When is it appropriate to use your horn while driving?

Using the horn is an important safety feature in vehicles, and it should be utilized primarily to enhance safety on the road. The appropriate time to use your horn is when it is necessary to alert other drivers or pedestrians of your presence to prevent potential accidents. For instance, if another vehicle is swerving into your lane or if a pedestrian is about to step into the roadway without noticing your vehicle, using the horn can effectively communicate your presence and help to avert danger.

In contrast, using the horn to express frustration or to signal to a friend might distract other drivers or create confusion, which can lead to hazardous situations. Similarly, alerting pedestrians for fun does not serve a practical safety purpose and can be misinterpreted, potentially causing alarm or unease. Therefore, the primary function of the horn should always be to maintain safety on the road.
