Do teenage drivers believe talking on a cell phone while driving is less of a risk than texting while driving?
This question was one of several considered by the authors of the paper "Demographic, Driving Experience,
and Psychosocial Predictors of Adolescent Distracted Driving Beliefs." Data from the study could be used to
see if there is support for the claim that the proportion of teens who believe that texting while driving is a
serious or very serious risk is greater than the proportion of teens who believe that talking on a cell phone
is a serious or very serious risk.
