Are BS-IV petrol cars allowed in Delhi under GRAP?
Short answer: The GRAP Schedule (Revision 29.09.2026) does not name BS-IV petrol cars in any stage's restrictions. Stage III (action #4) restricts only BS-III petrol and BS-IV diesel four-wheelers (LMVs).
- Stage I (#11): overaged petrol/diesel vehicles are prohibited as per NGT / Supreme Court orders — this depends on vehicle age, not BS norm.
- Stage IV (#5): states may impose extra measures such as odd-even; in that case, the respective state's order applies.
- Valid PUC is always required (Stage I #9).
Stage currently in force: I. Where the schedule is not explicit, we do not guess — check the latest CAQM / Delhi Transport Department order.
