New Hampshire CDL Combination Vehicles: Inspecting the Coupling Test 2026

A coupling can look fine and still be unsafe, which is why the New Hampshire CDL combination inspecting the coupling test teaches you to check it with your eyes and hands, not just a glance. This 2026 drill covers getting under to view the locking jaws around the kingpin, confirming the fifth wheel is fully seated, and making sure the release arm is properly engaged.

You will study what a visible gap between fifth wheel and trailer means, how to spot a jaw that closed on the shank instead of the pin, and why the safety latch over the release handle has to be down. This CDL combination inspecting the coupling routine is the difference between a driver who trusts the tug test alone and one who truly verifies the connection in New Hampshire.

Because inspection points can vary, confirm the exact items in your New Hampshire Commercial Driver's Manual before test day. Run this inspecting the coupling set until the checks are second nature, and your combination vehicle preparation will be far stronger.
