Crash Weighting Research Plan: Will crash weighting improve the capability of FMCSA to identify high crash-risk motor carriers?

The Federal Motor Carrier Safety Administration (FMCSA) is conducting a research study to better understand the safety benefits of adjusting crash weights in the Safety Measurement System (SMS) based on the carrier’s role in the crash (i.e., preventability). The Crash Indicator in SMS currently utilizes all crashes. This safety measurement area has proven to be one of the better predictors of future crash risk. FMCSA is considering modifying the Crash Indicator to weight crashes not only based on severity and timeliness but also on the role of the motor carrier in the crash. The planned research study will provide necessary insight to ensure Agency decisions related to the development of a crash weighting process are based on sound analysis and science. The research will focus on answering the following key questions: (1) Do police accident reports (PARs) across the nation provide sufficient, consistent, and reliable information to support crash weighting determinations? (2) Will a crash weighting determination process offer an even stronger predictor of crash risk than crash involvement and how will crash weighting be implemented into SMS? (3) How would the Agency manage the process for making crash weight determinations including public input to the process? The Agency’s approach toward answering these questions in the planned research study is described in this document.
