Title:  

Effectiveness of On-Board Diagnostic (OBD) Testing for Vehicle Inspection and Maintenance (I/M): A Report to the Illinois General Assembly, Executive Summary

 
 Volume/Number:  2003 September 
 Issuing Agency:   
 Description:  Illinois has had a vehicle inspection and maintenance (I/M) program since 1986 to help identify vehicles that are in need of repairs because they exceed air pollution limits. I/M is limited to vehicles registered in metropolitan Chicago and metropolitan East St. Louis, and it is one of Illinois most important tools for improving air quality and meeting federal air quality standards. For example, I/M reduces emissions of ozone-forming volatile organic compounds by 26 tons per day in northeastern Illinois.
