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

Taking apart a set of trailers safely follows its own order, and the Alaska CDL doubles and triples uncoupling test confirms you know it. This 2026 drill covers uncoupling the rear trailer, handling the converter dolly, and securing everything left behind.

Expect questions on lowering the landing gear, disconnecting air and electrical lines in the right sequence, releasing the dolly from the trailer, and making sure each uncoupled unit is chocked or braked. Rushing or reversing these steps can drop a trailer, which is why the Alaska DMV includes uncoupling in the doubles and triples endorsement.

The uncoupling steps and the exact doubles and triples question count both live in the Alaska CDL Manual. Practice this cdl doubles and triples test until you can break down a multi-trailer rig in the correct order every time.
