In this US study, state hospitalization data were collected to examine the impact of texting bans on crash-related hospitalizations. Nineteen states were selected for inclusion in this study based on the fact that they met at least 85% of the inclusion criteria, and data from a 96-month period were utilized.
Results showed that, on average, there were 57.3 crash-related hospitalizations per month in the states included in the study. Overall, texting bans were associated with a 7% reduction in crash-related hospitalizations among all age groups. In addition, texting bans were significantly associated with reductions in hospitalizations among persons aged 22 to 64 years and those aged 65 years or older. Sampled hospitals in a state with a primarily enforcement law that explicitly banning texting while driving saw 5.16 fewer motor vehicle collision-related hospitalizations per month. Analyses revealed that approximately 30 crash-related hospitalizations per year were prevented in sampled hospitals following the enactment of a primary texting and driving ban. Based on these results, authors proposed that states that have not passed a primary law in relation to a texting ban should consider doing so.
