What lights should a school bus use when unloading passengers?

When a school bus is unloading passengers, it is required to activate its red flashing lights and deploy the stop arm. This safety feature is crucial for ensuring the safety of children as they exit the bus and cross the street. The red lights signal to other motorists that they need to stop, as children may be entering or exiting the bus and potentially crossing in front of it. The stop arm further reinforces this warning, providing a clear visual cue to drivers that they must halt their vehicles and give way to the children.

This combination of red flashing lights and the stop arm is mandated by law, emphasizing the importance of these measures in protecting the most vulnerable road users—children. When these safety protocols are followed, the likelihood of accidents decreases significantly, creating a safer environment for school children.
