Baltimore, MD - Aug. 29, 2022 - School starts today for many students in Baltimore! Learn and obey the "alternately flashing warning light" system that school bus drivers use to alert motorists:

Yellow flashing lights indicate that the bus is preparing to load or unload children.
Motorists should slow down and prepare to stop vehicles.

Red flashing lights and extended stop arms indicate the bus has stopped, and that children are getting on or off.

Motorists approaching from either direction must wait until the red lights stop flashing before proceeding.
