Michigan CDL Combination Study Tips from Top Performers

1Start with the Michigan Commercial Driver License Manual and focus on combination-vehicle material before drilling practice questions.
2Memorize the Michigan Group A structure: 70 General Knowledge questions plus a 20-question Combination Vehicle test, with 80 percent required to pass each knowledge test.
3Turn the coupling sequence into a checklist: inspect fifth wheel, align, check trailer height, back under, tug test, visual lock check, connect lines, charge air, test brakes, raise landing gear, and remove chocks.
4Memorize red emergency/supply and blue service glad-hand functions, then practice crossed-line and leak scenarios.
5Study control risks as cause-and-effect: speed plus high center of gravity increases rollover, hard braking can lock trailer wheels, and off-tracking makes trailer wheels cut inside turns.
6Before testing, confirm Michigan documents, fees, medical self-certification, ELDT status, CLP timing, retake rules, and skills-test provider details on the SOS CDL page.
