Emission Test for Two-Wheelers in India

Team AckoApr 10, 2024

In recent years, the issue of air pollution has become a growing concern in India, particularly in densely populated urban areas. Two-wheelers, such as motorcycles and scooters, are a common mode of transportation in the country and contribute significantly to air pollution. To address this issue, the government of India has implemented stringent emission testing regulations for two-wheelers aimed at reducing harmful pollutants and promoting sustainable mobility. 

This article explores the emission testing process for two-wheelers in India, its significance, and the positive impact it has on the environment.

What is Emission Test for Two-Wheelers?

The emission test for two-wheelers is a procedure designed to measure and evaluate the level of harmful pollutants emitted by two-wheeler vehicles. It is conducted to ensure that these vehicles comply with the prescribed emission standards set by regulatory authorities. The test aims to identify and regulate the emission of pollutants such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) from two-wheelers.

During the emission test, the vehicle's exhaust gases are analysed to determine the concentration of these pollutants. The test helps in assessing the environmental impact of two-wheelers and plays a crucial role in monitoring and controlling air pollution caused by vehicular emissions. By enforcing emission standards, authorities aim to reduce pollution levels and promote a cleaner and healthier environment.

Process of Emission Testing for Two-Wheelers

To ensure compliance with the emission standards, two-wheeler owners need to undergo the emissions testing process. Here's a step-by-step breakdown of the process.

Preparing for the Test

  • Ensure your two-wheeler is in proper working condition, as any mechanical issues may affect the test results.

  • Verify the documents required for the test, such as the vehicle registration certificate, insurance certificate, etc.

Visiting the Authorised Testing Centre

  • Locate a nearby authorised testing centre approved by the government authorities.

  • Schedule an appointment or visit during their operating hours.

Emissions Test Procedure

  • The testing centre will conduct the emissions test using specialised equipment.

  • Your two-wheeler will be connected to the emissions testing equipment, which will measure the levels of CO, HC, and NOx.

  • The results will be recorded, and the emissions levels will be compared against the prescribed limits.

Test Result and Certificate

  • Based on the test results, you will receive a test report and a certificate indicating whether your vehicle meets the emission standards.

  • If your two-wheeler complies with the emission norms, you will be issued a valid certificate.

  • In case of non-compliance, you will be provided with information on necessary repairs or adjustments to meet the standards.

Emission Standards for Two-Wheelers in India

The emission standards for two-wheelers in India are regulated by the Central Pollution Control Board (CPCB) and are based on Bharat Stage (BS) norms. These norms dictate the permissible limits for various pollutants emitted by two-wheelers. As of September 2021, India follows the BS-6 emission standard, which is the most stringent and advanced stage.

The Bharat Stage standards are based on European emission norms and are implemented to control and reduce the emission of pollutants from vehicles. The BS emission standards set the permissible limits for various pollutants, including carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and particulate matter (PM), emitted by motor vehicles.

The table below provides an overview of the standard emission levels for motor vehicles in India based on the Bharat Stage emission standards.

Emission Standard

CO (g/km)

HC+NOx (g/km)

PM (g/km)

BS-IV

1.0

0.1

0.025

BS-VI

0.5

0.06

0.005

Note: The values provided in the table represent the maximum permissible emission levels for each pollutant.

The transition from BS-IV to BS-VI emission standards marked a significant leap in terms of reducing emissions from motor vehicles. The BS-VI norms are more stringent and require vehicles to emit significantly lower levels of pollutants compared to their BS-IV counterparts. These standards were implemented in a phased manner across the country, with BS-VI emission norms becoming mandatory for all new motor vehicles from April 2020.

It is important to note that the emission levels mentioned above are applicable to different types of motor vehicles, including two-wheelers, cars, buses, and commercial vehicles. Each category of the vehicle has specific emission standards and testing procedures to ensure compliance with the prescribed norms.

Importance of Emission Testing

The following points highlight the importance of two-wheeler emission testing.

  • Ensuring Compliance: Emission testing plays a crucial role in ensuring that two-wheelers meet the prescribed emission standards set by the government. By mandating these tests, the authorities aim to reduce the emission of pollutants such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx), which are known to contribute to air pollution and have adverse health effects.

  • Health and Environmental Benefits: Two-wheelers that pass the emission tests emit fewer pollutants into the atmosphere, leading to improved air quality. This reduction in harmful emissions directly benefits the health of both individuals and the environment, contributing to a cleaner and greener India.

Frequently Asked Questions

Here are a few common questions and their answers related to emission tests for two-wheelers.

How often should I get my two-wheeler emissions tested?

As per regulations, the two-wheeler emissions test should be conducted annually or as per the timeline specified by the regional transport authority.

Can I get my emissions test done at any service centre?

No, it is essential to visit authorised testing centres that are approved by the government to ensure accurate and valid test results.

What are the consequences of not having a valid emission certificate?

Not having a valid emissions certificate can lead to penalties, fines, or even vehicle registration suspension by the authorities.

Where can I get an emission test done for my two-wheeler?

Emission tests for two-wheelers are conducted at authorised testing centres approved by the government. These centres have the necessary equipment and expertise to perform accurate and reliable emission tests.

Are electric two-wheelers exempt from emissions testing?

Electric two-wheelers are exempt from emissions testing as they do not produce tailpipe emissions. However, they may still need to comply with other regulatory requirements.
