Use this guide to understand how the California DMV Class C knowledge test is structured, what you should study, how passing works, and what happens if you do not pass on the first attempt.
QUICK ANSWER
California's Class C knowledge test uses multiple-choice questions based on the California Driver's Handbook. For instruction permits, DMV states that a passing score is 80%. Original driver-license applicants have three attempts to pass before they must reapply; minors must wait seven days after a failed knowledge test.
STUDY NOTES
What the DMV says to study
DMV directs applicants to the California Driver's Handbook and its official sample knowledge tests. The official preparation page says the questions are taken from the handbook and advises applicants to read each question carefully.
- Give yourself time to read the handbook instead of trying to learn it all at once.
- Use official sample tests to become familiar with the multiple-choice format.
- Study the reason behind an answer so the rule still makes sense when a question is worded differently.
- Do not use a handbook, phone, or other testing aid during the actual knowledge test.
There are no official 'trick questions'
California DMV's preparation guidance says there is one correct answer and the other choices are wrong or not appropriate for the question. It specifically tells applicants not to overthink the questions because there are no trick questions.
