BS III, IV vehicles allowed to ply in Delhi as Stage-III of GRAP rolled back

BS III petrol and BS IV diesel vehicles will be allowed to ply in Delhi as the Centre's pollution control panel on Tuesday ordered the removal of GRAP Stage-III curbs in Delhi-NCR due to improvement in air quality. However, all restrictions under Stage-I and Stage-II will remain imposed to ensure that the air quality doesn't slip into the 'severe' category.
