For a disabled kid found abandoned on a street corner in China at age 4, Guo Biao was doing pretty well by last fall. After a decade hidden away in a Chinese orphanage, he had landed at the apple and cherry farm run by Dwayne and Sherri Bowman near Zillah, a farming community in central Washington.Finally. A family. And also a new name: Zeke Bowman. With only a second-grade education, the teen from China was welcomed by the devout Christian family. The Bowmans helped Zeke learn English. For the first time he got a hearing aid for his deformed ear.“He was so thrilled to be here,” Sherri Bowman said.And then last October, Zeke climbed aboard one of the Bowmans’ four all-terrain vehicles, just as he’d done many times before at the end of a day in the orchards. He headed down a two-lane country road called Lucy Lane. For reasons the Bowmans still ponder, he rear-ended a tractor and died that evening in the hospital.ATV tragedies like this – on roads, rather than backcountry trails where ATVs are designed to go – are widespread and have increased in recent years. The latest U.S. figures indicate that ATV crashes kill more than 700 people and injure 100,000 others every year, with nearly two-thirds of the fatal accidents occurring on public or private roads.The accidents keep happening even though all ATVs sold in the U.S. carry a warning label stating that the vehicles are not to be driven on the road. Their high center of gravity and low-pressure tires mean they’re likely to tip over or go out of control on pavement. What’s more, the vehicles aren’t held to federal safety standards for cars and trucks, such as the requirement for seat belts, even though they can reach highway speeds.
