ScienceDaily (Oct. 22, 2012) — All-terrain vehicle (ATV) manufacturer warning labels aimed at children under age 16 are largely ineffective, and formal dealer-sponsored training is infrequently offered and deemed unnecessary by most young ATV users, according to new research presented at the Oct. 22 at the American Academy of Pediatrics (AAP) National Conference and Exhibition in New Orleans. The study of ATV crashes involving children also found less than 35 percent of children were wearing a helmet when injured in an ATV crash, and nearly 60 percent were riding again within six months.
