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

Breaking down a set of doubles or triples must happen in the right order, and the uncoupling topic on the Connecticut CDL doubles and triples test drills that sequence. This 2026 practice set covers uncoupling the rear trailer and dolly first, lowering the landing gear, securing each unit, and working forward so no trailer is ever left unsupported.

Expect questions on why you park the rig in a straight line before uncoupling, how to lower the dolly and disconnect it safely, and why the order of separation matters when several trailers are linked. Connecticut T endorsement candidates need this procedure clear to avoid dropping a trailer in the yard.

The Connecticut CDL Manual details the doubles and triples uncoupling steps and states the exact number of questions, so there is no guessing involved. Repeat this Connecticut CDL doubles and triples uncoupling test until you can separate a multi-trailer combination safely and in the correct order every time.
