Kentucky CDL Combination Vehicles: Inspecting the Coupling Test 2026

The connection between tractor and trailer must be checked before you roll, and this Kentucky CDL combination inspecting the coupling test covers exactly what to look for. You will drill checking that the fifth wheel jaws are locked around the kingpin, that there is no gap between the fifth wheel and the trailer apron, and that the locking lever is in place.

Expect questions on inspecting the mounting bolts, the release arm position, and the safety latch, plus confirming the landing gear is fully raised. Catching a bad coupling during inspection prevents a dropped trailer, which is why Kentucky commercial drivers scrutinize it in 2026.

Each coupling inspection point is described in your Kentucky Commercial Driver License Manual, so study that section first. Keep running this inspecting the coupling test until every checkpoint at the fifth wheel is something you verify automatically.
