If GRAP-4 kicks in, here’s what will be restricted News24 –

By Correspondent On Nov 18, 2025

Delhi and neighbouring Noida are currently enveloped in a thick, toxic smog, making the air extremely difficult to breathe, especially early in the morning. The situation has raised concerns as air pollution levels in the region remain dangerously high, despite the government implementing GRAP Stage 3 measures to control emissions.

The Commission for Air Quality Management (CAQM) has clarified that reports of GRAP-4 being implemented in Delhi are false. A notice issued by the commission urges residents not to believe any rumours or unverified news regarding GRAP-4. Currently, only GRAP Stage 3 rules are in effect and the commission advises people to rely solely on official updates.

When GRAP-4 could be triggered

GRAP-4 measures are triggered when Delhi’s Air Quality Index (AQI) crosses 451, entering the ‘severe’ pollution category. On 18 November 2025, the AQI in Delhi was recorded at 341, classified as ‘very poor’, with some areas even exceeding 400. The city is already in the red zone and GRAP Stage 3 measures remain active. Schools in Delhi are operating in hybrid mode, following the current pollution control rules. The Central Pollution Control Board (CPCB) continues to monitor the situation closely.

What GRAP-4 would mean

If GRAP-4 is enforced, stricter restrictions would come into effect. Only CNG, LNG, BS-IV diesel and electric vehicles would be allowed, while other vehicles and trucks would be barred from entering Delhi. Public and government construction activities would be suspended and 50% of employees would be required to work from home to reduce road congestion. The decision on whether schools would be closed under GRAP-4 would be taken jointly by CAQM and the Delhi government, as it depends on pollution levels and safety considerations.

For now, Delhi residents are urged to follow CAQM advisories, avoid unnecessary outdoor travel and take precautions, especially children, the elderly and those with respiratory issues, until air quality improves.
