Michigan CDL School Bus: Lights Test 2026

The flashing lights and extended stop arm turn a school bus into a rolling traffic-control device, and the Michigan CDL school bus lights and stop arm test checks that you use them correctly. Timing the yellow and red lights and the stop arm is central to the S endorsement in 2026.

These questions cover when to activate the alternating amber warning lights, when the red lights and stop arm come out, how far ahead of a stop to begin signaling, and what to do when other drivers ignore the signals. You will review why proper light and stop-arm use protects children crossing the road. The Michigan CDL Manual details the signaling sequence these questions test.

Since the school bus endorsement question count is set by the state and can be revised, check your Michigan CDL Manual for the exact figure rather than guessing. Practice this lights and stop arm drill until the signaling sequence is automatic for the Michigan Secretary of State exam.
