Multiple DUI recidivists pose the greatest threat to the safety of American roadways. A Poisson regression analysis was used to predict the number of self-reported lifetime DUI arrests using a large sample of those arrested for DUI in the state of Florida between January 1, 2007, and September 30, 2008 (N = 25,506). Each individual arrested in the state of Florida for DUI is mandated to complete the driver risk inventory (DRI). The behavioral scales included in the DRI proved important predictors of a number of lifetime DUI arrests. The implications and limitations of the findings are noted.
