What a PUC certificate is

A Pollution Under Control (PUC) certificate proves your vehicle's exhaust emissions meet CMVR standards. It is mandatory for all petrol, diesel and CNG vehicles under the Motor Vehicles Act — the fine for driving with an expired PUC is ₹10,000 (or up to 6 months imprisonment), and traffic police check it routinely at checkpoints. Electric vehicles are exempt because they have zero exhaust emissions.

PUC validity periods

  • Most vehicles — 6 months
  • New BS6 vehicles in their first year — 1 year, then reverting to 6 months

Always check the expiry date printed on your certificate. Exact fees vary by state and fuel type, but PUC remains one of the cheapest mandatory compliances at any authorised centre.

How to renew your PUC

  1. Find a testing centre — most petrol pumps have an in-house PUC station marked with a green board; you can also locate one via the VAHAN portal.
  2. Walk in — no appointment is needed and the process takes 5–10 minutes.
  3. Emission test — a probe measures CO, hydrocarbons and other pollutants against the standards for your vehicle's fuel type and age.
  4. Certificate on the spot — if you pass, the paper certificate and sticker are issued immediately and the data is uploaded to VAHAN instantly.

If your vehicle fails

Older vehicles frequently fail the emission test. A basic engine service — cleaning or replacing the air filter, cleaning fuel injectors, and tuning the engine — usually resolves it, after which you retest. CNG vehicles must be tested at CNG-specific centres, as not every petrol-pump station is equipped for them.

Check your PUC status

Enter your vehicle number on RC search to see PUC validity alongside registration details. A valid PUC is also required when buying a used car and for RC transfer. Understand the penalty side in the traffic challan guide, and find authorised centres through the RTO finder.

Frequently asked questions

How long is a PUC certificate valid?

For most vehicles it is valid for 6 months. New BS6-compliant vehicles in their first year get a certificate valid for 1 year, after which they revert to 6-month validity. Always check the expiry date printed on the certificate.

Where can I get a PUC certificate?

At any authorised emission testing centre — most petrol pumps have an in-house PUC station marked with a green board. You can also find nearby centres on the VAHAN portal (vahan.parivahan.gov.in) or your state transport app.

What is the fine for an expired PUC certificate?

Driving with an expired PUC carries a fine of ₹10,000 (or up to 6 months imprisonment) under the amended Motor Vehicles Act. Traffic police check PUC routinely at checkpoints, so keep it current.

Do electric vehicles need a PUC certificate?

No. Electric vehicles are exempt from the PUC requirement because they have zero exhaust emissions. This is a legal exemption under the Central Motor Vehicles Rules.

What happens if my vehicle fails the PUC test?

You cannot get the certificate until the issue is fixed. A basic engine service — cleaning or replacing the air filter, cleaning injectors, and tuning — usually resolves most failures, after which you retest.
