  • Features and Benefits of the Vehicle Emissions Inspection and Maintenance (I/M) Program


  • Air quality in Illinois has improved substantially since 1970 when Congress first passed the Clean Air Act, but air pollution remains a problem. In 1986, Illinois began the vehicle inspection and maintenance (I/M) program in Northeastern Illinois and Metro-East St. Louis to reduce air pollution and help these regions meet federal air quality standards. The I/M program identifies vehicles that need repairs due to malfunctions or poor maintenance which contribute to high emissions rates. Such repairs not only reduce air pollution, they often improve vehicle performance and fuel economy as well.
