Where is it inappropriate to use your horn?

Using your horn in built-up areas is generally considered inappropriate, primarily due to the potential for noise pollution and the potential to startle pedestrians and other road users. Built-up areas often include residential neighborhoods and places where people congregate, such as shopping districts or schools. In these environments, excessive horn use can disturb the peace and disrupt the daily activities of residents and pedestrians.

The social norms and traffic regulations in such areas encourage more courteous communication, often relying on visual signals and the awareness of one's surroundings rather than auditory signals like horns. Additionally, many built-up areas have specific laws that restrict horn use to emergencies only, reinforcing the expectation that drivers should be mindful of their surroundings and considerate of those who might be affected by noise.
