About the Indiana CDL lights and signals test

Every lamp on a commercial vehicle has a job, and the Indiana CDL pre-trip lights and signals test makes sure you can check them all. This 2026 study set covers headlights, brake lights, turn signals, marker and clearance lamps, and the reflectors that keep a big rig visible after dark.

Focus on confirming that each light is clean, unbroken, and the correct color, that turn signals and four-way flashers work front and rear, and that brake lights respond when the pedal is pressed. Indiana's commercial driver license manual details the lighting inspection, and because the number of pre-trip questions is set by the state, check your Indiana CDL Manual for the exact figure this year.

Working lights are both a legal requirement and a pre-trip pass point on the road to your CDL. Run this lights and signals drill until checking every lamp becomes an automatic habit.

Every question traces back to the Indiana CDL Manual - skim the right-of-way and signs chapters before your retake.
