New Hampshire CDL Pre-Trip Inspection: Lights Test 2026

Being seen and signaling clearly keeps a big truck out of trouble, and the New Hampshire CDL pre-trip lights and signals test makes sure your lighting checks out. This 2026 drill covers headlights on both beams, turn signals, brake lights, marker and clearance lamps, reflectors, and the four-way flashers you rely on when stopped.

You will practice confirming that each lamp works and shows the correct color, that reflectors are present and clean, and that turn and brake signals respond properly. These CDL pre-trip lights and signals checks matter every day and doubly so in New Hampshire's dark winter afternoons, when a burned-out marker light can hide a trailer from other drivers.

Since the exact lighting requirements can vary, verify them in your New Hampshire Commercial Driver License Manual before test day. Run this lights and signals set until every lamp and signal check is routine, then continue finishing out your New Hampshire pre-trip inspection preparation.
