About this tool
Plan pollution certificate renewal dates and yearly cost by vehicle category using the 12-month and 6-month PUC validity rule.
This planner converts the date printed on your Pollution Under Control certificate into an expiry date, a booking date and a running cost, using the validity rule in Rule 115(7) of the Central Motor Vehicles Rules, 1989 — twelve months for the certificate issued with a newly registered vehicle, six months for every renewal after that. Pick your vehicle category and it also projects how many emission tests you will pay for over the next few years. Written for private owners and small fleets who want the renewal on the calendar before a traffic stop finds it.

Six months for most vehicles. Rule 115(7) of the Central Motor Vehicles Rules, 1989 gives the certificate issued for a newly registered vehicle a validity of one year from the date of first registration, and every certificate issued after that is valid for six months.
Up to ₹10,000 under section 190(2) of the Motor Vehicles Act, 1988 as amended in 2019. Several states also link the certificate to other services — for example, insurers have been directed to check for a valid PUC before renewing a policy — so a lapse can hold up more than a traffic stop.
Yes. Emission testing centres will test a vehicle at any time and issue a fresh certificate dated from the test, so testing a few days early costs you only the unused days on the old certificate. That is why this planner subtracts a booking buffer from the expiry date.
No certificate is issued. The vehicle has to be repaired — commonly a service, a new air filter, spark plugs or injector cleaning — and retested, and you pay the test fee again. Until it passes, the vehicle is being driven without a valid certificate, so plan the test with enough time for a repair.
