What does a functioning horn indicate during a series of inspections?

The proper functioning of the horn is primarily a safety feature that helps alert other drivers and pedestrians of the bus's presence. It serves as a critical means of communication on the road, allowing the driver to signal other road users when necessary, particularly in situations where visibility may be impaired or where the risk of collision is present. Ensuring that the horn is in working order is essential for the safety of both the bus occupants and those around it.

While other aspects, such as battery charge or bus readiness, are important to consider during inspections, they do not specifically reflect the core purpose of the horn. The horn specifically addresses safety protocols and enhances the visibility of the bus on the road, making it an essential component of safe driving practices.
