In which situation is it acceptable to use your horn?

Using the horn is primarily meant for safety purposes and communication on the road. When you alert other drivers of your presence, especially in situations where they may not see you or where there is potential for a collision, it becomes a crucial safety measure. This proper use of the horn can prevent accidents by making your intentions clear and ensuring that you have been noticed.

In contrast, using the horn to greet friends is generally considered unnecessary and can be distracting or annoying. Similarly, expressing anger through horn use can lead to road rage and escalate tensions rather than solve potential issues. Warnings to pedestrians should typically be done in a less aggressive manner, such as slowing down or changing your course, rather than resorting to honking. Therefore, the acceptable use of your horn is to ensure safety and alertness on the road.
