What is the meaning of a flashing red light on a school bus?

A flashing red light on a school bus signifies that all traffic must stop. This is crucial for the safety of children who are either getting on or off the bus. The law requires drivers to stop when they see a flashing red light and/or an extended stop sign on a school bus, regardless of the direction from which they are approaching. This is designed to protect children, who may be crossing the street or walking in the area surrounding the bus.

The purpose of this signal is to ensure that all vehicles—including those behind and those approaching from the opposite direction—come to a complete stop until the red lights are turned off and the bus resumes its typical operation. Understanding this signal is vital for maintaining safety in school zones and around buses, as it helps prevent accidents involving children.
