All terrain vehicles are popular off road vehicles used for a wide variety of work and recreational activities. Recently, the growing popularity of ATVs and the increasing size and power of the vehicles has led to concern over injury risk. The Consumer Product Safety Commission estimates that ATVs result in more than 100,000 emergency department visits annually, including more than 30,000 injuries for children under 16 years. During the past decade, more than 200 children died annually due to injuries sustained on ATVs. Children make up a disproportionate number of ATV injuries.
