Maine CDL Doubles & Triples: Coupling Doubles/Triples Test 2026

Coupling a set of doubles or triples follows a strict order, and the Maine CDL doubles and triples coupling test makes sure you never skip a step in 2026. This drill walks the full sequence for connecting multiple trailers and dollies safely.

You will practice coupling the tractor to the first trailer, positioning the converter dolly, backing the second trailer over the dolly kingpin until the jaws lock, securing every glad hand and safety chain, and confirming each connection with a tug test before moving. Get the order wrong on a Maine yard and a trailer can separate on the road. A methodical CDL doubles and triples coupling drill fixes the correct sequence in your hands.

Because the graded count is a state figure, look it up in your Maine CDL Manual. Once coupling doubles and triples is automatic, continue through the rest of your Maine CDL multi-trailer drills.
