How do I prepare for the Arizona CDL knowledge test?
If you are preparing for your first permit, start with general knowledge and the official Arizona instructions below. If your vehicle needs air brakes or combination vehicles, add those federal study sets; for hazardous materials, use the separate hazmat set. Compare the state’s published test rules with its current manual before you test. These practice sets teach federal topics and do not copy the state exam.
This page is study material. It is not the Arizona state exam, and it does not copy state test questions. Check the official Arizona pages below before you test.
| Your situation | Start with… |
|---|---|
| A quick first try | Take a 10-question warm-up |
| Ready for a longer attempt | Take the 50-question general knowledge exam |
| Need state rules or documents | Check the Arizona application steps |
Arizona commercial driver manual (PDF) — link checked . Study its rules alongside our federal-standard bank. Our 50-question exam length is a study setting; use the official counts below for Arizona.
Arizona MVD’s CDL application page and manual checked November 10, 2026 require at least 80 percent on each knowledge test. The knowledge-testing instructions and manual section checked do not print question counts. Use the official manual to choose subjects for your vehicle and endorsements; our federal practice lengths are not Arizona exam lengths.

Federal study sets, not the Arizona exam
Use general knowledge, air brakes, combination vehicles, and hazmat to study the federal topics. Finishing one of those sets does not mean you passed the Arizona test.
