
- It is multiple choice. Each question has one correct answer and two choices that are wrong or don’t fit.
- All questions come from the California Driver’s Handbook.
- You need 80% to pass.
- There are no trick questions, according to the DMV.
- You get three attempts before you must reapply. If you are under 18, you must wait seven days to retake a failed test.
- You can’t use the handbook, a cell phone or any other testing aid during the test.
The DMV doesn’t publish how many questions are on the test. Our guide on how many questions are on the permit test explains what that means for how many you can miss.
A study plan that fits in two weeks
Thirty to sixty minutes a day is plenty. Short, regular sessions help you remember more than one long night of cramming.
- Get the official handbook. It is free on dmv.ca.gov, online or as a PDF in English, Spanish and other languages. Don’t pay for a copy.
- Take a practice test first. Before you read anything, take the free 10-question practice test or a DMV sample test. Your misses show you where to focus.
- Read the handbook in chunks (days 1 to 7). Spend the most time on Sections 5 through 9: driving basics, navigating the roads, laws and rules of the road, safe driving, and alcohol and drugs. Our handbook study guide has a day-by-day reading plan.
- Build a numbers sheet. Each time you see a distance, speed, age or time, write it down. See the table below for a head start.
- Learn signs by shape and color. Signs and signals are in Section 7. Our road signs guide puts them in one place.
- Practice test, then review (days 8 to 12). Take a practice test every day. For each wrong answer, find the rule in the handbook and reread the whole paragraph, not just the answer.
- Use the DMV’s own samples. The DMV offers free sample knowledge tests, including four regular (Class C) tests in English and in Spanish.
- Do a final check (days 13 and 14). Reread your numbers sheet and any section you keep missing. Aim to score well above 80% several times in a row before you test.
Numbers worth memorizing
Questions with numbers are where many people slip, because the choices look close. Every number below comes from the handbook.
| Rule | Number |
|---|---|
| Signal before turning | At least 100 feet |
| Signal before changing lanes on a freeway | At least 5 seconds |
| Following distance | 3 seconds |
| Scan ahead | At least 10 seconds |
| Dim high beams for oncoming traffic | Within 500 feet |
| Dim high beams when following | Within 300 feet |
| Speed limit near a school when children are outside or crossing | 25 mph within 500 feet |
| Blind intersection or alley | 15 mph |
| Business or residential district (unless posted) | 25 mph |
| Stop for a train | At least 15 feet from the nearest track |
| No parking near a fire hydrant | Within 15 feet |
| Center left turn lane | Drive no more than 200 feet |
| Space when passing a bicyclist (if you can’t change lanes) | At least 3 feet |
| Blood alcohol limit, 21 and over / under 21 | 0.08% / 0.01% |
Also learn the curb colors: red means no stopping, standing or parking; white is for picking up or dropping off passengers; green is limited-time parking; yellow is for loading; blue is for disabled parking with a placard or special plate.
Extra topics for teens
If you are under 18, read Section 2 and the parts of Sections 7 through 9 written for young drivers. These rules apply to you directly:
- Practice at least 50 hours with a qualified driver, including 10 hours at night, and hold your permit at least six months (or until you turn 18) before the drive test.
- With a provisional license, you can’t drive between 11 p.m. and 5 a.m. during the first 12 months, and you can’t drive with passengers under 20 unless a parent, guardian or other qualified driver is with you. The handbook lists some exceptions.
- It is against the law for a minor to use a cell phone or wireless device to answer calls or send or respond to texts while driving. The exception is calling for emergency help.
- If you are under 21, you may not carry alcohol in a vehicle unless someone 21 or older is with you, and the container must be full, sealed and unopened.
Parents can help a lot here. Quiz your teen on these rules during practice drives. For the full picture, see our guides on learner’s permit rules and provisional license rules.
Test-day tips
- Arrive early. DMV offices don’t give knowledge tests after 4:30 p.m. You’ll also pay the fee, pass a vision exam and have your photo taken, so give yourself time. Check our list of what to bring to the DMV.
- Read every choice. The DMV says one answer is correct and the other two are wrong or don’t fit the question.
- Don’t overthink it. The DMV says there are no trick questions. Go with the answer the handbook gives, not what you have seen other drivers do.
- Stay calm. The DMV’s own advice is not to be nervous, because it wants you to pass.
- Thinking about testing at home? Some applicants can take the knowledge test online. See can you take the permit test online in California.
If you don’t pass the first time
It happens, and you still have more tries. If you miss a question at the office, the DMV says the employee can show you the handbook page with the correct answer. Write those topics down. If you are under 18, you’ll wait seven days before you can retake it, which is a good amount of time to reread the sections you missed. Then try the free practice test again before your next attempt.
