In view of the deteriorating air quality level, the Air Quality Management Commission (CAQM) has implemented GRAP Phase 4 in Delhi NCR. As a result, BS3 and BS4 vehicles have been banned in the National Capital Region. The ban covers light motor vehicles (LMVs) as well as heavy motor vehicles. After this new ban, only BS-VI cars will be allowed in Delhi. This step has been taken in view of the ‘severe plus’ level of the Air Quality Index (AQI). To control the falling AQI numbers, the government first instituted GRAP Phase 3, but then increased the severity of the restrictions. Which vehicles are banned and which vehicles are allowed in Delhi NCR are explained in detail below.
With the implementation of GRAP Phase 4, the movement of diesel powered trucks is completely restricted in the national capital. Additionally, entry into Delhi will be restricted for cars with BS4 engines. Additionally, both Heavy Goods Vehicles (HGV) and Medium Goods Vehicles (MGV) will remain strictly prohibited.

Under the new restrictions of the Delhi government, diesel vehicles with BS6 engines will be allowed to enter the national capital. To ease transit, all vehicles powered by gasoline, electric and CNG will be allowed. In case of commercial vehicles, CNG trucks and electric trucks have also been allowed to be shifted to Delhi. Additionally, vehicles carrying MGVs and HGVs transport requirements as well as emergency services will be allowed to enter Delhi-boundaries. The NCRs apply to vehicles with the same BS-IV engine that utilize critical services.
The use of diesel generators is prohibited in GRAP Phase 4. However, the government has exempted essential services including hospitals, railroads, metro rail services, airports and inter-state bus terminals to ensure smooth operation of public transport. In addition, there are restrictions on important construction projects including highways, roads, flyovers and overbridges.
