When should you use your vehicle's horn?

Using your vehicle's horn is an important element of safe driving, primarily serving the purpose of alerting others to your presence to prevent potential accidents. Utilizing the horn to inform another driver of your presence is a critical safety measure, especially in situations where visibility is compromised, such as when approaching a blind intersection or when another vehicle is encroaching on your space. This use of the horn helps ensure that everyone on the road is aware of each other's movements, which can significantly reduce the risk of collisions.

In contrast, greeting friends on the road may distract both you and others, leading to unsafe driving behavior. Similarly, using the horn out of anger is not constructive and can escalate tensions, potentially leading to aggressive driving situations. Finally, while signaling a pedestrian is important, drivers should primarily use their horn to communicate with other vehicles. Therefore, the correct usage of the horn lies in promoting safety and awareness on the road.
