Minnesota CDL Pre-Trip Inspection: Lights Test 2026

Your lights are how you communicate on the road, and this CDL pre-trip lights and signals practice test for Minnesota makes sure they all work before you roll. Headlights, brake lights, turn signals, four-way flashers, clearance and marker lights, and reflectors are all part of a proper inspection.

You will practice checking that each light functions and is the correct color, that lenses are clean and not cracked, and that turn signals and flashers blink at the right rate. Through Minnesota's dark winters and early sunsets, working lights are not optional, and burned-out lamps are an easy way to fail the 2026 inspection or draw a roadside violation. The Minnesota Commercial Driver's License Manual lists the lighting and signal items your pre-trip must include.

Run these questions until you can verify every lamp and signal from memory, then return to a full pre-trip practice test to put the whole inspection together.
