What does the inspector need to verify about the horn during the vehicle inspection?

The requirement that the horn must be functional and audible is crucial for vehicle safety. During an inspection, the inspector checks that the horn emits a sound loud enough to be heard by other drivers and pedestrians, which is essential for alerting others of the vehicle's presence and preventing accidents. A functioning horn is a vital component of a vehicle's safety features, as it allows the driver to communicate effectively with others on the road.

Ensuring that the horn meets these standards helps maintain a safe driving environment and compliance with state regulations. Without this functionality, a vehicle could pose a danger to both the driver and others, as communication on the road is key to avoiding collisions and other hazards. This is why the audible functionality of the horn is emphasized in the inspection process.
