California CDL Pre-Trip Inspection: Exterior Walkaround Test 2026

The walk-around is a route, not a wander. This California CDL exterior walk-around inspection test follows the standard circuit for 2026 - front, driver side, fuel area, rear of the tractor, coupling, trailer sides, rear doors and lights, back up the passenger side - so nothing gets skipped because you doubled back.

Along the way this CDL exterior inspection practice test covers tires for tread depth, inflation, cuts and mismatched sizes, rims and lug nuts, hub oil seals, suspension springs and mounts, mud flaps, exhaust and frame, doors and cargo securement, and the reflectors and lamps on every corner. It also asks the harder question behind each item: what defect makes the vehicle out of service rather than merely worth watching.

California DMV draws these expectations from the California CDL Manual, which also states the exact number of questions on the pre-trip inspection exam. That figure is a state decision, so look it up rather than guess.
