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

Taking apart a set of doubles or triples safely means reversing the coupling process in the right order, and this CDL doubles and triples uncoupling practice test for Minnesota drills the sequence. You will uncouple the rear trailer from the dolly, secure the dolly, and separate each unit without letting anything roll or drop.

Practice covers setting trailer brakes and chocking wheels before you disconnect, lowering landing gear at the right moment, unhooking the dolly's air and safety chains in order, and parking each trailer where it will stay put. With multiple units, the chances to make a costly mistake multiply, so the discipline of a fixed order protects you. The Minnesota Commercial Driver's License Manual spells out the uncoupling steps for these combinations.

Because these skills sit under the T endorsement, work the 2026 questions until the procedure is automatic, then loop back to a full doubles and triples practice test to see it all connect.
