Vehicle Emissions Testing Program
The IDEM vehicle emissions testing program was instituted to reduce pollutants released into the air from mobile sources like cars. Both motor vehicle exhaust and gasoline vapors contribute to the formation of ground level ozone. When breathed, ground level ozone can trigger a variety of health problems for sensitive people of all ages but especially young children and the elderly. Ecosystems and delicate plant life can also be harmed by ground level ozone. The vehicle emissions testing Clean Air Car Check Program has served the public well by identifying vehicles that emit harmful pollutants. Once repaired, these vehicles not only pollute less but often experience better performance and fuel economy. The vehicle emissions testing program is currently helping those in Northwest Indiana breathe cleaner air.
