Driver Electronic Device Use in 2007[PDF] Hand-held cell phone use by drivers was up again to 6 percent in 2007 compared to 5 percent in 2006, and this increase in use occurred in many driver categories, including male drivers, female drivers, drivers age 25 to 69, drivers of all races, and drivers in all vehicle types. This result is from the National Occupant Protection Use Survey (NOPUS), which provides the only probability-based observed data on driver electronic device use in the United States. The NOPUS is conducted annually by the National Center for Statistics and Analysis (NCSA) of the National Highway Traffic Safety Administration.
