OVERVIEW OF BRITISH COLUMBIA'S MOTOR VEHICLE INSPECTION AND MAINTENANCE PROGRAM

Inspection and maintenance (I/M) programs are a control option for in-use vehicle emissions. They are designed to reduce air pollution in urban areas by identifying and correcting, through repairs, excessive in-use emission levels. They act a a deterrent to vehicle tampering and insufficient maintenance, and enforce provincial anti- tampering legislation. I/M programs are a compulsory, regularly scheduled emission inspection of vehicles registered in a designated area. The I/M test usually consists of a visual inspection of the emission control components on a vehicle, and an exhaust emissions measurement. A vehicle which fails the test must be repaired, usually up to a maximum repair cost limit (waiver). This paper look at British Columbia's I/M program, called AirCare.
