When is it acceptable to use your horn on the road?

Using your horn is primarily regarded as a safety tool meant to alert other drivers to potential hazards or dangers present on the road. It serves as a warning signal and can effectively communicate that something may not be safe, such as an upcoming collision or an unexpected obstruction. When used appropriately, the horn can help prevent accidents and enhance road safety by drawing attention to issues that other drivers may not be aware of.

In contrast, using the horn to greet other drivers may be seen as unnecessary and could potentially be distracting or misinterpreted. Signaling a lane change typically doesn’t require the use of the horn, as turn signals serve that purpose effectively. Likewise, requesting the right of way is not an appropriate use of the horn; right of way laws are established to regulate who proceeds first in various driving situations, and using the horn may not have the desired effect and could lead to confusion or unsafe conditions.
