How do you verify the functionality of the horn during an inspection?

Verifying the functionality of the horn during an inspection primarily involves pressing the horn button to ensure that it emits sound. This action directly assesses whether the horn is operational, as the primary purpose of a vehicle's horn is to alert other drivers and pedestrians of the vehicle's presence or to communicate intentions on the road.

While checking for visual damage, testing with a multimeter, or inspecting the wiring for wear may be part of a more comprehensive evaluation or maintenance procedure, they do not provide immediate confirmation of the horn's functionality. The most effective and straightforward method to confirm if the horn is working is to actively engage it and listen for a sound output. This approach ensures that the horn is not only intact but also confirms its readiness for use in real driving situations.
