When is it appropriate to use your vehicle's horn?

Using your vehicle's horn is an important tool for communication while driving, primarily aimed at enhancing safety on the road. The appropriate use of the horn is to alert other drivers of your presence in a safe manner. This means that when you are in situations where visibility is limited or when another driver may not see you, a brief tap on the horn can help prevent potential accidents. For example, if you are approaching an intersection where another driver might not notice you, using the horn can serve as a warning that you are there and may help them make safer decisions.

The other choices do not align with safe driving practices. Expressing frustration with another driver can escalate tensions and lead to road rage, which is counterproductive. Signaling your intention to change lanes is typically done using turn signals, which are designed for that purpose. Finally, using the horn to entertain passengers is not only unnecessary but can also distract from the primary focus of driving, which is ensuring safety for everyone on the road. By understanding when and how to use your horn appropriately, you contribute to a safer driving environment.
