Researchers say putting a cell phone in the hands of young drivers drastically hurts their abilities. A report from the University of Utah says when motorists between 18 and 25 talk on cell phones, they drive like elderly people -- moving and reacting more slowly and increasing their risk of an accident. And the researchers say it doesn't matter whether the phone is hand-held or handsfree. One researcher says a 20-year-old behind the wheel with a cell phone becomes the equivalent of a 70-year-old driver. Researchers have already concluded that motorists who talk on cell phones are more impaired than a drunk driver, putting the equivalent blood-alcohol level in excess of point oh-eight.
