The Florida Motor Vehicle Inspection Program

Abstract

In 1991, Florida implemented the Motor Vehicle Inspection Program (MVIP) mandated by the Florida Clean Outdoor Air Law, which was passed in response to federal requirements for meeting ambient air quality standards. Has the implementation of this law resulted in decreased pollution levels as predicted by proponents of this program? The authors present a quasi-experimental evaluation of this question. Using an autoregressive integrated moving average (ARIMA) intervention model, they show that the implementation of the MVIP has led to a significant decline in ozone (03) levels in some counties but no significant reductions in carbon monoxide (CO) levels in the counties where the program was implemented.
