The goals of this study are to: (1) understand the impact of maintenance on safety-based crashes; (2) determine the maintenance standards of best performers; and (3) determine the range and role of annual State inspection programs.
Vehicle maintenance (e.g., brakes, lights, other mechanical defects, and load securement) is one of the seven Behavior Analysis and Safety Improvement Categories (BASICs) for motor carrier safety measurement. In January 2014, FMCSA published the Carrier Safety Measurement System (CSMS) Effectiveness Test by BASICs Study. This published study showed that motor carriers targeted for interventions due to vehicle maintenance have a 65 percent greater future crash rate than the national average.
The current study is analyzing the impact of preventative vehicle maintenance of large trucks and buses on safety, to include not only violations that are serious enough to be listed as out-of-service (OOS) criteria, but also other vehicle maintenance issues which have been found to cause or contribute to crashes.
A report that analyzes the impact of vehicle maintenance on safety and recommends whether new or revised OOS criteria are needed. Additionally, a review of inspection and maintenance practices of States and safe carriers, respectively.
