Secondary Behavior of Drivers on Cell Phones [PDF]

open access: yesTraffic Injury Prevention, 2015
Objectives: The objective of this study was to determine whether cell phone use by drivers leads to changes in the frequency of other types of potentially distracting behavior. There were 2 main questions of interest: (1) As each driver changes cell phone use, does he or she change the amount of driving time spent on other distracting behavior?
