When should you use your horn?

Using your horn is primarily meant for safety and communication with other road users. The correct approach is to use your horn only to alert other drivers of your presence in dangerous situations. This practical guideline protects everyone on the road—by emphasizing warnings, a driver can signal to others to avoid a potential collision or indicate urgency when necessary.

In contrast, using your horn to greet friends on the road, express annoyance, or encourage drivers to speed up does not align with the intended safety function of the horn. Greeting friends may distract you from attention to driving, while using the horn out of annoyance or to rush other drivers can escalate situations and create further risks rather than promote safety. Therefore, reserving horn usage for critical and clear warnings makes the roads safer and more respectful for all users.
