The FARS/MCMIS Fatal Crash Record Matching Tool is designed to help reconcile differences between the Fatality Analysis Reporting System (FARS) and Motor Carrier Management Information System (MCMIS) databases. A methodology was developed to "match" fatal large truck and bus crash records between the FARS and MCMIS databases. The methodology defines a "matched record" between the two databases as a crash that involved at least one fatality, involved a large truck or bus, and contains the same information in several key fields (e.g., county, date, time, VIN, DOT #, etc.). The methodology has more than 40 unique matching combinations that can produce a single match between FARS and MCMIS fatal crash records.

The FARS record set also contains records from the FARS’ Parkwork data set, which includes information about parked and working vehicles involved in fatal crashes. A "parked vehicle" is defined as a motor vehicle that was stopped off of the roadway when it became involved in a fatal crash. A “working vehicle” is defined as a motor vehicle that was in the act of performing highway construction, maintenance, or utility work related to the traffic way when it became involved in a fatal crash.
