Delhi BS-4 Vehicles: Allowed Under GRAP-3, Avoid Rs 20,000 Challan

• BS-4 petrol vehicles are currently permitted in Delhi under GRAP-3, irrespective of their registration state.
• Entry of BS-3 petrol and diesel vehicles remains prohibited in Delhi, with a challan up to Rs 20,000.
• A valid PUC certificate is mandatory for all vehicles; driving without one incurs a challan up to Rs 10,000.
• GRAP-4 restrictions were lifted on December 24 due to slight pollution improvement, with GRAP-3 now in effect.
• Confusion regarding BS-4 vehicle entry persists due to frequent changes in Delhi's pollution control rules.

Why It Matters: BS-4 petrol vehicles are allowed in Delhi under GRAP-3, but BS-3 vehicles face heavy fines.
