What is the primary purpose of the vehicle's horn?

The primary purpose of a vehicle's horn is to alert other drivers of your presence. This function is vital for ensuring road safety, as it allows a driver to communicate with others on the road, especially in situations where visibility is limited or where another driver may not see your vehicle. The horn serves as a warning signal to help prevent accidents and enhance awareness among all road users.

Using the horn to indicate your presence is particularly important in scenarios such as navigating through blind spots, approaching intersections, or warning drivers who might inadvertently encroach into your lane. By sounding the horn, drivers can help make others aware of their vehicle's position, promoting safer driving practices.
