Here’s why it is important:

• Helps keep the environment clean by ensuring vehicles do not emit harmful gases.
• Reduces vehicle emissions and improves overall air quality which contributes to public health.
• Driving without a valid PUC certificate can lead to fines and penalties.

Vehicle owners must renew their PUC certificates before expiration to ensure that they follow the emission norms and prevent any legal penalties.

The PUC Certificates of new vehicles must be renewed after 1 year. Since the PUC validity period for old vehicles is 6 months, these vehicles must undergo emission level tests every 6 months to have a PUC Certificate.

That is, the vehicle must undergo an emission test at your nearest emission testing center.

Benefits of a Pollution Under Control Certificate

Aside from being a legal requirement, there are several benefits to having a PUC Certificate:

• Enhances the resale value of your vehicle, as it shows that you follow the emission norms and well-maintained vehicle.
• Supports the renewal of vehicle insurance policies, ensuring that your vehicle meets emission standards before policy continuation.
• Frequent emission checks can indicate the health of your vehicle's engine and emission system, allowing for timely maintenance and repairs.

Documents Required for a PUC Certificate

​To obtain a PUC Certificate in India, you typically need to provide the following document at an authorized emission testing center:​

• Vehicle Registration Certificate (RC): It provides essential details about your vehicle, such as its registration number, owner information, and vehicle specifications.

Although this is the primary document required, you can also carry additional vehicle-related documents such as driving license, insurance papers, etc for verification.

This is because, sometimes testing centers may ask for these and therefore it is advised to keep them in hand if the need ever arises.

As per the Central Motor Vehicle Rules, 1989, it is mandatory for all vehicle owners in India to have a PUC Certificate. The PUC Certificate ensures that vehicles comply with emission standards and do not harm the environment.

Regular PUC tests help monitor and control vehicular emissions, thereby contributing to reduced air pollution and a healthier environment. Furthermore, these tests help identify the vehicle's engine performance and emission system which helps in timely repairs.

All types of motor vehicles in India that run on fuel—petrol, diesel, CNG, or LPG—are required to have a valid PUC Certificate.
