Rudisill TM, et al. - Among adult drivers of different ages (19-24, 25-39, 40-59,≥60 years), sex, race/ethnicity (white non-Hispanic, black non-Hispanic, Hispanic, Other) or rurality (urban, rural), researchers ascertained if legislation that limits cellphone use while driving was correlated with lower self-reported hand-held cellphone conversations or texting behaviors. In this cross-sectional study, participants were 9,706 individuals ≥19 years of age who indicated they were a current driver and partook in the 2011-2014 Traffic Safety Culture Index Surveys. Findings suggested an association of universal hand-held calling bans with lower self-reported cellphone conversations for adult drivers. In order to reduce texting while driving, more interventional work may be needed to target adult drivers.
