Abstract: This study investigated the effects of a safe driving competition facilitated by publicly-posted individual feedback. The turn-signal use, safety-belt use, and complete intersection stopping of 82 pizza deliverers were observed at two experimental and three control stores, as well as among the civilian population. After baseline observations, pizza deliverers received posted weekly individual feedback on their turn-signal use (at Store A) or complete intersection stops (at Store B). The deliverers' safe driving scores were posted individually on a vertical scale along with their names. Each week the deliverer with the highest average performance was rewarded with a free vehicle-maintenance coupon. Turn-signal use among drivers at Store A (n = 24) increased 22 percentage points from baseline to the intervention phase which was maintained into the withdrawal phase. Complete intersection stopping among drivers at Store B (n = 21) increased 17 percentage points from baseline to the intervention phase and was maintained into the withdrawal phase. Although the winners of the weekly competitions had the greatest increase in performance, non-winners also increased their instances of safe driving during the competition.
