New Jersey CDL Pre-Trip Inspection: Cab Test 2026

Before the truck moves an inch, the cab has to check out. This New Jersey CDL pre-trip cab start and gauges test covers the in cab portion: seat and mirror adjustment, seat belt condition, the parking brake set, the transmission in neutral, and then the start up itself with every gauge and warning light watched as it settles.

The drill asks what oil pressure should do within seconds of a start, what the ammeter or voltmeter tells you, when the coolant temperature should reach normal, and which warning lights are supposed to go out and which are not. It also covers checking the steering play, the horn, the wipers and washers, the heater and defroster, and the emergency equipment stowed in the cab.

These are original items describing the routine in your New Jersey CDL Manual. That manual carries the exact 2026 pre-trip question count, which varies by state, so read it there rather than guessing at a number.
