Every year, teenage drivers are involved in 6,000 to 8,000 car crashes — four times the rate of older drivers. A recent National Teen Driver Survey attempted to find out why. And to get more honest answers, researchers asked thousands of high school students what their friends do while driving. While some 90 percent of teen drivers say they don’t drink and drive, nine out of 10 say they’ve seen passengers distracting the driver, or drivers using cell phones. More than a third say they don’t wear seat belts consistently.
