When should you use your horn while driving?

Using the horn while driving is primarily intended as a safety measure. It serves as a tool to alert other drivers of your presence, especially in situations where visibility may be limited or when another driver may not be aware of your approach. For example, if a vehicle is about to change lanes without seeing you or if you need to warn someone of a potential collision, honking the horn can help prevent an accident.

This approach to using the horn underlines its purpose as a communication device to enhance road safety, rather than for casual or emotional expressions. Instead of using the horn for greetings, frustration, or non-emergent situations, it should be reserved for scenarios where immediate awareness or reaction is necessary among drivers and pedestrians.
