The Delhi non-BS6 vehicle ban starts in less than a week. From November 1, 2026 to January 31, 2027, vehicles registered outside Delhi that do not meet BS6 emission norms will not be allowed to enter the city. Chief Minister Rekha Gupta announced the rule on October 20 as part of Delhi’s Winter Action Plan.
Electric vehicles, CNG vehicles and essential services are exempt. Vehicles registered in Delhi are not covered by this particular rule. The wider plan also brings a “No PUC, No Fuel” rule at fuel stations, doubled parking fees at municipal lots and 50 percent work from home for offices.
What has not been announced yet is exactly how the ban will be enforced at the border. That gap matters, so below we separate what is confirmed from what is still unclear, and explain what you should do if you drive or ride into Delhi from Gurugram, Noida, Ghaziabad, Faridabad or further away.
What exactly does the Delhi non-BS6 vehicle ban say?
The rule is short. Non-Delhi vehicles below BS6 norms will not be allowed to enter Delhi between November 1 and January 31. The Winter Action Plan itself runs longer, until February 28, 2027.
The government’s wording does not single out cars. It refers to vehicles registered outside Delhi, which means older two-wheelers from neighbouring states also appear to fall within its scope. Several reports have read it the same way. Until a formal notification spells out vehicle categories, assume your BS4 motorcycle or scooter is included.
This is also wider than last year’s restriction. In 2025, the Commission for Air Quality Management (CAQM) targeted non-BS6 commercial goods vehicles registered outside Delhi. A temporary relaxation for some BS4 goods vehicles carrying essential supplies ran until October 31, 2026. That relaxation now ends, and private cars and bikes are being added on top.
Who is exempt?
Three groups are outside the ban, based on the government’s announcement:
- Electric vehicles registered anywhere
- CNG vehicles registered anywhere
- Essential and emergency services, such as ambulances and fire services
BS6 vehicles registered outside Delhi are not affected, because they already meet the standard. Delhi-registered vehicles are also not covered by this entry rule, although other rules still apply to them, including the end-of-life vehicle restrictions and GRAP curbs.
One point to watch is factory-fitted versus retrofitted CNG. The announcement simply says CNG vehicles. It does not say whether an older petrol car with an aftermarket CNG kit will be treated the same way. If that describes your car, carry the RC showing the CNG endorsement and do not rely on it until the enforcement notice clarifies this.
How do I check if my vehicle is BS6?
BS6 norms became mandatory for new vehicles sold in India from April 1, 2020. So if your car or bike was bought new after that date, it is almost certainly BS6. If it was bought before April 2020, it is most likely BS4 or older.
Do not rely on the purchase year alone, especially around early 2020, when some BS4 stock was still being cleared. The safer way is to check the emission norm listed on your registration certificate, or the vehicle record in the official mParivahan app. If your PUC certificate lists the norm, that is a useful second check.
How does this fit with GRAP and other pollution rules?
Delhi’s winter now has several overlapping rules. The Winter Action Plan is separate from the Graded Response Action Plan (GRAP), which CAQM triggers according to air quality. GRAP Stage 1 is already in force.5:26 PM
| Rule | Who it affects | When |
|---|---|---|
| Winter Action Plan entry ban | Non-BS6 vehicles registered outside Delhi (EV, CNG, essential services exempt) | Nov 1, 2026 to Jan 31, 2027 |
| No PUC, No Fuel | Any vehicle without a valid PUC, at Delhi fuel stations | From Nov 1, under the Winter Action Plan |
| Doubled parking fees | Authorised municipal parking (DMRC lots excluded) | Nov 1, 2026 to Feb 28, 2027 |
| GRAP Stage 3 | BS3 petrol and BS4 diesel four-wheelers in Delhi and five NCR districts | Only when AQI is forecast at 401-450 |
| GRAP Stage 4 | Truck entry into Delhi, except LNG, CNG, electric and BS6 diesel | Only when AQI is forecast above 450 |
5:26 PM
The GRAP Stage 3 car curbs apply in Delhi and in the high-density districts of Gurugram, Faridabad, Sonipat, Ghaziabad and Gautam Buddh Nagar. Sonipat was added in CAQM’s September revision. That means a BS4 diesel car can face limits even on the NCR side, on bad air days.
What does No PUC, No Fuel mean in practice?
Fuel stations across Delhi will refuse petrol, diesel, CNG and LPG to vehicles without a valid Pollution Under Control certificate. Automatic Number Plate Recognition (ANPR) cameras at 500 fuel stations will check compliance.
This rule applies to everyone, including Delhi-registered BS6 cars. A lapsed PUC is a common oversight, so check its validity date now.
Is enforcement at the border confirmed?
Not in full detail. Reports from October 23 say enforcement details are yet to be announced. What we do know from a Delhi Traffic Police coordination meeting is that display boards will be put up at border points to warn motorists. Joint enforcement teams may also be set up, and agencies will coordinate with neighbouring states.
We have not seen an official figure for penalties specific to this entry ban, so we are not quoting one. Expect to be turned back at a minimum.
What should NCR commuters do now?
Your options depend on your vehicle:
- BS4 petrol or diesel car from outside Delhi: plan an alternative for three months. Metro plus last-mile options, carpooling with a BS6 owner, or working from home where your employer allows it.
- BS4 two-wheeler from outside Delhi: treat it as included. The Metro and electric buses are the government’s preferred alternative.
- CNG vehicle: you should be exempt, but carry an RC showing the CNG fuel type. CNG options are growing too, such as the Mahindra XUV 3XO CNG compact SUV.
- EV owner: you are exempt from the entry ban, and the No PUC rule does not apply.
If you were already thinking of replacing an old bike, this winter is a sensible trigger. A family electric scooter like the Simple Energy Wave with its large storage and range claims avoids every one of these restrictions. Do not rush a car purchase purely for three months of rules, though. Work out the cost of alternatives first.
CarBike Insight Analysis
This is the most direct winter curb on private vehicles that Delhi has announced in years. It is also blunt. Registration location, not actual emissions, decides who gets in, so a well-maintained BS4 car from Gurugram is stopped while a poorly maintained BS4 car registered in Delhi is not caught by this rule.
That said, the direction is clear. Each winter, the list of vehicles that can move freely in Delhi gets shorter, and BS6, CNG and electric vehicles are the ones that stay on it. For anyone buying a car or bike in the NCR, that is now a practical buying factor, not just an environmental one.
Our advice: check your RC today, renew your PUC, and do not assume older rules from 2025 still apply. If you are switching to an EV because of this, look at charging access first, because reliable public charging in India still varies a lot by location. And watch for the formal enforcement notice before November 1, which should settle the open questions on two-wheelers and retrofitted CNG.
