Q: Which vehicles are needed to undergo a PUC testing?

Gasoline powered vehicles: All gasoline powered vehicles need to undergo a regular PUC testing in order to ensure that they are not emitting excessive levels of pollutants. Diesel powered vehicles: Even diesel vehicles, especially the older models emit high levels of particulate matter other than pollutants. They need to undergo a PUC test to ensure compliance with the local emission standards. Vehicles with high engine capacity: Then there are vehicles which have high engine capacity. Some regions need PUC tests done for their vehicles having large engine capacities. Such vehicles are likely to emit higher levels of pollutants. Commercial vehicles: Commercial vehicles like trucks, buses, autos and taxis also emit many pollutants, for which they too need to undergo a PUC test and ensure compliance with the local emissions standards. Vehicles which are aged: Vehicles which are more than a certain age need PUC testing done on them too, as they often emit pollutants. Overall, it is mandatory to check with the local regulatory authorities and determine whether the vehicles need to undergo a PUC test and how often it is needed.

Question 1

What is a Pollution Control Certificate (PUC)?

Accepted Answer

A PUC Centre is a facility where the vehicles are tested for emissions. This is to ensure that they comply with the pollution control regulations.

Question 2

Why is PUC mandatory in India?

Accepted Answer

The reason why PUC is mandatory in India is to help control air pollution. A major increase in vehicles is the main source of air getting polluted and the emissions the vehicles produce can have harmful effects on the environment and human health. In order to reduce the amount of harmful pollutants released into the air, the Indian Government has made it mandatory for vehicle owners to meet the permissible standards of automobile emission and get a PUC certificate.

Question 3

What happens if the PUC test fails?

Accepted Answer

There are certain consequences if a PUC test fails and can vary as per the location and type of test performed. These are as follows:
A failed emission test can result in the vehicle getting flagged as a non-compliant vehicle and the owner needs to make repairs to bring the emission level into compliance. Such specific repairs needed depend on the cause of the failure, and may include things like repairing a malfunctioned oxygen sensor or a faulty catalytic converter.
As per the severity of the emissions violations, a failed PUC test can result in fines or in penalties which are levied against the owner of the vehicle. The amount of fine also varies as per the location and specific emission standards which are in place.
There are some cases where a vehicle fails emission testing repeatedly and the owner is not able to bring the vehicle into compliance, then the vehicle needs to be taken off the road and scrapped.

Question 5

Where can the PUC test be conducted?

Accepted Answer

PUC testing is conducted at authorized testing centres equipped with the necessary equipment to perform the emissions test.
Some of the locations where PUC testing are conducted include:
Government approved testing centres: A lot of regions have government approved testing centres which are authorized to perform a PUC testing. Such centres can be operated by the Government or by any authorized third party vendors.
Service stations and private garages: Some service centres and private garages can be authorized for performing a PUC testing. Such facilities have equipment and such personnel trained to perform such PUC tests.
Mobile testing vans: there are mobile PUC testing vans in some areas, which are deployed to offer testing services in remote areas.
Thus, it's important for any vehicle owners to check with the local authorities or with the transport department in their area, to find authorized testing centres near them.

Question 6

For which type of vehicle has PUC been issued?

Accepted Answer

PUC is a certificate issued after a vehicle has undergone an emission test to determine whether it is in compliance with the local emission standards. Such certification is issued for motor vehicles like motorcycles, cars, buses and trucks, which use combustion engines and run on petrol, diesel or compressed natural gas.

Question 7

How can a person find a PUC centre near him

Accepted Answer

There are many PUC centres which are licensed and regulated by the local authorities. He can either search online or call his local transportation or environmental agency for details on licensed PUC centres nearby his residence.

Question 8

How can a person help reduce vehicular emissions

Accepted Answer

There are many things a person can do to help vehicular emission reduction. He can use public transportation, opt for carpooling, maintain his vehicle properly and drive in an efficient manner. Other than that, he can support policies and initiatives which promote clean and sustainable transportation options.

Question 9

What are the advantages of PUC?

Accepted Answer

There are numerous advantages of Pollution Under Control testing. They are as follows:
Improvised public health: PUC testing reduces air pollution and helps improve public health by reducing the risk of respiratory or such health issues which are connected with exposure to pollutants.
Reduction in air pollution: PUC testing reduces air pollution, thus improving air quality substantially.
Compliance with the local regulations: Many regions need PUC testing as it is required by law and failure to do so with such regulations can result in fines and such penalties. With PUC testing that ensures compliance with the local regulations, a vehicle owner can avoid such penalties
Better fuel efficiency: With the help of such testing, one can identify the vehicles which are not operating at optimal fuel efficiency. This can result in higher emission and fuel consumption. With PUC Tests one can identify and repair such issues and even improve the efficiency of fuel, thus reducing emissions.
Improved vehicle performance: PUC tests help identify issues that are related with the engine of the vehicle, which can impact the overall vehicle performance. When such issues are identified and repaired, the overall performance of the vehicle improves.

Question 10

What PUC certificate contains?

Accepted Answer

A Pollution Under Control certificate is a certificate which a vehicle owner obtains after his vehicle goes through PUC testing. In India, these certificates are issued to vehicles which pass the pollution test to measure the level of pollutants emitted by the vehicle’s exhaust.
The PUC certificate contains the following details:
The registration number, the engine number, chassis number and the date of the test. It also has the emission level measured during the test and the result of the test, whether pass or fail.
This certificate also has the expiry date of the certificate after which the vehicle needs to be tested again, in order to maintain compliance with the emission standards. The serial number of the certificate and the license plate number of the vehicle are also in the certificate.
