To what distance should a vehicle's horn be audible?

A vehicle's horn should be audible at a distance of 200 feet. This standard ensures that the horn can effectively alert pedestrians, cyclists, and other vehicles of the driver's presence, particularly in situations where visibility may be compromised or when a warning is necessary to prevent an accident. The purpose of having a horn that is detectable from this distance is to enhance safety on the road by communicating the vehicle's approach or intentions to others.

This visibility also serves to enforce the idea that drivers must be proactive in ensuring their presence is known to avoid potential collisions, contributing to overall road safety. This distance is commonly recognized in traffic laws and regulations, highlighting its significance in daily driving scenarios.
