How the Clean Air Act “Hits Home” Through the I&M Program

Atlanta’s Inspection & Maintenance program effectively screens dirtier vehicles out of the fleet. It must be noted, however, that failure rates are sufficiently low for the bulk of the tested fleet that the vast majority of tests accomplish little and the reliance on diagnostic computers (rather than actual tailpipe emissions) is problematic as vehicles age – precisely when better screening is most important. Households tend to “shop” for inspection stations to minimize their costs – thus picking stations nearby their homes and those that are more lenient. The program imposes a burden on those who own dirty cars, and those cars are clearly owned by poorer households.
