The Impact of Non-preventable Crashes on Compliance, Safety, Accountability Scores
The Federal Motor Carrier Safety Administration’s (FMCSA’s) Compliance, Safety, Accountability (CSA) program identifies high risk motor carriers using crash and inspection data in seven Behavioral Analysis and Safety Improvement Categories (BASICs). The Crash Indicator BASIC (“Crash BASIC”) uses all prior crash involvement to evaluate carrier safety; no differentiation is made between crashes which could have been prevented by the actions of the driver and/or motor carrier and those which were non-preventable. As a result, the Crash BASIC may not accurately represent a carrier’s safety performance. This case study approach models the impact of excluding non-preventable crashes from the Crash BASIC calculation by mapping the crash records of 15 motor carriers to the Motor Carrier Information Management System (MCMIS), then removing five non-preventable crash types from the calculation of the Crash BASIC. Non-preventable crashes comprised 61 percent of the 15 carriers’ crash records, the five identified crash types comprise only a small number of these crashes. The comparison of the FMCSA-generated Crash BASIC with the “adjusted” Crash BASIC that excludes the five crash types shows that removing certain non-preventable crashes impacts carrier measures significantly, shifts of the relative ranking for the 14 motor carriers in the sample in the same peer group. The five crash types represent a small proportion of the carriers’ non-preventable crashes; a broader incorporation of non-preventable crashes would therefore result in even more significant changes to carrier Crash BASIC measures and relative rankings.
