摘要：	This is the third in a series of papers presenting the results of an evaluation of the Motor Carrier Management Information System (MCMIS) Crash File undertaken by the Center for National Truck and Bus Statistics at the University of Michigan Transportation Research Institute. The earlier studies showed that reporting to the MCMIS Crash File was significantly incomplete. This report examines the sources of underreporting for the state of Missouri. MCMIS Crash File records were matched to the Missouri Police Accident Report (PAR) file to determine the nature and extent of underreporting. As in other states, it appears that officers are having difficulty applying the vehicle and crash severity criteria that define a MCMIS-eligible case, resulting in underreported cases. In addition, approximately 20%of the Missouri cases were duplicate records. Cases involving a fatality are more likely to be reported than injury or towaway cases. Similarly, crashes involving larger trucks or out-of-state trucks or buses were more likely to be reported than smaller trucks and in-state vehicles. Cases covered by local police departments, primarily in the largest cities, accounted for the majority of underreported cases.
