This publication is based on data from the National Occupant Protection Use Survey (NOPUS) and contained an overview of driver electronic device use in the United States. This publication summarized NOPUS results for the following categories: drivers holding phones to their ears while driving, drivers speaking with visible headsets on while driving, and drivers that were observed manipulating handheld devices while driving.
Results showed that as a whole, the percentage of drivers that were observed holding a cell phone to their ear while driving decreased from 3.8% in 2015 to 3.3% in 2016. In addition, observations of handheld cell phone use continued to be higher among female drivers than male drivers and the percentage of drivers observed speaking and using a headset while driving decreased from 0.6% in 2015 to 0.5% in 2016.
