Emissions tests on cars typically involve measuring the levels of pollutants emitted from the vehicle's exhaust system while it's running. During the test, vehicles are usually placed on a dynamometer, which simulates road conditions, and sensors analyze exhaust gases for substances like carbon monoxide, nitrogen oxides, and hydrocarbons. Some tests may also include an on-board diagnostic (OBD) check to evaluate the vehicle's emission control systems. The results determine if the vehicle meets regulatory standards for emissions.
