Mississippi Class A CDL applicants who want to drive combination vehicles must pass the Combination Vehicles knowledge material along with any other required CDL tests. Study Mississippi CDL Manual Section 6: fifth wheel and kingpin coupling, tug and visual checks, air/electric lines, landing gear, trailer brakes, off-tracking, rollover, backing, trailer skids, jackknife recovery, and safe speed and space management. Federal CDL rules require at least 80% correct on each knowledge test, and failing the combination portion blocks Group A CLP/CDL issuance.

Mississippi CDL Combination Study Tips from Top Performers

1Start with Mississippi CDL Manual Section 6 before drilling practice questions.
2Turn coupling into a checklist: inspect fifth wheel, align, set trailer height, back under, tug test, visual lock check, connect lines, charge air, test brakes, raise landing gear, and remove chocks.
3Memorize red emergency/supply and blue service glad-hand functions, then practice crossed-line and leak scenarios.
4Study 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.
5Before testing, confirm Mississippi CLP documents, fees, medical self-certification, ELDT status, and portal or appointment rules on official Driver Service Bureau pages.
