Vehicle emissions testing

Vehicle emissions testing evaluates a car's exhaust to ensure it meets environmental standards, reducing pollution and health risks. During the test, emissions are measured while the vehicle runs on a dynamometer or on the road. The results determine if the vehicle produces acceptable levels of pollutants like carbon monoxide, hydrocarbons, and nitrogen oxides. If the vehicle passes, it is deemed environmentally compliant; if not, repairs are required to reduce emissions. Regular testing helps maintain air quality and encourages vehicle maintenance for optimal performance and reduced environmental impact.
