As Delhi recorded an AQI of 493 on November 18, 2024, authorities have directed all schools to move classes online and have tightened restrictions on construction and vehicle movements. The level of PM2.5 in Delhi was 26 times higher than the WHO's limit, leading to the use of an anti-smog gun on a multi-purpose vehicle in an effort to reduce air pollution. With nine stations reporting an AQI of 500, the situation is even worse than the recorded 493.
