The objective of this study was to analyze workers' compensation injury and fatality data associated with the occupational use of all-terrain vehicles (ATVs) in Montana. Data were provided by the Montana Department of Labor and Industry Workers' Compensation Injury and Occupational Disease Database. Claims were identified based on a search of injury codes related to vehicular claims and then narrowed by a keyword search for events related to ATVs. Two hundred and fifteen ATV-related claims were identified between 2007 and 2012. The majority of claimants were identified as male (85%), with 23% of total claims between the ages 20-29 at the time of injury. The agriculture industry accounted for 59% of all claims. The results of this investigation indicated that the cost of occupational ATV injuries and deaths during the study period totaled nearly $2,600,000. The agriculture industry is disproportionally represented in ATV workers' compensation claims in Montana. Characterizing and understanding the risk factors associated with occupational-related ATV injuries is critical for developing strategies and programs aimed at injury prevention. Evaluating the gaps in data acquisition and reporting could aid in ensuring comprehensive and complete future investigations of ATV incidents.
