In what situation should you use your horn while driving?

Using your horn is primarily a tool for ensuring safety on the road. When you alert another driver of your presence, it can prevent accidents, especially in situations where visibility is limited or when another driver is about to enter your path. For example, if a vehicle is making a left turn in front of you and does not see you coming, a beep of the horn can catch their attention and help them realize your presence, allowing them to stop or adjust their maneuver.

Employing the horn to express frustration, signal a traffic violation, or as a means to request someone to change lanes does not align with the intended use. The horn is meant for communication that enhances safety, not for expressing personal emotions or frustrations. Keeping this focused approach to using the horn can significantly contribute to safer driving conditions for everyone on the road.
