When should you use your horn while driving?

Using your horn to alert other drivers of an imminent danger is appropriate because it serves as a crucial safety measure on the road. The primary function of a vehicle's horn is to communicate with other road users, especially in situations where visibility is limited or when another driver may not be aware of a potential hazard. For example, if another vehicle is about to collide with yours or if a pedestrian is in your path, honking can grab their attention and help prevent an accident.

In contrast, indicating your presence merely for awareness, expressing frustration, or using the horn to signal a turn can lead to misunderstandings or escalate tensions on the road, which might not assist in keeping everyone safe. Therefore, the correct and most responsible use of the horn centers on safety and alerting others to avoid potential dangers.
