How far away should a car horn be heard?

A car horn should be audible from a distance of 200 feet under normal conditions. This distance is established to ensure that drivers and pedestrians can hear the horn and take necessary actions for safety. The horn is an important safety feature that alerts others to the presence of a vehicle, particularly in situations where visibility may be limited, or when a driver needs to warn another road user of their presence.

Horns are designed to be loud enough to transmit sound over this distance to provide adequate warning, allowing for safer interactions between vehicles and vulnerable road users. While the other distances provided are lower than the specified 200 feet, they do not meet the required standards for ensuring effective communication on the roadways. Thus, the 200-foot measure is critical for maintaining safety on the roads.
