Summary

This document presents a statistical summary of traffic crashes on Michigan roadways for the calendar year 2000, produced by the Michigan Department of State Police and the University of Michigan Transportation Research Institute. The report aims to provide data on crash frequency, severity, and contributing factors to support traffic safety planning and trend analysis. The data was compiled from Michigan Traffic Crash Report Forms (UD-10) submitted by law enforcement agencies, supplemented by information from state departments of transportation and health. The methodology relies on administrative records processed by the Criminal Justice Information Center. However, the report explicitly warns that the 2000 data may not be fully accurate due to processing errors and revisions to reporting forms that compromised specific data elements, including alcohol/drug involvement, farm equipment crashes, and new driver condition metrics like cell phone use. Additionally, the incomplete state roadway location index prevented the identification of roadway types for some crashes. Consequently, the authors advise using the data for trend analysis only and note that alcohol-related figures cannot be directly compared to prior years due to changes in how drug and alcohol involvement were recorded. Key findings indicate that Michigan recorded 1,382 traffic fatalities in 2000, a 0.3 percent decrease from 1999, while total crashes increased by 2.2 percent to 424,852. The death rate remained stable at 1.5 deaths per 100 million vehicle miles traveled, matching the 1999 rate and falling below the ten-year average of 1.6. Exposure factors, including vehicle registrations and travel mileage, increased by approximately 2 percent. Alcohol remained a significant factor, involved in 32.9 percent of fatal crashes and 44.1 percent of alcohol-related crashes resulting in injury or death. Single-vehicle crashes accounted for 45.3 percent of all fatal crashes and 62.2 percent of alcohol-related fatal crashes. Excessive speed was cited as a hazardous action in 11.8 percent of fatal crashes. Demographic data showed that drivers under 25 comprised 24 percent of those involved in fatal crashes, and motor vehicle crashes were the leading cause of accidental death for teenagers and young adults. The significance of this report lies in its provision of baseline statistics for evaluating traffic safety interventions in Michigan, despite noted data quality limitations. It highlights the persistent impact of alcohol impairment and single-vehicle incidents on fatality rates. By documenting trends in exposure, crash types, and demographic vulnerabilities, the report supports the Office of Highway Safety Planning’s mission to reduce injuries and fatalities through targeted policy and program support. The caution regarding data comparability underscores the importance of methodological consistency in longitudinal traffic safety research.

Key finding

In 2000, Michigan recorded 1,382 traffic fatalities and 121,826 injuries across 424,852 crashes, with alcohol involvement present in 32.9 percent of fatal incidents.
