Is a horn that works but is not audible 300 feet away a cause for failure?

The assertion that a horn that works but is not audible from 300 feet away is not a cause for failure is based on the specific requirements set forth for vehicle safety inspections. According to these guidelines, while a vehicle's horn must be functional, it is not a strict requirement for it to be audible from a distance of 300 feet. Instead, the focus is on whether the horn can be used effectively in emergency situations to alert others of the vehicle's presence.

In practice, if the horn can be heard at a reasonable distance to serve its purpose, it would pass inspection. Therefore, the correct understanding is that there must be a reasonable expectation of the horn's effectiveness without necessarily meeting the 300-foot audibility threshold. This context helps clarify the standards inspectors follow during assessments, reinforcing the principle that while functionality is key, the specific distance requirements cited do not inherently dictate a failure if the horn is operable.
