The report reviews six possible explanations for low reported failure rates in manual, decentralized Inspection/Maintenance (I/M) programs. The report analyzes and discusses random roadside idle survey data, reported I/M program data and data collected during audits of I/M programs. The data indicate that five of the explanations: quality control, fleet maintenance, differences in fleet mix or emission standards, anticipatory maintenance, and pre-inspection repair, do not sufficiently explain low reported failure rates. The report concludes that the major problem contributing to low reported failure rates in decentralized, manual, I/M programs is improper inspections by test station personnel.
