Summary

This report, titled *Idaho Traffic Collisions, 2000*, provides a comprehensive statistical analysis of motor vehicle collisions in Idaho for the year 2000. Published by the Idaho Transportation Department’s Office of Highway Safety, the document aims to assist state and local agencies in identifying traffic safety problems and targeting collision reduction programs. The data is derived from the Idaho Transportation Department State Collision Database, which includes collisions investigated by law enforcement resulting in injury, death, or property damage exceeding $750. The report categorizes data by statewide trends, roadway classifications, geographic locations, driver demographics, and specific focus areas such as impaired driving and safety restraint usage. In 2000, Idaho experienced 26,241 total traffic collisions, a 4.6% increase from 1999. While total collisions rose, fatal collisions decreased by 1.6% to 241, and total fatalities dropped slightly by 0.7% to 276. Conversely, injury collisions increased by 1.5%, and property-damage-only collisions rose by 6.6%. The estimated economic cost of these collisions was $1.58 billion, with society bearing over 70% of the costs through insurance premiums, taxes, and public services. A notable trend was the 4.2% decrease in Annual Vehicle Miles of Travel (AVMT), the first decline in two decades, which influenced fatality and injury rates. The statewide fatality rate was 2.01 per 100 million AVMT, while the injury rate was 103.99. The analysis reveals significant disparities between urban and rural environments. Although rural roads accounted for only 41% of all collisions, they were the site of 84% of fatal collisions. Single-vehicle collisions, which comprised 31% of all crashes, accounted for 58% of fatalities; overturns were the leading harmful event in these incidents, with 93% of ejected occupants in fatal rollovers not wearing seat belts. Speed was the primary contributing circumstance in single-vehicle crashes (38%), while inattention/distraction was most prevalent in multiple-vehicle crashes (23%). Geographically, counties with larger populations, such as Ada and Canyon, recorded the highest absolute numbers of collisions, though collision rates varied significantly across smaller counties. The report highlights specific risk factors and demographic trends. Impaired driving, aggressive driving, and youthful drivers are identified as key focus areas for safety interventions. Data indicates that single-vehicle crashes are disproportionately fatal and often involve speed or impairment, whereas multiple-vehicle crashes are more frequently linked to inattention. The document concludes by providing detailed breakdowns by county and city, offering granular data to support targeted highway safety grant programs and policy decisions aimed at reducing the economic and human costs of traffic collisions in Idaho.
