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

Uncoupling a doubles or triples combination reverses the extended coupling sequence, and this Virginia CDL drill walks through disconnecting trailers in the correct order rather than however seems convenient in the moment. Expect questions on uncoupling the rearmost trailer first, then the converter dolly, and finally separating the tractor from the lead trailer, each step requiring its own landing gear positioning and air line disconnection.

This set covers why a driver checks that ground conditions are solid and level before dropping the converter dolly specifically, since a dolly left on soft ground can tip more easily than a full trailer resting on its own landing gear. You will also see material on properly securing disconnected air lines and electrical cables so they do not drag or become damaged once a trailer or dolly is left standing alone.

The Virginia CDL Manual lays out the full reverse sequence and exact question count for this section, and this drill exists to build genuine comfort with a multi-step process that many drivers rarely rehearse enough. Run through uncoupling a full combination repeatedly before your 2026 T endorsement skills test, since sequence errors here are exactly what examiners watch for most closely.
