Maryland CDL Combination Vehicles: Uncoupling Test 2026

Separating a tractor from its trailer safely is just as procedural as coupling, and the Maryland CDL combination uncoupling test checks that you have the order down. This 2026 drill covers lowering the landing gear, disconnecting the air lines and electrical cord, unlocking the fifth-wheel jaws, and easing the tractor forward so the trailer settles without dropping.

You will rehearse chocking or otherwise securing the trailer before you release it, why you lower the landing gear only until it takes weight, and how rushing this sequence can slam a trailer to the pavement. Careful uncoupling protects both the equipment and everyone nearby, and Maryland examiners expect you to explain every step.

Because combination-question counts are a state matter, look to your latest Maryland CDL Manual for the precise number. Practice this uncoupling sequence until it runs smoothly from start to finish, and you will round out the hands-on side of your CDL combination preparation.
