§ 169.442 — School Bus Signals

Plain-Language Summary

School buses must have stop-signal arms, flashing amber warning lights, and flashing red lights. The amber lights warn you the bus is about to stop. The red lights and stop arm mean you must stop. Buses may also have exterior warning systems and white strobe lamps.

Practical Notes
When you see a school bus with amber lights flashing, slow down and prepare to stop. When the red lights flash and the stop arm is out, you must stop and wait until they are turned off.
