When is it appropriate to use your horn while driving?

Using your horn while driving is appropriate primarily as a means to alert other drivers of your presence when necessary. This is an essential safety practice that helps prevent collisions and ensures that all road users are aware of each other, particularly in situations where visibility might be compromised or when another driver may not see you.

In scenarios such as approaching an intersection where another vehicle might not yield or when another driver is encroaching upon your lane unexpectedly, using the horn can serve as a vital warning, prompting the other driver to take corrective action. This use of the horn is rooted in promoting safety for everyone on the road, which is a fundamental aspect of defensive driving.

Using the horn to greet friends or to express frustration, however, does not contribute to road safety and may cause confusion among other drivers. Signaling when overtaking can be done through your vehicle's turn signals rather than the horn, as it is essential to communicate intentions clearly and in a manner that adheres to driving laws and etiquette. Prioritizing safety and clear communication on the road should always guide the use of your horn.
