Montana CDL Combination Vehicles: Inspecting the Coupling Test 2026

A coupling can look connected and still be wrong, so this Montana CDL combination inspecting the coupling test teaches you to prove it for 2026. You will crouch and check that the fifth wheel jaws are fully closed around the kingpin, that there is no daylight gap between the fifth wheel and the trailer apron, and that the locking lever is seated with the safety catch in place.

This combination vehicle practice drill also covers confirming the fifth wheel is not tilted or cracked, the mounting is tight, and the air and electrical lines are secured with slack to turn. On a Class A rig these checks are what stand between you and a dropped trailer.

The Montana CDL Manual states how many coupling-inspection questions the combination exam includes, so read it to be sure. Rehearse this inspection until you can spot a bad coupling instantly, then push on with your Montana CDL combination preparation.
