Arizona CDL permit test: what to expect
The written exam most people call the Arizona CDL permit test is the general knowledge test, and passing it is what gets you a commercial learner's permit rather than the license itself. You need 80% to pass, a federal standard that is the same in every state. The number of questions is set by Arizona, and our practice tests use the common 50-question format.
Once you hold the permit you have to keep it for at least 14 days before you are allowed to attempt the skills test, so it is worth sitting the written exam as early as you can. Practice below until you are clearing Arizona's standard comfortably rather than scraping it.

5 Arizona CDL Practice Questions and Answers
Here are 5 sample Arizona general knowledge questions with the right answer and a quick explanation for each. Read through them, then take the quiz above to see how you do without looking.
1. How does knowing the sound of your engine help with basic vehicle control?
- A. It warns you of an imminent tire blowout.
- B. It helps you time your shifts without constantly staring at the tachometer. (correct answer)
- C. It tells you when the air tanks are fully pressurized.
- D. It automatically regulates the vehicle's speed.
Why: Experienced drivers learn to recognize the sound of the engine. By listening to the pitch of the engine, you can determine when to upshift or downshift without taking your eyes off the road.
2. You have turned on your turn signal to switch lanes, but you suddenly realize there is a vehicle in your blind spot and you cannot safely move. What must you do regarding your communication?
- A. Leave the signal on and slowly force your way over.
- B. Leave the signal on until the vehicle moves out of your way.
- C. Cancel the turn signal immediately so you do not send a false message that you are still merging. (correct answer)
- D. Turn on your four-way flashers.
Why: If you abort a maneuver, you must cancel your turn signal immediately to avoid confusing other drivers into thinking you are still going to change lanes.
3. Which type of vehicle is most likely to be blown over in high winds?
- A. A fully loaded flatbed.
- B. A heavy tanker truck.
- C. A lightly loaded or empty tractor-trailer. (correct answer)
- D. A loaded bobtail.
Why: Lightly loaded or empty combination vehicles stand a much greater chance of being blown over by strong winds than fully loaded vehicles.
