India, Jan. 9 -- If you own a 15-year-old BS3 petrol car in Delhi, you are no longer deciding based on preference or convenience. The law has already narrowed your choices. As per directions issued by the National Green Tribunal, petrol vehicles older than 15 years and diesel vehicles older than 10 years are not permitted to operate on Delhi roads. While the Supreme Court of India briefly paused enforcement in the past, the protection now applies only to vehicles that meet BS4 emission norms or higher.
