What is emissions testing?

Emissions testing is a process where a vehicle's exhaust is analyzed to measure the amount of pollutants it emits, such as carbon monoxide, nitrogen oxides, hydrocarbons, and particulate matter. The goal is to ensure that vehicles meet environmental standards set by local or national authorities to help reduce air pollution. Emissions testing is often required as part of regular vehicle inspections, and vehicles that don't pass may need repairs before they can be legally driven. These tests help ensure cleaner air and a healthier environment for everyone.
