Virginia CDL Combination Study Tips from Top Performers

1Start with Virginia DMV's CDL Knowledge Exams page and the Virginia Commercial Driver's Manual Section 6-1 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, leak, and trailer brake test 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.
5Confirm Virginia CLP documents, fees, medical certification, ELDT status, one-business-day retest limit, and testing requirements on DMV pages before testing.
