Mississippi CDL Combination Vehicles: Uncoupling Test 2026

Dropping a trailer wrong can send it crashing to the ground, and these CDL combination uncoupling questions rehearse the safe order for setting one down. Uncoupling procedure is a regular subject on the Mississippi CDL combination test, so a 2026 candidate should have this sequence fully memorized.

The drill walks through positioning the rig and easing tension off the fifth wheel, chocking the trailer wheels, lowering the landing gear until it just bears weight, disconnecting the air lines and electrical cord and stowing them, releasing the fifth wheel lock, and pulling slowly clear. Each step guards against a dropped or rolling trailer.

Since combination question totals vary by state, read yours in the Mississippi CDL Manual and follow its uncoupling checklist in order. Repeat these uncoupling questions across 2026 until the routine is automatic, and you will set a trailer down safely whenever the Mississippi DPS examiner asks you to demonstrate it.
