Arizona CDL practice test

Getting a commercial driver's licence in Arizona starts with the CDL knowledge tests. The content is federal: every state, Arizona included, writes its tests from the FMCSA CDL manual, so the general knowledge test has 50 questions, the endorsement tests have 20 to 30, and the passing score is 80% on each. Arizona Department of Transportation, Motor Vehicle Division administers the test; the rules behind it are published by the FMCSA.

How the Arizona CDL knowledge test works

You take the general knowledge test first; it is required for every CDL class. Class A drivers add the combination vehicles test. Almost everyone takes the air brakes test, because skipping it puts an air brake restriction on the licence. Endorsements (hazmat, tanker, doubles/triples, passenger, school bus) each have their own knowledge test. Pass the tests and you hold a commercial learner's permit; the skills test in a truck comes later.

Fees, appointment rules and test centre locations are set by Arizona; the current ones from Arizona MVD are in the next section. What does not change is the content, and that is what PassRig drills.
