What is the purpose of the flashing lights on a school bus?

The purpose of the flashing lights on a school bus is to indicate that students are getting on or off the bus. When the lights are activated, it serves as a clear and visual warning to drivers that they need to exercise caution because children may be crossing the road or are in the vicinity of the bus. This safety measure is critical, as it ensures that other vehicles stop and do not proceed while children are potentially in a hazardous situation.

The flashing lights act as an important deterrent for accidents by alerting drivers to the presence of children who may be unpredictable and difficult to see. This enhances overall safety during school boarding and alighting activities, which can often occur in busy or crowded areas.
