Abstract:This report is part of a series evaluating the data reported to 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 incomplete. This report examines the
factors that are associated with reporting rates for the state of North Dakota.
MCMIS Crash File records were matched to the North Dakota crash file to determine the nature
and extent of underreporting. Overall, it appears that North Dakota is reporting 64.2 percent of
crash involvements that should be reported to the MCMIS Crash file. There is also evidence that
about 17 percent of the records reported do not meet the reporting standard.
Reporting rates were found to be related to crash severity, the configuration of the vehicle, and
the type of enforcement agency that covered the crash. Over 93.3 percent of fatal crashes were
reported, 81.8 percent of injury/transported crashes, and 57.5 percent of tow/disabled
involvements. More than 72 percent of reportable involvements of truck-tractors were reported,
but the reporting rate was 47.4 percent for 2-axle, 6-tire single-unit trucks. Only 30.8 percent of
bus involvements were reported.
Missing data rates are low for most variables. Overall, the crash report is well-designed to
support full reporting. The information necessary to identify reportable cases is available in the
crash file, so a substantial improvement in the reporting rate can be achieved.
