Michigan CDL Practice Tests - All Endorsements

The practice tests above draw from the same source Michigan tests you on, the Michigan Commercial Driver License Manual. Read it first, then use these questions to find your weak spots.

The written exam behind all of it is the CDL General Knowledge test. It runs 50 questions, and you pass at 80 percent, which works out to 40 correct out of 50. That standard comes from the FMCSA, so it holds in every state, not just Michigan. Clearing it earns your Commercial Learner’s Permit, which is why a Michigan CDL permit practice test and a general knowledge practice test describe the same work. Class A, B, and C applicants all sit for this one written test. Your class gets decided later, by the skills test and the vehicle you drive.

Expect questions on pre-trip vehicle inspection, basic vehicle control, shifting, managing space and speed, spotting hazards early, and handling emergencies like brake failure or a skid. Keep working a topic until the logic feels automatic instead of memorized.

Detroit’s auto industry keeps freight moving harder than in most states. Parts runs and finished-vehicle hauling fill the I-75, I-94, and I-96 corridors, and a large share of it crosses into Canada at the Detroit-Windsor gateway. Drivers headed for those lanes should prioritize the Combination Vehicles and Air Brakes endorsements early, since air-braked tractor-trailers dominate the work, while anyone chasing fuel or chemical loads will want to plan for the Tanker or HazMat tests.

Those endorsements, Air Brakes, Combination Vehicles, HazMat, Tanker, Doubles/Triples, Passenger, and School Bus, are separate knowledge tests, each with its own topics to learn.
