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

Using your vehicle's horn is primarily intended as a warning signal, especially in situations that may involve danger or the need to alert other drivers or pedestrians. Therefore, it is considered illegal to use your horn when it is not being employed for this purpose. This ensures that the horn remains an effective safety tool rather than a source of noise pollution or distraction.

In residential areas, using the horn unnecessarily can disturb the peace and may be regulated by local noise ordinances. While other vehicles' presence might impact the appropriateness of horn usage, the key factor remains that the horn must be a tool for caution rather than mere communication or frustration. Parking your vehicle does not inherently relate to horn usage legality, as horns should not be used simply to announce your arrival or presence in parking situations.
