Delhi will ban petrol and diesel vehicles registered outside the city from entering from November 1 if they do not meet BS-VI emission standards. CNG and electric vehicles are exempt from the restriction. The measure is part of the city's winter air pollution action plan under the Graded Response Action Plan (GRAP).

Other steps include a ban on construction and demolition activity, strict dust control at building sites and roads, and a crackdown on industrial emissions. The CAQM announced the measures as Delhi braces for its annual winter pollution crisis, which typically worsens due to stubble burning in neighbouring states and low wind speeds.
The GRAP system, first enforced in 2017, divides emergency measures into four stages based on the Air Quality Index. Stage IV, the most severe, includes a ban on trucks and a halt to construction. The new restriction on older non-Delhi vehicles targets the city's perpetual challenge: vehicular emissions constitute about 40 percent of Delhi's PM 2.5 load, according to a 2022 IIT Kanpur study. Winter months typically see the AQI exceed 400, triggering these measures. The Commission for Air Quality Management will enforce the plan starting November 1st. The first Stage IV alert of the season, if needed, will be announced by the CAQM based on the daily AQI reading from the Central Pollution Control Board.
