Vermont CDL Combination Vehicles: Uncoupling Test 2026

Uncoupling a trailer safely follows its own sequence, and this Vermont CDL combination uncoupling test covers each step the Vermont DMV expects a Class A driver to perform correctly. That starts with chocking the trailer wheels, lowering the landing gear to just touch the ground, and disconnecting the electrical and air lines before releasing the fifth wheel locking lever.

This uncoupling test also covers pulling the tractor forward slowly and smoothly once the fifth wheel is released, checking that the trailer remains stable on its landing gear, and securing the glad hands and electrical line properly so they are not dragged or damaged. Rushing any of these steps is exactly the kind of shortcut this exam is built to catch.

Run through this combination uncoupling test until the sequence is second nature in either direction. Vermont CDL applicants who master uncoupling procedure alongside coupling procedure walk into the Vermont DMV combination exam fully prepared for both halves of the skill.
