New Jersey CDL Pre-Trip Inspection: Lights Test 2026

Lights are quick to check and easy to fail on. This New Jersey CDL pre-trip lights and signals test runs the whole exterior lighting set: headlights on low and high beam, turn signals front and rear, four way flashers, brake lights, tail lights, clearance and marker and identification lamps, and the reflectors along the trailer.

Questions here cover the order you check them in, why you turn the signals on before you leave the cab, what a cracked or fogged lens means, and how a burned out clearance lamp on a trailer working the I-95 corridor at night turns into a roadside inspection violation.

These items are original topical practice rather than real exam content. The pre-trip inspection question count on the New Jersey written exam is a state figure, not a federal one, so read the 2026 number in your New Jersey CDL Manual. Use this lights and signals drill as a fast daily loop beside the walk around practice.
