National Highway Traffic Safety Administration Electronic Device Use Study

This survey showed that hand-held cell phone use by drivers increased to 6 percent in 2007 compared to 5 percent in 2006. The 2007 rate translates into 1,005,000 vehicles on the road at any given daylight moment being driven by someone using a hand-held phone. It also translates into an estimated 11 percent of vehicles in the typical daylight moment whose driver is using some type of phone, either hand-held or hands-free. This study further showed that hand-held cell phone use continued to be higher among 16- to 24-year-olds and lower among drivers 70 and older. In addition, the use of visible headsets while driving was still less than 1 percent.
