Pollution Certificate for Diesel and Petrol Vehicles: Guidelines and Differences

Over time, humans have made significant progress in various fields, including the vehicle industry. However, this progress has come at the cost of a severe decline in air quality, leading to environmental degradation. The increasing number of vehicles on the road is a major contributing factor to this issue. As responsible members of society, it is important for us to fulfill our role and obtain a Vehicle Pollution Certificate for our vehicles. This is why, in India, you need to have a Pollution Under Control (PUC) certificate. 

Pollution Certificate for Diesel and Petrol Vehicles: Guidelines and Differences

What is a Vehicle Pollution Certificate?

This certificate is issued by the government to verify that your vehicle's emission levels are within the acceptable limits set by pollution regulations. In accordance with the Motor Vehicle Act in India, all vehicle owners must possess this certificate. Furthermore, renewing your motor insurance policy requires a valid pollution certificate, as specified by the Insurance Regulatory and Development Authority of India guidelines. Please note, however, that the absence of a valid Pollution Under Control (PUC) certificate is not a valid reason for denying a claim under a motor insurance policy, as clarified by the IRDAI guidelines.

PUC Certificate Inclusions

The pollution under control certificate includes the following information:

  • Serial numbers indicating the date of the last conducted test
  • The registration number of the vehicle.
  • The vehicle’s License Plate Number
  • The date of the pollution test and its expiry date
  • Emission test readings

Pollution Certificate Test Procedures:

Below is the procedure for the pollution certificate test. 

  1. If the vehicle is new, the motor dealer will arrange for the PUC certificate.
  2. For renewal, you will have to take the vehicle to an authorized petrol pump.
  3. The petrol pump will first check the emission level from the car/bike's exhaust pipe.
  4. To analyze carbon emission, a device will be inserted into the vehicle's ignition, and the engine will be accelerated.
  5. For diesel vehicles, the accelerator is fully pressed, and this process is repeated five times. The final reading is the average of all the readings.
  6. For petrol vehicles, the car is kept idle without pressing the accelerator. Only a single reading is noted as the final reading.
  7. Pay the applicable fees, and then you may collect the pollution certificate.

Cost and Validity of Pollution Control Certificate

The validity of a pollution certificate varies for old and new vehicles.

  • A new car or bike pollution certificate is valid for one year, after which it needs to be renewed every 6 months by obtaining a new certificate from any emission testing center.
  • If a vehicle fails to meet the pollution control test standard, the validity of the renewed certificate can be canceled before 6 months.

Check out the details related to the cost of a pollution certificate below: 

The cost of a pollution certificate for a car or bike ranges from Rs. 60 to Rs. 100, depending on the kind of vehicle and fuel. The price may vary from state to state.

Pollution under Control Rules and Regulations in India

  • According to Rule 115 (2) of the Motor Vehicles Act, there are specific limits for vehicle emissions that must be followed.
  • The government regularly updates the acceptable emission levels for vehicles based on pollution levels, as directed by the Automotive Research Association of India.
  • The format and norms of the pollution certificate remain the same across the country.
  • If a vehicle fails the PUC test, indicating that its emission levels exceed the permissible level, the testing center can issue a rejection slip. 
  • The registration authority has the power to suspend the Registration Certificate (RC) and any other permits of the vehicle until the owner obtains a valid pollution certificate in cases of non-compliance with the pollution norms.


Penalties for not obtaining a PUC Certificate

As per the Motor Vehicles Act, possessing a pollution certificate is mandatory for driving a vehicle in India. Non-compliance with the rules and regulations can result in a penalty under Section 190 (2) of The Motor Vehicles Act. For a first-time offense, a fine of Rs. 1000 will be imposed. Subsequent offenses will incur a fine of Rs. 2000.
