A Pollution Under Control (PUC) certificate is mandatory for every petrol, diesel, and CNG vehicle in India from 90 days after first registration, renewed every 6 months thereafter for older vehicles (some newer BS6 vehicles get an initial 1-year validity before shifting to the standard 6-month cycle). Getting one costs roughly ₹60-₹150 at any authorised testing centre and takes a few minutes. Driving without a valid PUC certificate can attract a fine, and penalties have risen since the 2019 Motor Vehicles (Amendment) Act, with amounts varying by state — always check your state's current fine schedule.

What a PUC certificate actually certifies
The PUC certificate confirms your vehicle's exhaust emissions — carbon monoxide (CO) and hydrocarbons (HC) for petrol/CNG vehicles, and smoke density for diesel vehicles — fall within limits prescribed under the Central Motor Vehicle Rules. It's a basic, quick test performed by inserting a probe into the exhaust while the engine idles, and most authorised centres complete it in under five minutes.
Validity timeline
A new vehicle is exempt from PUC testing for its first 90 days after registration, on the assumption that a brand-new vehicle's emissions are compliant. After that, PUC certificates typically need renewal every 6 months. Some BS6-compliant vehicles have been issued longer initial validity (in some cases up to a year) for their first certificate, after which the standard 6-month renewal cycle applies — the exact rule can vary by vehicle type and state, so check the validity date printed on your specific certificate rather than assuming.
How to get a PUC certificate
- Locate an authorised PUC testing centre — most fuel pumps in cities have one on-site, and independent authorised centres also exist
- Drive in with the vehicle running; the operator inserts a probe into the exhaust for a petrol/CNG check, or observes smoke density for diesel
- Pay the testing fee, typically ₹60-₹150 depending on fuel type and state
- Receive a printed certificate (and increasingly, a digital record linked to your vehicle registration number on the Vahan/parivahan system) showing the test result and validity date
Fines for driving without a valid PUC
Under Section 190(2) of the Motor Vehicles Act as amended in 2019, penalties for driving a vehicle that doesn't meet emission standards (which includes not carrying a valid PUC certificate) were significantly increased nationally, though individual states have applied and enforced the revised fine amounts at different paces and, in some cases, with local modifications. Repeat offences typically attract steeper fines than a first violation. Because the exact fine amount can change and differs by state, check your state transport department's current notified fine before assuming a specific figure.
A valid PUC certificate is also required for insurance renewal and to pass a vehicle fitness or RC renewal check — letting it lapse can create administrative hurdles beyond just a traffic fine. A suspiciously fast "pass" with no visible reading being taken is a sign of a fraudulent PUC centre — request to see the printed reading, not just the certificate.
Do electric vehicles need a PUC certificate?
No — since EVs produce no tailpipe emissions, they are exempt from PUC testing entirely. This is one of several small administrative and running-cost advantages EVs carry alongside lower fuel and maintenance costs.
What if your vehicle fails the PUC test?
- A failed test usually points to a poorly tuned engine, a clogged air filter, worn spark plugs (petrol) or a fuel injection/turbo issue (diesel)
- Get the issue diagnosed at a service centre rather than shopping around for a testing centre that will pass a non-compliant vehicle — this is both unsafe and illegal
- After the repair, most testing centres will re-test the same day once the issue is fixed
Checking your PUC status online
Many PUC readings are now uploaded to the central Vahan database linked to your vehicle registration number, meaning traffic enforcement can verify your PUC status digitally in some states even without you carrying a physical copy — but it's still safest to keep either a physical or digital copy on hand until this system is uniformly rolled out nationwide.
