In what circumstances is it appropriate to activate the bus horn?

Activating the bus horn is appropriate in situations where there is a potential danger or to convey an urgent message about safety. When you are required by law to use the horn, it serves as a critical safety tool to alert others of the bus's presence in circumstances that could lead to accidents or unsafe situations. This can include scenarios where visibility is limited, dangerous conditions may arise, or when the bus is approaching stop signs or intersections where other vehicles may not be aware of the bus's movements.

Using the horn to signal danger ensures that nearby vehicles, pedestrians, or students in the vicinity are alerted and can take appropriate action to maintain safety. This aligns with emergency protocols designed to prevent incidents, making it essential for maintaining security on the road.
