Overview
- Non-Delhi vehicles below BS-VI are barred from entering the capital except for essential services, while Delhi-registered BS4 petrol cars may operate only with a valid PUCC and out-of-state BS4 petrol vehicles are prohibited.
- Delhi enforces the year-round “no PUCC, no fuel” rule at petrol pumps to ensure vehicles meet emission norms.
- Construction and demolition are halted except for essential public projects, and brick kilns, stone crushers, hot-mix plants and other high-emission units remain shut.
- The Directorate of Education directs Classes up to 9 and Class 11 to shift to hybrid mode, with Classes 10 and 12 allowed to continue in-person.
- Enforcement intensifies with ANPR cameras and on-ground checks, with fines up to Rs 20,000 and potential impoundment, as dense fog also delays flights and slows road and rail traffic.
