Delhi NCR faces severe air pollution every winter, and when pollution levels cross critical limits, authorities enforce GRAP Stage 4, the strictest phase of the Graded Response Action Plan (GRAP).
During GRAP 4, vehicle movement restrictions become far more aggressive than regular age-based bans, leading to confusion among car owners especially around petrol vs diesel vehicles.
If you own a Hyundai or plan to drive in Delhi NCR during high-pollution periods, understanding GRAP Stage 4 vehicle ban rules is crucial to avoid fines, vehicle seizure, or forced parking.
Expert Note:
This article is reviewed by automotive professionals at DS Automobiles Authorized Hyundai Service Center, Noida, ensuring real-world accuracy and compliance-focused guidance.
What Is GRAP (Graded Response Action Plan)?
GRAP is an emergency pollution-control framework implemented to tackle rising air pollution levels in Delhi NCR. It works in four stages, with restrictions increasing as air quality worsens.
GRAP measures are activated based on Air Quality Index (AQI) levels and apply across Delhi NCR, including Noida, Ghaziabad, Gurugram, and Faridabad.
GRAP Stages 1, 2 & 3: A Quick Overview
Before the strict GRAP Stage 4 is enforced, authorities gradually tighten controls through earlier stages.
GRAP Stage 1 (Poor Air Quality)
- Triggered when AQI reaches Poor levels
- Focus on awareness and preventive measures
- Minimal impact on private vehicles
- Increased pollution monitoring
Most private vehicles remain unaffected.
GRAP Stage 2 (Very Poor Air Quality)
- Activated when AQI worsens to Very Poor
- Increased scrutiny of visibly polluting vehicles
- Higher parking fees to discourage private vehicle use
- Restrictions on diesel generators
Older vehicles may face checks, but bans are limited.
GRAP Stage 3 (Severe Air Quality)
- Construction activities are partially banned
- BS3 petrol and BS4 diesel vehicles may face restrictions
- Non-essential diesel vehicles are discouraged
- Entry of trucks may be limited
This stage acts as a warning before GRAP 4.
What Is GRAP Stage 4?
GRAP Stage 4 is activated when AQI crosses “Severe” or “Severe Plus” levels (450+).
GRAP Stage 4 is enforced when:
- Air quality becomes extremely hazardous
- Health risks rise sharply for all age groups
- Immediate reduction in vehicular and industrial emissions is required
This stage introduces temporary but very strict vehicle bans, regardless of vehicle condition or maintenance history.
Why Are Vehicle Bans Enforced During GRAP 4?
Vehicular emissions are one of the fastest controllable pollution sources in Delhi NCR.
During GRAP 4:
- Traffic emissions are reduced immediately
- High-polluting vehicles are restricted
- Only essential and cleaner vehicles are allowed
Authorities prioritize public health and emergency pollution control over daily convenience.

“My car is BS6, so I’m safe”
Not always BS6 diesel vehicles can still be restricted.
