New Delhi: As Delhi’s air quality worsens, the Delhi government has introduced emergency traffic curbs under the Graded Response Action Plan (GRAP).
From Thursday, only BS6-compliant vehicles registered outside Delhi will be allowed to enter the city when GRAP Stage III or IV is in force, a move that could keep nearly 12 lakh vehicles off Delhi’s roads during peak pollution days.
Why Are These Curbs Being Implemented Now?
During winter, Delhi’s weather traps pollutants close to the ground, causing air quality to drop. Vehicle emissions contribute to about 40% of pollution in heavy traffic areas.
To reduce pollution and health risks, Delhi is restricting the entry of older, more polluting vehicles during times of severe air quality.
Which Vehicles Can Enter Delhi During High Pollution?
Under Grap Stage 3 and 4, only BS6-compliant vehicles from outside Delhi can enter the city.
BS6 is a stricter emission standard, and these vehicles are cleaner than older models.
Allowed: BS6 vehicles registered outside Delhi and any BS6 vehicles within Delhi that have a valid Pollution Under Control (PUC) certificate.
Barred: Non-BS6 vehicles registered outside Delhi and older vehicles with higher emissions.
Do You Need a PUC Certificate?
Yes. The PUC certificate is required across all GRAP stages. If your vehicle doesn’t have a valid certificate, you could be denied fuel at petrol stations in Delhi, regardless of pollution levels.
How Are These Rules Enforced?
Delhi uses Automatic Number Plate Recognition (ANPR) cameras at key locations, including petrol stations and entry points.
These cameras will automatically check for vehicles without a valid PUC certificate.
How Many Vehicles Will Be Affected?
Around 2 lakh vehicles registered outside Delhi could be impacted by these restrictions during severe pollution days.
How Long Will These Restrictions Last?
These curbs will remain in place for as long as the GRAP Stage 3 and 4 is active. Authorities will review air quality daily and adjust the rules based on pollution levels.
What Should Drivers Do to Avoid Fines?
- Check the GRAP stages before travelling
- Make sure your vehicle is BS6-compliant.
- Carry a valid PUC certificate.
- Plan your routes based on which areas have restrictions.
