Emissions inspections are a type of vehicle inspection that some states require in addition to a safety inspection or on its own. Emissions inspections help to improve air quality by identifying vehicles in need of repair or alteration to lower their pollutant emissions into the environment. Where emissions tests are required, drivers must take their vehicle to a licensed mechanic or dealership to have the inspection performed. To learn more about inspections and emission tests, see our Inspection and Emissions Tests Guide.
