The percentage of drivers visibly manipulating hand-held devices has reached 1 percent while the hand-held cell phone use by drivers stood at 6 percent in 2008. This result is from the National Occupant Protection Use Survey (NOPUS), which provides the only nationwide 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. |
