Delhi has banned BS-3 vehicles with immediate effect. The move is part of a mega plan to fight air pollution in the capital.

The government also plans to phase out BS-4 vehicles by 2030. The steps aim to cut vehicular emissions, a major source of pollution.

Delhi’s air quality worsens every winter. Old vehicles are among the biggest contributors to smog.

The plan includes stricter checks on polluting vehicles. More measures will be announced in phases.

Vehicle owners have been advised to check their vehicle’s emission norms. BS-3 vehicles are generally over 15 years old.

Environmental experts welcomed the move. They said strong enforcement will decide its success.

Delhi has tried vehicle bans before during smog episodes. The Graded Response Action Plan kicks in each winter. Experts say public transport must improve alongside bans. Many commuters depend on old vehicles for their livelihood. Enforcement teams will check vehicles on the roads.
