Tennessee CDL Combination Vehicles Study Tips from Top Performers

1Memorize the Tennessee/Federal Class A threshold: 26,001 pounds or more GCWR and a towed unit over 10,000 pounds GVWR.
2Practice the coupling sequence until fifth wheel setup, kingpin lock, tug test, no-gap visual inspection, air/electric connections, and landing gear checks are automatic.
3Know red emergency/supply and blue service glad hands, and understand what happens when trailer air is lost.
4Study off-tracking, trailer swing, backing, and right-turn clearance because scenario questions often test trailer path judgment.
5Treat trailer skids and jackknife recovery as safety-critical: prevent wheel lockup, release locked brakes, and reduce speed before curves or slippery areas.
