BS 3 petrol and BS 4 diesel cars were banned from roads in Delhi after GRAP Stage 3 measures were implemented on Friday (January 3).

NCR’s air quality revoked stage 3 restrictions under the Graded Response Action Plan on Sunday after air pollution levels eased. Stage 3, which was imposed on Friday, includes a ban on non-essential construction work.

GRAP 3 was reimposed after the air quality deteriorated. However, the city's 24-hour average air quality index (AQI) on Sunday stood at 339 at 4 pm.

The CAQM has withdrawn Stage-III restrictions under the GRAP in Delhi-NCR due to improving air quality indexes. Officials stated that Stage-I and Stage-II measures remain active. The AQI improvements are credited to favorable weather and higher wind speeds.

The Centre's air quality panel rolled back GRAP Stage 3 curbs in Delhi-NCR as pollution levels declined, though Stage 1 and 2 measures remain active to prevent further deterioration.

According to forecasts from the India Meteorological Department and the Indian Institute of Tropical Meteorology, the air quality is predicted to improve further -- from "severe" to "poor" -- due to favourable meteorological conditions.
