Colorado CDL Pre-Trip Inspection: Exterior Walkaround Test 2026

The exterior walk-around is where you circle the vehicle and prove it is roadworthy, and the Colorado CDL skills exam watches it closely. This Colorado CDL pre-trip exterior walk-around test covers the tires, wheels, lights, mirrors, suspension, and coupling area, in the systematic path an examiner expects you to follow.

A careful walk-around catches trouble before Colorado roads can punish it in 2026. Before a long run down I-25, a driver checks tire condition and inflation, looks for cracked wheels and loose lug nuts, and confirms every light works, because small defects grow fast under highway miles and mountain weather. We cover what to inspect at each point around the truck.

The Colorado CDL Manual describes the full exterior inspection route you must be able to demonstrate, and because the question count varies by state, check it there. Rehearse this exterior walk-around test until you can circle the whole vehicle and call out every item from memory.
