Samenvatting
The percentage of drivers text-messaging or visibly manipulating hand-held devices increased from 1.3 percent in 2011 to 1.5 percent in 2012; however, this was not a statistically significant increase. Driver hand-held cell phone use remained unchanged at 5 percent in 2012. These results are 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 of the National Highway Traffic Safety Administration. (Author/publisher)
