What is 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 authorized by the state government.
- These issue certificates if a vehicle is found complying with the prescribed emission norms.

- A gas analyzer is connected to a computer, to which a camera and a printer are attached.

- Subsequently, a certificate may be issued if the emission values are within the limits.
