For “Severe” AQI between 401 and 450, GRAP stage III is activated and when the AQI crosses 450 and air quality turns “severe plus”, the final Stage IV is implemented as countermeasures. Stage III measures were already being taken in Delhi and NCR where air quality is “severe plus” at the moment.

Following the implementation of GRAP Stage IV, all the construction and demolition activities, including public projects highways, roads, and pipeline work, have been banned in the national capital. Entry of trucks, except for those carrying essential supply items, into Delhi will remain banned under the GRAP Stage IV. However, LNG, LPG and electric trucks will be allowed.

Besides, light commercial vehicles (LCVs) registered outside Delhi, other than electrical vehicles, CNG, BS-VI diesel, will not be allowed to enter Delhi. Those carrying essential commodities or providing essential services will be exempted from the ban.
