Colorado CDL Pre-Trip Inspection: Engine Compartment Test 2026

Under the hood, the pre-trip inspection has a long list of items, and the Colorado CDL exam expects you to name and check each one. This Colorado CDL pre-trip engine compartment test covers fluid levels, belts and hoses, the steering components, and the leaks or wear that signal a truck is not ready to roll.

This part of the inspection protects you on demanding Colorado hauls in 2026. Before climbing toward the Continental Divide, a driver checks the engine compartment because a low coolant level or a cracked belt can turn a mountain grade into a breakdown, or worse. We cover how to inspect the power steering, water pump, alternator belts, and the hoses that keep the engine alive.

Lean on your Colorado CDL Manual for the complete engine compartment checklist, and since inspection question totals are set by the state, verify the count there. Repeat this engine compartment test until every under-hood item is firmly in your memory.
