If a vehicle's horn does not work, it triggers what inspection outcome?

When a vehicle's horn does not function, it directly impacts the inspection outcome because a working horn is considered a critical safety feature. The horn is essential for alerting other drivers and pedestrians of the vehicle's presence or to warn them of potential danger. If the horn is inoperative, it undermines the vehicle's ability to communicate effectively on the road, which poses a safety risk.

In a vehicle inspection, each component is assessed for functionality and compliance with safety standards. A non-working horn would therefore lead to a failure outcome since it does not meet the required safety standards necessary for the vehicle to be deemed roadworthy. This highlights the importance of ensuring that all critical systems, including the horn, are fully operational before a vehicle is considered safe for operation in public areas.
