What should a vehicle's horn do?

Produce loud noise
Work
Be muffled
Play music

The correct answer is: Work

The primary purpose of a vehicle's horn is to serve as a warning device to alert other drivers, pedestrians, or cyclists of the vehicle's presence, especially in situations where visibility is limited or where a potential hazard exists. Therefore, the horn should effectively function whenever it is required. While producing a loud noise is an aspect of functionality, the focus here is on the fact that the horn must work reliably to serve its intended purpose. A non-functioning horn cannot fulfill its role in enhancing safety on the road. The concept of the horn being muffled or playing music does not align with its design and use, as these would detract from its effectiveness as a safety tool.
