A pollution certificate in Delhi (PUCC) is issued after an authorised
emission testing centre checks your vehicle's exhaust and confirms it meets prescribed limits. It costs Rs. 80–140 depending on
vehicle type, and stays valid for just 3 months for older vehicles or 12 months for BS-IV/BS-VI compliant vehicles, shorter than most
other states.
Driving without one attracts a fine of up to Rs. 10,000 and since
December 2025, Delhi petrol pumps can refuse to fuel any vehicle without a valid PUC showing on VAHAN, a rule the Delhi government made
a permanent, year-round policy from April 2026.
A PUC certificate is one of those documents most vehicle owners in Delhi only think about when a traffic stop, a fuel pump attendant, or an insurance renewal forces the issue.
Delhi runs the strictest PUC regime in the country — the shortest validity window, the steepest fine, and since 2026, a rule that can stop you from filling fuel at all if your certificate has lapsed.
This guide covers exactly how to get a pollution certificate in Delhi, how to check or download an existing one online, what it costs, how long it lasts, and the rules that catch out even careful vehicle owners — from the No PUC No Fuel policy to the GRAP-linked enforcement drives each winter.

What Is a Pollution
Certificate (PUC) in Delhi?
A Pollution Under Control Certificate, commonly called a PUC certificate
or PUCC, is an official document confirming that your vehicle's exhaust emissions fall within the limits set by the government. In
Delhi, it's issued through a network of authorised emission testing centres regulated by the Transport Department, Government of NCT of
Delhi.
Every petrol, diesel and CNG vehicle registered in Delhi needs one,
two-wheelers, cars, autos and commercial vehicles alike. An operator tests your exhaust with a gas analyser or smoke meter and issues the
certificate on the spot if your vehicle passes.
Who Needs a PUC Certificate in Delhi?
Every registered motor vehicle running on petrol, diesel or CNG needs a
valid PUCC, with one exception: brand-new vehicles are typically exempt for their first year from the date of registration, since their
emission systems are assumed compliant fresh from the factory.
Once that first year is up, you're required to get your vehicle tested
and carry a valid certificate at all times. Delhi Traffic Police issued over 2.7 lakh challans for PUC violations between January and
October 2024 alone (the highest in three years), proof that the checks are frequent, not occasional.
How to Get a Pollution Certificate in Delhi (Offline)
There's no way to get a fresh PUC certificate purely online in Delhi, the
emission test itself has to happen in person. Here's the process:
- Locate an authorised PUC testing centre near you, Delhi has around 966 emission testing centres, most attached to petrol pumps.
- Drive to the centre with your vehicle running normally (avoid testing right after a cold start, as readings can be less favourable).
- The operator tests your exhaust, a gas analyser probe for petrol/CNG vehicles, a smoke meter for diesel vehicles.
- If your readings are within the prescribed limit, pay the applicable fee (see the fee table below).
- Collect your printed PUC certificate, it now syncs to your DigiLocker/mParivahan record via a QR code, so check that it shows the official fee charged.
Pro Tip
Get your vehicle serviced before a PUC test if it's due for one. A poorly tuned engine or a clogged air filter is the most common reason
for failing an emission test.
Types
of Emission Tests Conducted for Your Vehicle in Delhi
The actual test at the centre isn't the same for every vehicle, it
depends on your fuel type, since petrol/CNG engines and diesel engines release different pollutants.
Idle test, for petrol, CNG & LPG vehicles
The operator inserts a probe into your exhaust pipe while the engine idles, without pressing the accelerator. The analyser measures
carbon monoxide (CO, as a percentage by volume) and unburnt hydrocarbons (HC, in parts per million). Only one reading is taken and used
as the final result.
Smoke meter (free acceleration) test, for diesel vehicles
Since diesel engines emit smoke rather than CO/HC in significant quantities, the operator revs the engine from idle to maximum speed and
back, and a smoke meter measures the opacity of the exhaust smoke. A higher opacity reading indicates higher pollutant levels. This is
repeated across a few cycles, and the average is taken as the final reading.
Either way, the process takes 10–15 minutes, and the centre reports
the result straight to the VAHAN/Parivahan system, if your vehicle fails, that failure is also logged against your registration
number.
How to Check or Download Your PUC Certificate Online
You can't renew your PUC online, but you can check its status or download
an existing certificate through the government's Parivahan portal, or via the mParivahan app. This is useful if you've lost your
physical copy or need to confirm your expiry date before a fuel stop or a long drive.
- Visit the official Parivahan PUC portal (puc.parivahan.gov.in or vahan.parivahan.gov.in/puc/).
- Select the "PUC Certificate" tab under Online Services.
- Enter your vehicle's registration number and the last five characters of your chassis number.
- Submit the details to view your current PUCC status, validity date and download a copy if one is on file.
PUC Certificate Validity in Delhi
Delhi's validity rules are noticeably shorter than most of the country.
How long your certificate stays valid depends on your vehicle's age and emission standard:
Vehicle Category |
Status |
Validity Period |
New vehicle |
First year on the road |
Not required for 1 year from registration |
BS-IV / BS-VI compliant vehicles |
On renewal |
12 months |
All other vehicles (older, non-BS-IV/VI) |
On renewal |
3 months |
Most other states allow 6 months' validity for older vehicles, Delhi's
3-month cycle means owners of older vehicles need to renew roughly four times a year, not twice. Since renewal cycles can vary slightly
by vehicle, the safest habit is to check your exact expiry date on Parivahan rather than assuming based on your last certificate.
PUC Certificate Fees in Delhi
Testing fees are fixed by the Delhi Transport Department, and were
revised in July 2024 for the first time in 13 years, every authorised centre is required to follow the current rates:
Vehicle Type |
Testing Fee |
Two/three-wheelers (petrol, CNG, LPG) |
Rs. 80 |
Four-wheelers and above (petrol, CNG, LPG) |
Rs. 110 |
Diesel vehicles |
Rs. 140 |
Always collect the printed certificate showing the fee charged, this is
the easiest way to confirm you haven't been overcharged at a testing centre.
Fine for Driving Without a Valid PUC Certificate in Delhi
Warning
Driving without a valid PUC certificate in Delhi can attract a fine of up to Rs. 10,000 under Section 190(2) of the Motor Vehicles Act,
along with possible imprisonment of up to 6 months and suspension of your driving licence for 3 months. Delhi Traffic Police issued over
2.7 lakh PUC challans in a single year, with AI-enabled cameras now flagging violations automatically.
This is significantly steeper than the fine in several other states, which
is one reason Delhi vehicle owners can't afford to treat PUC renewal as optional, the Rs. 80–140 testing fee is a fraction of what
a single missed renewal can cost.
The "No PUC, No Fuel" Rule in Delhi (2026)
Important to Know
Delhi's "No PUC, No Fuel" rule was first strictly enforced from 18 December 2025, when the Delhi government deployed 126 checkpoints, 580
police personnel and ANPR (Automatic Number Plate Recognition) cameras at petrol pumps to block fuel sales to vehicles without a valid
PUCC. In April 2026, under the Air Pollution Mitigation Action Plan 2026, Delhi Chief Minister Rekha Gupta announced the rule would be
enforced year-round rather than only during winter pollution spikes. This makes it a standing policy, not a seasonal one.
Within days of the December 2025 enforcement drive, Delhi's Environment
Minister said over two lakh PUC certificates had been issued as vehicle owners rushed to comply, a sign of how quickly the rule changed
behaviour at the pump.
This is a meaningful shift from how PUC enforcement used to work. Earlier,
an expired certificate mainly risked a challan if you were stopped. Now it can stop you from fuelling your vehicle at all, since pump
attendants check your registration number against the VAHAN database before fuelling. If your last PUC test wasn't synced correctly,
it's worth checking your status on Parivahan before you're standing at the pump with an empty tank.
PUC Rules Get Stricter During Delhi's Winter Pollution Season
Delhi's air quality typically worsens sharply between October and
January, and PUC enforcement tightens along with it. During GRAP (Graded Response Action Plan) Stage 2–4 periods, when AQI crosses
set thresholds, traffic police and the Transport Department run intensified checks at high-traffic junctions.
Special drives have resulted in over 47,000 PUC challans being issued in a
single three-week window at locations like ITO Chowk, Peeragarhi, Ashram Chowk, Anand Vihar and Mehrauli. If your PUC is due for
renewal, getting it done before October rather than during a GRAP-driven crackdown avoids both the fine risk and the longer queues at
testing centres.
Can Old Diesel and Petrol Vehicles Get a PUC in Delhi?
Not always. Delhi enforces an End-of-Life (EOL) vehicle ban that a PUC
certificate cannot override: diesel vehicles older than 10 years and petrol vehicles older than 15 years are barred from being driven,
refuelled or re-registered in Delhi-NCR, regardless of how clean their emissions test.
Testing centres cannot issue a fresh PUC to a vehicle that has crossed
this age limit, the vehicle is expected to be scrapped or relocated outside Delhi-NCR with a valid No Objection Certificate (NOC) from
the registering RTO. This catches out several long-term owners who assume a passing emission test is enough on its own.
PUC Certificate and Your Motor Insurance Renewal
Important to Know
Under an IRDAI circular first issued on 6 July 2018 (reiterated on 20 August 2020), general insurance companies must verify that your
Pollution Under Control certificate is valid before renewing your motor insurance policy. This applies only to renewal, the 2020
circular clarifies that an insurer cannot reject an accident claim solely because your PUCC had expired, so an existing policy stays
valid even if your PUC lapses mid-term. In practice, this means an expired PUCC can now hold up your car or bike insurance renewal in
Delhi too, not just attract a traffic fine or block a fuel top-up.
It's a good habit to renew your PUC certificate a few weeks before your
motor insurance policy is due, so one expired document doesn't end up delaying the other. If your insurance renewal is approaching,
checking your PUCC status on Parivahan first can save you a last-minute scramble.
Where to Get Your Vehicle Tested in Delhi
Delhi has authorised PUC testing centres across the city, with roughly
966 centres including those attached to petrol pumps in areas like Dwarka, Rohini, South Delhi and Mayur Vihar. Since individual centres
open, close and change contact numbers fairly often, the most reliable way to find one near you is through the official channels below
rather than a fixed list:

What to Do If Your Vehicle Fails the PUC Test
A failed emission test almost always points to a maintenance issue rather
than a paperwork one. Common causes include a dirty air filter, worn spark plugs, incorrect fuel-air mixture, or a vehicle that hasn't
been serviced in a while.
- Get your vehicle serviced at an authorised workshop before retesting.
- Ask the mechanic to specifically check the exhaust and carburettor or fuel injection system.
- Retest at the same or a different authorised centre once the issue is fixed, there's no cooling-off period.
- If your vehicle repeatedly fails, get a full emission-system diagnostic rather than retesting blindly.
Common Mistakes Delhi Vehicle Owners Make with PUC Certificates
- Assuming Delhi's validity is 6 months like most states
Older vehicles here need renewal every 3 months.
- Not realising the certificate can't be renewed online
It can only be checked or downloaded if already issued.
- Getting caught out at the pump by the No PUC No Fuel rule
Because a renewed PUC hadn't synced to VAHAN yet.
- Assuming a passing emission test guarantees renewal
It doesn't override Delhi's End-of-Life vehicle age limits.
- Letting the PUCC lapse right before an insurance renewal date
Which can delay the policy renewal too.
Final Word
A pollution certificate is one of the cheapest and quickest
documents to keep current, and in Delhi the stakes for skipping it are unusually high, a steep fine, a possible refusal at the fuel
pump, and a delayed insurance renewal, all from one expired slip. Check your PUCC status on Parivahan today, and if it's close to
expiry, get it renewed before the next GRAP-driven enforcement drive catches you out.

FAQs
Yes, every petrol, diesel and CNG vehicle registered in Delhi needs a valid PUC certificate once it's more than a year old. This applies to two-wheelers, cars, autos and commercial vehicles alike. New vehicles are typically exempt for their first year from the date of registration.
No, renewal requires a physical emission test at an authorised centre. You can only check the status of an existing certificate or download a copy online through the Parivahan portal — the actual test can't be done remotely.
The fine is up to ₹10,000 under Section 190(2) of the Motor Vehicles Act, along with possible imprisonment of up to 6 months and a 3-month driving licence suspension. This is higher than the fine enforced in several other states.
New vehicles don't need one for their first year on the road. BS-IV and BS-VI compliant vehicles get 12 months' validity on renewal, while all other vehicles are valid for just 3 months — shorter than the 6-month cycle common in most other states.
Reactivated from April 2026, this rule bars Delhi petrol pumps from fuelling any vehicle whose PUC certificate isn't showing as valid on the VAHAN database. It's checked at the pump itself, so an expired or unsynced certificate can stop you from refuelling, not just risk a challan.
Not if it's older than 10 years. Delhi's End-of-Life vehicle rules bar diesel vehicles over 10 years and petrol vehicles over 15 years from being tested, refuelled or driven in Delhi-NCR — the vehicle must be scrapped or relocated with an NOC.
Yes. Following an IRDAI circular, general insurance companies now verify PUCC validity before renewing motor insurance policies. An expired pollution certificate can delay your car or bike insurance renewal, so it's worth renewing both around the same time.
Testing fees are ₹80 for two/three-wheelers, ₹110 for four-wheelers running on petrol, CNG or LPG, and ₹140 for diesel vehicles, as revised by the Delhi Transport Department in July 2024. Always collect the printed certificate showing the fee charged.
