North Carolina CDL Combination Vehicles: Inspecting the Coupling Test 2026

The coupling between tractor and trailer is a life-safety point, and this North Carolina CDL practice test for 2026 drills how to inspect it. You will check that the fifth wheel is properly greased and secure, that the locking jaws wrap fully around the kingpin, and that no gap shows between the fifth wheel plate and the trailer apron.

Questions cover looking for bent or loose mounting parts, confirming the release arm is in the locked position, and making sure the safety latch is closed. Inspecting the coupling is a required skill in the combination portion of the North Carolina CDL and a daily habit for Class A drivers.

The combination question count is not fixed, so confirm it in your North Carolina CDL Manual instead of assuming. Practice this inspecting the coupling test until you can spot a bad connection at a glance well before your 2026 exam.
