When is it illegal to use your car horn?

Using your car horn is primarily intended as a safety feature to alert others to your presence or to signal an immediate hazard. It is illegal to use your horn in situations where it could endanger or annoy other drivers because inappropriate or excessive honking can lead to confusion and increase the risk of accidents. It can also create a disruptive environment, particularly in residential areas or during quiet hours, making it important to use the horn judiciously and responsibly. This guideline helps ensure that honking serves its intended purpose of enhancing road safety rather than contributing to noise pollution or driver frustration.
