GRAP-4 Lifted in Delhi, But BS-4 Vehicles Still Restricted Under GRAP-3

• GRAP-4 restrictions have been lifted in Delhi due to improved air quality, but GRAP-3 rules remain in force.
• Under GRAP-3, BS-III petrol and BS-IV diesel four-wheelers are strictly restricted in Delhi and NCR districts.
• GRAP-3 imposes a complete ban on most construction/demolition activities, stone crushers, and mining across NCR.
• Delhi-registered diesel medium goods vehicles (BS-IV or below) and non-Delhi registered BS-IV diesel goods vehicles are banned from entry.
• GRAP-3 mandates hybrid mode for classes up to 5th and suggests work from home for government and private offices.

Why It Matters: Despite GRAP-4 removal, strict GRAP-3 rules, including BS-4 vehicle restrictions, persist in Delhi.
