Traffic police have reintroduced the no-horn campaign in Kathmandu Valley to combat unnecessary honking.

Officers carrying placards with “no-horn” messages are stationed at various intersections, urging drivers to refrain from honking.

Deputy Superintendent of Police Rabin Karki, spokesperson for the Kathmandu Valley Traffic Police Office, said the campaign aims to curb noise pollution through stricter enforcement and public awareness.

Despite Kathmandu being declared a horn-free zone in April 2017, rampant horn use continues. Karki said the Vehicle and Transport Management Act prohibits honking in restricted areas, classifying it as a traffic violation.

Last fiscal year, 10,123 vehicles were fined for unnecessary honking. This year, 13,003 vehicles have already faced penalties. The awareness drive was relaunched on October 17.

Karki explained that while normal hearing can tolerate up to 60 decibels, 70 decibels is harmful. Noise pollution causes hearing loss, high blood pressure, heart disease, strokes, respiratory issues, and memory loss. Loud motorcycles and vehicles with modified silencers or pressure horns are major contributors.

The police are focusing on violators, with particular attention to the impact on pedestrians, especially children, the elderly, pregnant women, and those with health issues, Karki said.
