PUC Certificate: Pollution Under Control
In this guide
Step-by-step Process
What is PUC and Why It is Mandatory
Pollution Under Control (PUC) is a certificate that your vehicle's emissions are within permissible limits. Mandatory under Motor Vehicles Act for all vehicles. Checked at: Traffic police checks, vehicle fitness inspection, RC renewal, entry to some zones (odd-even, green zones). Fine for no valid PUC: ₹1,000 (first time), ₹2,000 (repeat).
PUC Validity Period
New vehicles: PUC valid for 1 year from date of first registration. After first year: PUC certificate valid for 6 months (petrol/CNG) or 3 months (diesel). BS6 vehicles emit less and may get longer validity. Always renew before expiry. Track expiry on mParivahan app or Vahan portal.
How to Get PUC Certificate
Visit any authorized PUC testing center (at petrol pumps, garages, RTO-authorized centers). Process: Vehicle exhaust emission tested using analyzer probe inserted in exhaust pipe. Takes 5–10 minutes. Cost: ₹60–₹100 for two-wheelers; ₹100–₹150 for four-wheelers. Certificate issued immediately with QR code. Center uploads data to Vahan portal automatically.
What to Do if Vehicle Fails PUC
If vehicle fails emission test: Get engine serviced — check air filter (clogged = rich mixture), spark plugs, fuel injectors, oxygen sensor. Ensure engine oil is not burnt. For diesel: Check injector health and EGR valve. After servicing, retry PUC within the same center on the same day (often no extra charge). Persistent failure may indicate serious engine issues needing mechanic attention.

Common Questions
Do electric vehicles need PUC?
No. Electric vehicles (EVs) have zero tailpipe emissions and are therefore exempt from PUC certificate requirements under the Motor Vehicles Act. This is one of the regulatory benefits of owning an EV. However, EVs still require insurance, registration, fitness certificate (after 15 years for private), and valid driving licence.
