Alabama CDL Doubles & Triples: Uncoupling Doubles/Triples Test 2026

Taking a set of doubles or triples apart follows a careful order, and the Alabama CDL doubles and triples uncoupling test drills it step by step. You uncouple in reverse of assembly, securing each trailer, handling the converter dolly, and resetting the shut-off valves so the remaining units keep their brakes, a sequence the 2026 exam expects you to know.

The uncoupling questions reward patience. You will lower landing gear onto solid ground, disconnect air and electrical lines in the right order, store the dolly safely, and confirm each parked trailer cannot roll before moving on to the next.

Rehearse these uncoupling items alongside the coupling and converter dolly drills so both directions feel routine. The Alabama CDL Manual lays out the multi-trailer uncoupling steps ALEA references, so let this doubles and triples uncoupling session make breaking down a set as controlled as building one.
