Delhi is once again tightening its grip on vehicle-related pollution with a major rule coming into effect from November 1, 2025. With air quality in the capital worsening every year, the government has now made it official — only BS6-compliant vehicles, CNG cars, and electric vehicles (EVs) will be allowed to enter the city. This move is part of the Air Pollution Mitigation Plan 2025, aiming to drastically reduce vehicular emissions and protect public health. Whether you’re a Delhi resident, a regular commuter, or someone planning to buy a new or used car, these rules directly affect your vehicle choices and travel plans. Let’s break down the full policy, how it’ll be implemented, what buyers should be careful about, and how brands are adapting.
Why This Matters: Delhi’s AQI is Getting Worse
If you live in Delhi or often travel there, you must have noticed how bad the air quality has become—especially during winters. The Air Quality Index (AQI) in Delhi and nearby states is constantly crossing the “severe” category. To tackle this, the Delhi government is tightening vehicle-related rules under its Air Pollution Mitigation Plan 2025. This is not just another rule—it’s a big change that will affect car owners, public transport, fuel stations, and even daily commuters.
What’s the New Rule Starting November 1, 2025?
From 1st November 2025, only BS6-compliant vehicles, electric vehicles (EVs), and CNG vehicles will be allowed to enter Delhi. This applies to all light, medium, and heavy vehicles. If your car or commercial vehicle doesn’t meet these criteria, it will be denied entry.
This proposal by the Delhi government has now been approved by the Supreme Court, making it a legally binding decision.
How Will It Be Enforced?
The government will install ANPR (Automatic Number Plate Recognition) cameras at all major entry points to Delhi. These smart cameras will instantly check the registration data of the vehicle, including:
- Vehicle age
- Fuel type
- Emission standard compliance (BS4, BS6, etc.)
If your vehicle is non-compliant, it will be stopped immediately and not allowed to enter.
This tech-backed approach ensures zero loopholes and strict implementation.
Fuel Ban for Old Cars: Even Petrol Pumps Will Enforce the Rule
This is where it gets even more serious.
ANPR cameras will also be installed at fuel stations. Vehicles not meeting the BS6, CNG, or EV standards will not be allowed to refuel. So, not only will such vehicles be stopped at borders, they’ll also be made non-functional inside the city.
This means even if you somehow manage to bring an old diesel/petrol car inside Delhi, you won’t be able to buy fuel for it.
Delhi Plans Artificial Rain & Dust Control Measures
Apart from vehicle regulations, the Delhi government is preparing to introduce artificial rain through cloud seeding technology, in collaboration with IIT Kanpur. This will help settle the dust and improve air quality during peak pollution months.
Additionally, mist sprayers will be installed across pollution hotspot areas to control dust levels on roads.
Why This Policy Matters to Car Buyers
If you are planning to buy a used car, petrol/diesel SUV, or bring your car to Delhi from another state — this policy directly affects you.
What You Should Keep in Mind:
- Buy only BS6-compliant cars if you plan to use them in Delhi post-Nov 2025.
- Consider switching to CNG or electric vehicles for long-term cost savings and pollution compliance.
- Avoid buying BS4 or older used cars even if they’re available at lower prices — they’ll be useless in Delhi soon.
- Check the registration year and fuel type before finalising any car purchase in NCR.

Conclusion: Time to Shift to Clean Mobility
