When should you use your car's horn?

Using your car's horn primarily serves as a safety tool to alert other drivers of your presence, especially in situations where you feel your safety or the safety of others may be compromised. This includes instances where another vehicle may not see you as you approach an intersection, or if a vehicle is drifting into your lane. The horn should be used to communicate necessary caution, thereby helping to prevent accidents.

When it comes to using the horn for other reasons, such as expressing frustration or signaling pedestrians, these actions can lead to misunderstandings or escalate tensions on the road. Inappropriate use of the horn can also contribute to road rage. Therefore, the emphasis should always be on using the horn judiciously and primarily for safety purposes. In emergencies, the horn can alert others to a potentially dangerous situation, but it is essential to remember that it is most effective and intended for safety-related communication on the road.
