When is it acceptable to use your horn?

Using your horn is primarily a safety tool designed to alert others to prevent accidents. It's most appropriate in emergency situations where immediate attention is needed to prevent a potential collision or dangerous scenario. The rule of thumb is that the horn should be reserved for warnings or alerts to other drivers, rather than for casual interactions or expressions of frustration.

In many jurisdictions, excessive use of a horn, such as for greeting friends or expressing frustration at other drivers, is discouraged, as it can contribute to road rage and a hostile driving atmosphere. This reinforces the notion that a horn is a signal meant to enhance safety on the road. Thus, limiting its use strictly to emergencies aligns with safe driving practices and ensures that the horn is used effectively and appropriately.
