Truck and Bus Maintenance Requirements and Their Impact on Safety

Goal:

To further analyze the impact of vehicle maintenance issues (for large trucks and motorcoaches) on safety.

Background:

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 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.

Summary:

The proposed study will further analyze the impact of vehicle maintenance issues (for large trucks and motorcoaches) 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. This proposed study will consider whether new or revised OOS criteria are needed. New or revised OOS criteria may include combinations of vehicle maintenance issues.

Outcomes:

A report that analyzes the impact of vehicle maintenance on safety issues and recommends whether new or revised OOS criteria are needed.
