Samenvatting
Since 2007, many states passed laws prohibiting text messaging while driving. Using vehicular fatality data from across the United States and standard difference-in-differences techniques, bans appear moderately successful at reducing single-vehicle, single-occupant accidents if bans are universally applied and enforced as a primary offense. Bans enforced as secondary offenses, however, have at best no effect on accidents. Any reduction in accidents following texting bans is short-lived, however, with accidents returning to near former levels within a few months. This is suggestive of drivers reacting to the announcement of the legislation only to return to old habits shortly afterward. (Author/publisher
