Honking is the sound made by a vehicle's horn, typically used to alert other drivers or pedestrians. It serves various purposes, such as signaling a warning, expressing frustration, or getting someone's attention. The sound can vary in pitch and duration depending on the vehicle and the driver's intent. In many places, honking is regulated by traffic laws to prevent excessive noise and ensure safety. While it can be a useful communication tool on the road, excessive honking can lead to disturbances and may be considered rude or aggressive. Understanding when and how to honk appropriately is important for maintaining road etiquette.
