What is a PUC Certificate?

A Pollution Under Control Certificate (PUC Certificate) is an approval that emission from a vehicle is under control and as per the pollution norms. The document is issued by the government after a thorough inspection of the vehicle’s emissions level.

As per the Motor Vehicle Act, a PUC certificate is now required to be carried while driving, along with a registration certificate, a motor insurance policy, and a driving licence.

Why is a PUC certificate required?

Apart from complying with traffic rules, there are a few important reasons why an emission certificate is required:

Mandatory as per law

In accordance with the Central Motor Vehicles Act, 1989, a vehicle must have a Pollution Certificate, which must be renewed when it expires. By failing to comply with this, you may be subject to penalties from the traffic police as well as the Regional Transport Authorities (RTOs). PUCs are government-issued approvals that your vehicle’s emission levels are within prescribed limits.

To curb pollution

Motor vehicle emissions that exceed permissible levels can be harmful to the environment and to people’s health. Hence, every citizen must adhere to the government’s pollution levels for two-wheelers, three-wheelers, and four-wheelers. Obtaining a PUC certificate or conducting an emission test ensures that vehicles do not exceed permitted pollution levels.

PUC certificates: What are the costs and validity?

You should be aware of the validity and cost of the PUC of your vehicle.

  • A PUC certificate is valid for one year for a new car or bike. You will need to renew it on a regular basis.
  • The new certificate has a validity of six months for both cars and bikes. If the PUC test yields an adverse result, the validity of the certificate will be determined by that result.
  • If a car emits more CO2 than the permissible limit, the testing centre will notify the RTO, the Deputy RTO, and the Assistant RTO within one business day.
  • PUC tests are quite inexpensive. Depending on the fuel type and the vehicle being tested, the fee varies from Rs. 60 to Rs. 100.

PUC test procedure

  • With diesel vehicles, the engine is fully accelerated, and the pollution levels are monitored. Five readings are done, and the average is taken as the result.
  • Unlike with diesel vehicles, petrol vehicles may idle without applying the accelerator. This reading represents the final result.

Test criteria and certificate

PUC tests should be conducted on all vehicles within the following limits.

Vehicle Type Hydrocarbon measured in ppm CO Percentage
Two and three-wheeled vehicles (2 or 4 strokes) made on or before 31st March 2000 9000 4.5
Two and three-wheeled vehicles (2 strokes) made on or before 31st March 2000 6000 3.5

Four-wheeled vehicles made as per the Pre Bharat Stage II Norms 1500 3
Four-wheeled vehicles made as per the Pre Bharat Stage II, Pre Bharat Stage III or subsequent Norms 750 0.5

Testing for PUC can be done at any authorised petroleum pump or independent testing facility. Certificates are also issued at the testing location.
