ATVs are rapidly growing in popularity, with an increasing number sold every year. They've also become bigger and more powerful-several models now have engine displacement up to 700cc-and capable of extremely high speeds. As a result, ATV accidents have also increased greatly. According to figures from the Consumer Product Safety Commission, there were 113,900 emergency room visits related to ATV use in the United States in 2002, an increase of nearly 68 percent from 1987 when there were 67,800 accidents. In the 20-year period from 1982 to 2002, the CPSC had reports of 5,239 ATV-related deaths.
