A new study indicates that laws against texting while driving actually cut down on traffic deaths. The study, published in the American Journal of Public Health, examined traffic fatalities for states with and without laws banning texting-while-driving over 2000-2010. The evidence showed that texting bans were associated with a three percent drop in overall traffic fatalities. In addition, the study showed that states that only banned young drivers saw an 11 percent decrease in deaths among that group.
