Minnesota CDL Pre-Trip Inspection: Engine Compartment Test 2026

With the hood up, there is a specific list to work through, and this CDL pre-trip engine compartment practice test for Minnesota covers it. You will check engine oil and coolant levels, power steering and windshield washer fluid, the condition of belts and hoses, and the wiring and mounting of components like the alternator and water pump.

Practice covers spotting leaks under the engine, checking that belts have proper tension and are not frayed, confirming hoses are secure and not cracked, and making sure nothing is loose or rubbing. Examiners expect you to name each part and say what you are looking for, so vague answers lose points on the 2026 skills test. Your Minnesota CDL Manual details the engine compartment inspection items you must cover.

Drill these questions until you can walk the engine compartment from memory, then continue to the exterior walk-around to keep your pre-trip inspection complete.
