Crash Reporting Research


To assess the completeness of the Federal Motor Carrier Safety Administration’s (FMCSA’s) Motor Carrier Management Information System (MCMIS) crash database and associated collection issues.


The project seeks to estimate the rate of crash reporting completeness in MCMIS and to develop recommendations for improving the reporting of FMCSA-reportable crashes.


The study reviewed the State Data Quality Reports and collected and analyzed a sample of carriers’ crash records. Those records were then compared to the MCMIS crash records. The period of performance was from October 2014 to April 2016.


The research will lead to an estimate of the crash reporting completeness in MCMIS and will develop methods to improve the processes for collecting reportable crashes.
