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

Uncoupling a doubles or triples combination reverses the coupling order exactly, and this Wyoming CDL practice test walks through that sequence: setting brakes on each unit, disconnecting the last trailer first, then the dolly, working backward toward the tractor. Expect the exam to test whether you know this order cold, not just the individual actions.

An uncoupling test like this one also covers securing each disconnected unit properly before moving to the next, since an unsecured trailer left mid-sequence is a real hazard, not just a wrong exam answer. Getting this right protects equipment on Wyoming's energy-corridor and linehaul routes alike.

The Wyoming CDL Manual documents the required uncoupling order for multi-trailer combinations in full. Run through this practice test repeatedly ahead of 2026 endorsement testing, pairing it with the coupling material for complete review.
