Why Do We Need a PUC?

For a two-wheeler to be fit to be driven on the road, it must be ensured that the pollution generated by the vehicle is under control. You must check with the designated authorities to know whether the emissions are under the legally allowed amount. If the emissions from vehicles aren't kept under control, then they can damage the environment. In 1989, the government also and the PUC mandatory for every two-wheeler.

What is the procedure to obtain a PUC?

PUC is furnished only to two-wheelers which pass the emission test. Several petrol pumps have personnel and equipment. This personnel is trained to administer an emission test. Apart from petrol pumps, there are many independent test centers which conduct emission tests for the vehicles. In emission tests, the sanctioned amount of hydrocarbons and carbon monoxide released per ppm is measured and it is checked if the vehicle is exceeding the permissible amount.

How Long is the PUC Valid?

The PUC is valid for one year since the date of issue.
