Air quality continues to deteriorate in Delhi-NCR, with pollution levels not decreasing and reaching an AQI above 400 in some areas. Consequently, GRAP-3 restrictions have been implemented based on directives from the Central Government's Commission for Air Quality Management (CAQM). These measures prohibit the movement of vehicles that pollute the environment in the Delhi-NCR region.
Under GRAP-3, old and heavily polluting vehicles are banned from operating on the roads in Delhi, as well as in Noida, Greater Noida, Ghaziabad, Gurugram, and Faridabad.
According to GRAP-3 rules, gasoline vehicles of BS-3 standard and diesel vehicles of BS-4 standard are completely banned in Delhi. Similar restrictions apply to Noida and Greater Noida, where only certain types of vehicles are permitted to operate.
Some vehicle categories have been exempted from GRAP-3 restrictions. These include gasoline and diesel vehicles of BS-6 standard. Exemptions have also been granted to BS-4 gasoline vehicles, as well as BS-3 and BS-4 motorcycles and scooters. No ban has been imposed on transport running on compressed natural gas (CNG) or electric vehicles. Furthermore, privately modified vehicles for the use of persons with disabilities are also not subject to the ban.
Strict measures have been adopted under GRAP-3 regarding heavy and commercial transport. The entry of light and medium goods vehicles of BS-4 standard or lower from other states into Delhi has been prohibited. Additionally, further restrictions have been introduced for a number of BS-4 standard or lower diesel trucks, and some previously granted concessions for vehicles transporting essential goods have been revoked.
