The California Driver's Handbook, and what the test takes from it
DL 600 is the document the DMV writes the knowledge test from. It is free, it is long, and not all of it is examinable in the same measure. Here is how it breaks down, and where the 1,980 questions in our bank sit against it.
The topics, and how much of the bank each one carries
- 1 Introduction 99
- 2 Requirements and Process 135
- 3 Rules of the Road: Traffic Laws in California 179
- 4 Defensive Driving and Safe Driving Practices 179
- 6 Alcohol, Drugs, and Driving (DUI Laws) 107
- 7 Insurance and Financial Responsibility 105
- 8 Emergencies and Unforeseen Situations 105
- 5 Traffic Signs, Signals and Road Markings — all 1044 signs 1044
There is not one knowledge test, there are three
| Who sits it | Questions | Errors allowed |
|---|---|---|
| Adult, first license | 36 | 6 |
| Renewal | 18 | 3 |
| Under 18 (provisional) | 46 | 8 |
All three land on roughly the same 83% standard. Most practice sites quote only the 36-question form, which is the one an adult getting a first California license actually sits.
Three things the handbook says that people get wrong
The seven-day wait is for minors
The handbook says minors must wait seven days to retake a failed knowledge test, not counting the day of the failure. Plenty of sites repeat that rule as if it applied to everyone.
You get three attempts, then you reapply
Not three per visit and not unlimited: three attempts to pass before you must reapply.
No aids of any kind during the test
Explicitly including a copy of the handbook itself and your phone.

The three test forms come from the DMV's own Evaluation of the Class C Driver License Written Knowledge Tests, published on dmv.ca.gov — an official document, though its figures date from 2006. The handbook is published free by the DMV: read it at dmv.ca.gov.
