Vehicles with multi-tone horns and sirens are found to be violating noise pollution rules

The National Green Tribunal (NGT) has directed the Union government to notify standards for sirens and multi-tone horns used by vehicles including those of Government, police or ambulance within three months. The directions were issued by principal bench of Justice A S Naidu and G K Pandey who felt an urgent need to have source specific noise standards, as there were no standards specified by the Union government with regard to use of horns and sirens in ambulances, government and police vehicles.
