GRAP 4 in Delhi as AQI tops 400: What’s banned in 2025

Delhi invoked GRAP 4 after AQI crossed 400, triggering severe-plus curbs: ban on most construction and demolition, restrictions on BS-III petrol/BS-IV diesel vehicles, halt on truck entry except essential supplies, shutdown of polluting industries and diesel gensets, and advisories for schools and offices to switch to remote modes. Exemptions cover emergency, health, and public-transport services. Authorities will intensify enforcement measures.
