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

Taking a doubles or triples set apart safely demands the same discipline as building it, and the Maryland CDL doubles triples uncoupling test checks that you have the order right. This 2026 drill covers securing the rear trailer, uncoupling the converter dolly, disconnecting the air and electrical lines in sequence, and separating each unit without letting anything drop.

You will rehearse chocking the trailers before you release them, lowering the dolly's support correctly, and why rushing the teardown risks equipment and people alike. Uncoupling doubles and triples is a step-by-step process, and Maryland examiners expect you to explain it cleanly from the last trailer forward.

Since doubles and triples question totals vary by jurisdiction, confirm the number in your latest Maryland CDL Manual before test day. Practice this uncoupling sequence until it flows without hesitation, and you will complete the hands-on side of your CDL doubles and triples preparation.
