Vehicle-related curbs currently escalate along with the GRAP stage. This page is for general awareness — always check official CAQM / Delhi Traffic Police notifications before travel.
Restriction check is based on the live, currently active GRAP stage — not a stage you pick manually.
This tool estimates the BS (Bharat Stage) emission standard from the registration year, checks the requested age rules (10+ years diesel / over 15 years petrol), and then applies the current live GRAP stage rules shown above. It covers private four-wheelers only — trucks and other goods vehicles follow separate rules (see the table below). Always confirm the actual GRAP stage in force today from CAQM before making decisions.
| Stage | AQI Range | Vehicle Restrictions |
|---|---|---|
| Stage I | 201–300 (Poor) | No specific vehicle ban. Strict action against visibly polluting vehicles and idling at traffic signals is enforced. |
| Stage II | 301–400 (Very Poor) | Parking fees hiked to discourage private vehicle use; increased CNG/electric bus and metro frequency to shift commuters away from private cars. |
| Stage III | 401–450 (Severe) | BS-III petrol and BS-IV diesel four-wheelers banned from plying in Delhi-NCR (except essential services). Non-electric / non-CNG / BS-VI diesel medium goods vehicles restricted, barring essential goods carriers. |
| Stage IV | 450+ (Severe+) | Entry of trucks into Delhi stopped, barring those carrying essential commodities or providing essential services. Diesel-run medium and heavy goods vehicles barred, except essential-goods carriers. State governments may impose additional local curbs including odd-even, at their discretion. |
These restrictions change frequently based on live AQI. This page is informational and not a substitute for the official CAQM order in force on any given day.
