Alaska CDL Combination Vehicles: Uncoupling Test 2026

Separating a tractor from a trailer safely is as procedural as hooking up, and the Alaska CDL combination uncoupling test makes sure you follow the order. This 2026 drill covers lowering the landing gear, disconnecting the air lines, and pulling the fifth-wheel release at the right moment.

Questions walk through chocking or securing the trailer, easing tractor weight off the fifth wheel, disconnecting the glad hands, and driving out slowly once the connection is clear. Do these steps out of sequence and the trailer can drop or the landing gear can buckle, which is why the Alaska DMV includes uncoupling in the combination endorsement.

The uncoupling sequence and the exact combination question count are both in the Alaska CDL Manual. Practice this combination vehicle practice test until you can uncouple a trailer confidently and in the correct order.
