The primary purpose of the horn on a car is to warn of your presence. It serves as a critical safety feature that helps drivers communicate with other road users, especially in situations where visibility may be limited or when a vehicle may be approaching a hazard. By using the horn, a driver can alert other drivers, cyclists, and pedestrians, helping to prevent accidents and enhance overall road safety.

While signaling vehicles behind or indicating turns has its own importance in road communication, these are specific uses of the car's signaling methods, such as turn signals or brake lights, rather than the primary function of the horn itself. Similarly, while alerting pedestrians is an essential consideration, the broadest and most vital use of the horn is to make your presence known to various road users.
