How to Get a PUC Certificate for your Vehicle (Car and Bike)

Team AckoMay 24, 2024

Having a valid Pollution Under Control (PUC) certificate is mandatory for all vehicles in India, yet many vehicle owners need to pay more attention to this requirement. A PUC certificate helps ensure your vehicle meets the prescribed emission standards, reducing air pollution. Just like a PUC certificate, it is also crucial that vehicle owners have a valid car insurance plan.


Getting this certificate for your car or bike is quite simple - all it requires is a simple emission check at authorised PUC centers nationwide.

In this guide, we'll walk you through the step-by-step process of getting a PUC certificate seamlessly.



The Harmful Effects of Vehicle Pollution on Our Health and Environment

Vehicular emissions are one of the major contributors to air pollution in India. The dangerous gases released from the exhausts can severely affect our health and the environment.

These pollutants comprise a toxic mix of nitrogen oxides, sulfur oxides, carbon monoxide, benzene, and particulate matter. Long-term exposure to these can lead to aggravated respiratory diseases like asthma and lung cancer. The particulates can enter the bloodstream and increase risk of heart attacks and strokes. Children and the elderly are especially vulnerable.

The pollution also gets absorbed in water bodies and soil, causing acid rain that damages forests and agricultural crops. It reacts with the ozone layer, causing holes leading to climate change effects like increased UV radiation and greenhouse effect. Many studies have linked vehicular fumes to developmental disorders in kids and even a reduction in life expectancy.

By following emission norms and getting timely PUC checks, we can reduce this immense harm to human health and the environment. The tests ensure our vehicles comply with the pollution standards, so it's the duty of each citizen to acquire and renew this basic certificate.

What is a Pollution Under Control (PUC) Certificate?

The PUCC full form is the "Pollution Under Control Certificate." 

It is a mandatory document for every vehicle owner in India. This certificate states that you can legally ride/drive a vehicle in India with respect to meeting environmental standards. In other words, it is a validation document that states that the vehicle’s emission levels are within the permissible levels set by the government.

The PUC Certificate is issued by the authorised emission testing centres across the country. The issuance of an emission test certificate involves a thorough examination of the vehicle’s exhaust gas, and the test results are mentioned in the vehicle pollution certificate.

Why is a PUC Certificate Mandatory in India?

The PUC certificate of vehicle is mandatory in India to ensure that the vehicle’s emission levels comply with the pollution norms. Every motor vehicle (two/three/four-wheelers) must have a pollution certificate, irrespective of fuel type.

The Motor Vehicles Act of 1988 states that the pollution certificate for vehicles is a mandatory document to drive your vehicle legally on the roads.

It is an essential document since it determines the amount of carbon emissions the vehicle produces, which is one of the key contributing factors to rising air pollution.

PUC Rules and Regulations in India

Here are the rules and regulations related to pollution certificates for vehicles. Note that these are subject to changes.

  • The permissible emission levels for vehicles are fixed under Rule 115 (2) of The Motor Vehicles Act, 1988.

  • The acceptable emission levels for vehicles keep changing on a regular basis as per the government’s directives to keep the pollution levels in check.

  • ARAI (Automotive Research Association of India) rolls out directives related to examining vehicle exhaust emissions, limits, and updated regulations.

  • The PUC norms and the certificate format remain the same across the country.

  • If the vehicle fails the PUC test (emission levels exceed the permissible level), the testing centre can issue a rejection slip.

  • Under circumstances of non-compliance to the pollution norms, the registration authority can suspend the RC (Registration Certificate) and any other permits (with reasons recorded in writing) of the vehicle till the owner obtains a valid pollution certificate.

Contents of the PUC Certificate

A Pollution Under Control Certificate contains the following details -

  • PUC Certificate serial number: This is a unique number assigned to each PUC certificate issued to track and identify the certificate.

  • Vehicle details (registration number): The registration number, make, model and other details of the vehicle are mentioned to link the PUC certificate to the specific vehicle it is issued for.

  • The date of the emission certificate test: The date on which the emission test was conducted on the vehicle and the PUC certificate was issued is clearly specified.

  • Validity of the vehicle pollution certificate: The validity period (typically 6 months or 1 year) during which the PUC certificate is valid before the test needs to be repeated is shown.

  • Emission test readings: The actual readings of the emission test for factors like CO, HC etc that were recorded by the testing machine during the test are displayed to allow cross-verification.

How long is your PUC Certificate valid?

The validity of the Pollution Under Control Certificate is limited, and it differs for new and old vehicles. Here are more details about the validity of the PUC Certificate in India.

Technological Innovations in Emission Testing

The process of emission testing for vehicles has seen some noteworthy technological innovations over the years. These have served to make the tests more accurate and efficient.

Upgrade to Automated Testing Stations

The old manual testing system has given way to automated testing equipment at authorised PUC centers. This reduces human error and discretion during testing. The automated machines directly upload test readings to a centralised server for scrutiny.

Improved Testing Protocols

The testing methods have been standardised nationwide based on vehicle type and fuel used. This includes measurement of specific pollutants like CO, HC and smoke density through sensors inserted in the exhaust stream. Upgraded software algorithms analyse emissions accurately.

Tamper-proof Systems

Sophisticated sensors can now detect any tampering with a vehicle's emission control equipment or false reporting of test readings. This has reduced corruption and authenticates the PUCC better.

Integration with Databases

Emission testing systems are now interconnected with regional and national transport databases for easier access to vehicle records and owner details. This aids in the enforcement of PUCC compliance.

The technological upgrades have brought more accountability, reliability, and efficiency to the vehicle emission testing regime. For vehicle owners too, obtaining a genuine PUCC has become easier.

Should I carry the PUC Certificate while driving the vehicle?

Yes, you must carry a copy of the PUC Certificate (soft or hard copy) while driving the vehicle. As per the rules and regulations of The Motor Vehicles Act, the pollution certificate is a mandatory document to drive a vehicle legally in India. You can be penalised if you fail to produce the PUC Certificate during a general inspection.

Penalties for not obtaining a Pollution Under Control Certificate 

According to The Motor Vehicles Act, a PUC Certificate is mandatory to drive a vehicle in India. Not complying with the rules and regulations can attract penalties under Section 190 (2) of The Motor Vehicles Act. The penalty for not obtaining a PUC Certificate stands at Rs. 1,000 for the first-time offence. For a repeat offence, the penalty inflates to Rs. 2,000. Note that the penalties can also vary from one state to another.

The enforcement of PUC norms has been stepped up across many cities:

  • In Delhi, over 57 lakh vehicles were fined in 2022 alone for not having a valid PUC certificate, compared to just 91,000 cars in 2021. This massive increase in crackdown highlights the serious consequences of non-compliance.

  • Bengaluru traffic police recently launched special drives and fined over 6 lakh vehicles not conforming to emission norms in just 45 days.

  • Surat traffic police is setting up PUC checking camps at petrol pumps and busy intersections to catch non-compliant vehicles. Over 60,000 vehicles have been booked here.

The numbers speak for themselves. With environment conservation becoming paramount, enforcement agencies are proactively catching vehicles flouting PUC rules. As a responsible citizen, it's not just important, but crucial to get your vehicle tested and obtain a valid certificate. Non-compliance can lead to not just hefty fines, but also the immobilisation of your vehicle, and even the cancellation of vehicle registration in extreme cases. Being aware of the laws and adhering to them is the need of the hour.
