Delhi activates winter pollution curbs from Nov 1: bans non-BS-VI out-of-state vehicles, enforces WFH, construction limits, higher parking, ANPR/AI checks. Delhi govt activates its special winter pollution restrictions Sunday, rolling out a broader seasonal framework that goes beyond the emergency measures imposed under the Graded Response Action. The curtailments will affect office-goers, commuters, vehicle owners, and construction activities. The curbs are imposed to reduce vehicular emissions, control dust pollution and improve air.
