How the Maine 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 Maine; the current ones from Maine BMV are in the next section. What does not change is the content, and that is what PassRig drills.
