Distracted driving Research

The problem

The proportion of U.S. drivers witnessed visibly manipulating hand-held devices while driving has doubled since 2010 (NHTSA 2014), despite the fact that 97% of Americans know this is dangerous (AT&T 2012) and texting while driving is illegal in all but four states. Current policies to curb cellphone use while driving have had limited impact because they do not address the underlying impulsivity (Hayashi, 2015) that causes drivers to continue to engage in this behavior despite knowing it is against their best interests (Delgado 2016).
