GRAP-4 Reimposed in Delhi-NCR: What's Open, Closed, and Banned Amid 'Severe+' Air Quality

• The Commission for Air Quality Management (CAQM) reimposed GRAP-4 restrictions in Delhi-NCR due to AQI nearing 450 ('Severe+') after reaching 428.
• GRAP-4 bans entry of non-essential trucks into Delhi (except CNG, LNG, electric, BS-VI diesel) and plying of Delhi-registered BS-IV diesel heavy goods vehicles.
• All construction and demolition activities are banned, including linear public projects like highways and flyovers.
• Schools may shift to online mode for Classes 6-9 and 11; physical classes for Nursery to Class 5 are discontinued. Classes 10 and 12 are often exempted.
• Government and private offices are directed to operate with 50% staff on-site, with the rest working from home. Essential services remain operational.

Why It Matters: Delhi-NCR faces strict GRAP-4 curbs, including bans on construction and certain vehicles, as air quality deteriorates.
