Rhode Island CDL Combination Vehicles: Uncoupling Test 2026

Separating a tractor from a trailer safely takes as much care as joining them, and this Rhode Island CDL combination uncoupling test covers the full sequence. Lowering the landing gear, easing the tractor forward to relieve tension, disconnecting the air lines and electrical cord, unlocking the fifth wheel, and pulling clear each have a correct order. A 2026 CDL combination applicant must get that order right to leave a trailer standing safely.

Questions here address why you chock the trailer wheels first, when to lower the landing gear so it bears the load, and how to secure the glad hands once they are disconnected. The Rhode Island CDL Manual lays out the uncoupling steps plainly, so use it as the script behind every answer.

The number of uncoupling questions is decided by the state, so check the current Rhode Island CDL Manual for it. Repeat this combination practice test until a safe, orderly uncoupling comes naturally before your 2026 Rhode Island exam.
