At what distance should a horn be audible?

A horn should be audible at a distance of 200 feet to ensure that it can effectively alert pedestrians and other drivers to the vehicle's presence. This distance is crucial for safety, particularly in school zones or areas where pupil activity buses operate, as it provides sufficient warning for individuals in close proximity to react accordingly.

Being heard from this distance helps in preventing accidents and enhances the overall safety of the environment where the bus is operating. This standard is typically in place to align with safety regulations and best practices for pupil transport, ensuring that the sound emitted by the horn is loud enough to be perceptible without being excessively loud, which could disturb the community or distract from important communications.
