Montana CDL Combination Vehicles: Uncoupling Test 2026

Dropping a trailer safely matters as much as hooking one up, and this Montana CDL combination uncoupling test drills the proper sequence for your 2026 Class A prep. You will rehearse parking on firm level ground, lowering the landing gear until it just bears weight, disconnecting and securing the air lines and electrical cord, and then releasing the fifth wheel locking jaws.

This combination vehicle practice set covers chocking the trailer wheels, easing the tractor forward slowly out from under the trailer, and confirming the trailer stays firmly supported. Rushing or skipping a step here is how trailers topple or land on the tractor.

The Montana CDL Manual specifies how many uncoupling questions appear on the combination test, so read it to be certain. Practice the uncoupling order until you can perform it in your head without a stumble, then keep advancing your Montana CDL combination preparation toward test day.
