Is a driver allowed to sound the horn while driving in a built-up area at night?

A driver is allowed to sound the horn while driving in a built-up area at night, but this is restricted to emergencies or specific situations for safety reasons. The use of the horn is generally intended to warn others and prevent accidents; hence, it should be used judiciously, especially during night hours when noise can be more disruptive. In non-emergency scenarios, using the horn could be considered excessive and could disturb the peace in residential areas.

In this context, the regulation ensures that drivers can alert others of potential dangers without creating unnecessary noise pollution, which could occur if the horn were used freely. Hence, the correct answer acknowledges the necessity of using the horn responsibly while still allowing for its use in urgent situations.
