About PUC Certificate:

  • The PUC certificate is a document that any person driving a motor vehicle can be asked to produce by a police officer in uniform authorised by the state government.
  • A PUC certificate contains information such as the vehicle’s license plate number, PUC test reading, date on which the PUC test was conducted and the expiry date.
  • Authorised pollution checking centres issue certificates if a vehicle is found complying with the prescribed emission norms.

How is a Pollution Control Check Carried Out?

  • The computerised model for pollution check was developed by the Society of Indian Automobile manufacturers.
  • A gas analyser is connected to a computer, to which a camera and a printer are attached. The gas analyser records the emission value and sends it to the computer directly, while the camera captures the license plate of the vehicle. Subsequently, a certificate may be issued if the emission values are within the limits.
