Aside from the headlamps, what is another requirement for motor vehicles as stated in traffic regulations?

The requirement for a motor vehicle to have at least one horn is crucial for safety and communication on the road. A horn serves as an important auditory signal that can alert other drivers and pedestrians of a vehicle's presence, especially in situations where visibility is limited or when approaching intersections. This regulation helps prevent accidents by enabling drivers to communicate their intentions or warn others of potential hazards.

While other features like seatbelts, reflectors, and functional windshield wipers are also important for vehicle safety and compliance with traffic regulations, the presence of a horn specifically addresses the need for auditory signaling in traffic scenarios. The horn is one of the basic safety devices in a vehicle, ensuring that drivers can warn others when circumstances require immediate attention.
