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

Taking a doubles or triples rig apart in the wrong order can drop a trailer or a dolly, and these CDL doubles and triples uncoupling questions rehearse the safe sequence. Uncoupling procedure is a regular topic on the Mississippi doubles and triples exam, so a 2026 candidate should know it cold.

The drill walks through chocking the trailer wheels, lowering the landing gear, disconnecting the air and electrical lines in the right order, releasing the fifth wheel or dolly coupling, unhooking the safety chains, and easing the tractor and lead trailer clear one unit at a time. Each step guards against a dropped or rolling trailer or dolly.

Since doubles and triples question totals vary by state, confirm yours in the Mississippi CDL Manual and follow its uncoupling order exactly. Repeat these uncoupling questions through 2026 until the routine is automatic, and you will break a multi-trailer rig down safely whenever the Mississippi DPS examiner asks.
