A PUC (Pollution Under Control) Certificate is a mandatory document for every vehicle owner in India. It is issued by authorized emission testing centers across the country and states that the vehicles emission levels are within the permissible levels set by the government. The certificate is issued after a thorough examination of the vehicles exhaust gas, and the test results are mentioned in the certificate. The PUC certificate is mandatory in India to ensure that the vehicles emission levels comply with the pollution norms. Every motor vehicle (two/three/four-wheelers) must have a pollution certificate, irrespective of fuel type. According to the Motor Vehicles Act, 1988, a PUC Certificate is mandatory to drive a vehicle legally on the roads. The validity of the PUC Certificate for a new car or bike is one year, and the certificate must be renewed at regular intervals. The certificate is issued after the vehicle undergoes a pollution test to check the emission levels at an authorized center. A vehicle owner must possess documents such as the car insurance policy, registration certificate, driving license, and PUC certificate. A PUC certificate is one of the most important documents one carries while driving a car on the road, and not having it can result in penalties for the vehicle owner.
