The Road Ahead for Vehicle Emissions Inspection and Maintenance Programs
Abstract
A discussion about vehicle emissions inspection and maintenance (I/M) programs is presented. The National Research Council, vehicle emissions I/M programs are missing opportunities to reduce air pollution by expending too many resources to inspect cleaner low-emitting vehicles and not effectively dealing with the dirtiest ones. I/M programs are designed to identify vehicles that have higher than allowable emissions and ensure that such vehicles are repaired or removed from the fleet.
