The Mumbai traffic police took action against 5,445 vehicles and seized 584 motorcycle silencers that had been modified for enhanced sound during a special drive recently to curb air and noise pollution.

These seized silencers, which also cause air pollution due to emission of gases from the exhaust without filters, were crushed by a bulldozer in the presence Joint Commissioner of Police (Traffic) Praveen Padwal and other senior officials. There were over 700 vehicles wherein such silencers were installed. Fines were imposed by generating e-challans. While 20,946 vehicles were pulled up all through the year for not having pollution under control (PUC) certificates, a total of 5,866 cases were made just between November 7 and 15, an official stated.
