Summary

This document presents the Wyoming Department of Transportation’s 2010 Report on Traffic Crashes, a comprehensive statistical analysis of traffic safety data collected throughout the state. The report aims to quantify the frequency, severity, and contributing factors of traffic crashes to inform public safety initiatives and resource allocation. It defines reportable crashes as those resulting in bodily injury, death, or property damage exceeding $1,000, categorizing severity into fatal, injury, and property damage only (PDO) classifications. The methodology relies on aggregated crash data from 2010, supplemented by comparative statistics from 2006 through 2009. The report analyzes variables including crash location (county and city), time of year, environmental conditions (weather, lighting, road surface), vehicle types, driver demographics (age and gender), and specific contributing circumstances such as alcohol involvement and safety equipment usage. Data is segmented by crash severity and collision type, providing a granular view of traffic patterns across Wyoming’s urban and rural landscapes. In 2010, Wyoming recorded 14,653 total crashes, comprising 137 fatal crashes (153 fatalities), 3,159 injury crashes (4,462 injuries), and 11,357 PDO crashes. This represented a decrease from previous years, with total crashes declining from 16,974 in 2006. The economic loss associated with these crashes totaled approximately $3.48 billion. Alcohol involvement was a significant factor, accounting for 45 fatal crashes (33% of all fatal crashes) and 48 fatalities. Alcohol-related crashes also included 379 injury crashes and 483 PDO crashes. Motorcycles were involved in 322 crashes, resulting in 31 fatalities and 225 injuries. Pedestrian crashes totaled 94, with 3 fatalities, while bicyclist crashes numbered 83 with no fatalities. The report highlights distinct demographic and environmental trends. Drivers aged 14–20 were involved in 15 fatal crashes, 892 injury crashes, and 2,521 PDO crashes. Male drivers were disproportionately represented in fatal crashes, accounting for 147 of the 189 drivers involved. Environmental data indicated that the majority of crashes occurred on dry asphalt surfaces during clear weather and daylight hours. However, winter conditions contributed significantly to severe crashes, with ice/frost and snow accounting for 21 and 5 fatal crashes, respectively. Seat belt usage data showed high compliance, with over 80% of drivers and passengers in most counties utilizing safety equipment. The findings underscore the persistent impact of alcohol impairment and the specific risks associated with young drivers and motorcycle operation, providing a baseline for targeted safety interventions.

Key finding

Wyoming recorded 14,653 traffic crashes in 2010, resulting in 137 fatalities, 4,462 injuries, and $3.48 billion in economic losses, with alcohol involvement accounting for 12% of all crashes.
