As the Capital’s air quality plunges into the ‘very poor’ category, authorities are tightening curbs on polluting vehicles in order to combat rising smog levels.

The Commission for Air Quality Management in the National Capital Region and Adjoining Areas (CAQM) on Thursday directed agencies to strictly enforce a ban on the entry of commercial goods vehicles – except those that are CNG, LNG, electric, and compliant with BS-VI norms – into Delhi starting November 1. However, vehicles registered in Delhi will still be permitted to operate within the city.

“Considering the high pollution load from commercial vehicles and all associated ill effects of emissions from such vehicles entering Delhi, the commission directs a strict ban on commercial goods vehicles other than BS-VI, CNG, LNG, and EV from November 1,” it stated.

The Transport Department, traffic police, Delhi government, and NCR States have been instructed to ensure strict compliance with the directive.

The CAQM had earlier allowed BS-IV-compliant vehicles to enter the city till October 31 to ensure a smooth transition.
