PUC Certificate Validity and Cost

Validity and Cost:


When you purchase a new car, a PUC certificate is provided for it and the validity of this certificate is 1 year. Following that your car would need to undergo the PUC test at regular intervals and a new certificate will be issued each time.


The validity of the new certificate is usually 6 months. In case an adverse reading is observed in the PUC test, the validity of the certificate will be decided on the basis of that reading.


If cars exhibit higher levels of emission than the prescribed limits, the registration number of the vehicle will be informed to the RTO, Deputy RTO or Assistant RTO by the testing centre within one day.



The cost of the PUC test is quite minimal. It varies from Rs. 60 to Rs. 100, based on the vehicle that is being tested and its fuel type.



Major Changes in BS6



Amongst all the changes the major changes in new engines are:

Installing additional DPF (Diesel Particulate Filter) in the exhaust systems to reduce the Sool or Particulate matter.

Controlling SOx (Sulphur Oxides) by removing the sulphur content from the diesel fuel



Petrol Engines



The vehicles running on petrol now get more advanced OBD (On-Board Diagnostics).

Getting realtime emission updates is an addon feature.
