What is the minimum audible distance for a horn on a motor vehicle?

The minimum audible distance for a horn on a motor vehicle is 200 feet, which is significant for ensuring safety on the roads. This requirement is in place to ensure that the sound of the horn can adequately alert pedestrians, cyclists, and other drivers of a vehicle's presence or intention to signal, particularly in potentially hazardous situations. Having a horn that can be heard from this distance enhances communication on the road and helps prevent accidents by increasing awareness.

While the other distances provided may seem plausible, they do not meet the standards set forth for vehicle safety. A horn that can only be heard at shorter distances may not provide sufficient warning or alert others in time to act appropriately when needed. This standard reflects the importance of visibility and audible cues in the overall safety regulations for motor vehicles.
