“…These vehicles have large low-pressure tyres, seats designed to be straddled, handlebars for steering, and motorcycle-type engines (Rodgers and Prowpit, 2001). Concerns about the safety of ATVs have risen over the past two decades following the growing number of ATV injuries and fatalities (Axelband et al, 2007;Hall et al, 2009;Helmkamp, 2001;Helmkamp et al, 2008a;Hendricks et al, 2006;Moore, 2008;Rodgers and Prowpit, 2001). In New Zealand, the Department of Labour has identified the estimated 70,000 ATVs in use in New Zealand as a major safety concern associated with an average of seven deaths per year, and costs to ACC (Accident Compensation Corporation (ACC), New Zealand's national no-fault insurer) totaling over NZ$ 3.5 million per year (Moore, 2008).…”
