However, prohibiting alcohol sales may actually reduce public safety. Research has found that dry counties have higher proportions of alcohol-related traffic crashes than do wet counties. A study of Kentucky suggested that residents of dry counties have to drive farther from their homes to consume alcohol, thus increasing impaired driving exposure. [2] A study of Arkansas noted that wet and dry counties are often adjacent and that alcohol beverage sales outlets are often located immediately across county or even state lines. [3] Other researchers have pointed to the same phenomenon. Winn and Giacopassi observed that residents of wet counties most likely have "shorter distances [to travel] between home and drinking establishments." [4] From their study, Schulte and colleagues concluded that in dry counties "individuals are driving farther under the influence of alcohol, thus increasing their exposure to crashes."
