Driving while impaired (DWI) by alcohol and other drugs is a serious public health problem in the United States. In 2006, 13,470 people died in alcohol-impaired driving crashes, accounting for nearly one-third (32%) of all traffic-related deaths.1 Individuals with a first DWI conviction have high rates of recidivism. About 30% of those involved in alcohol-related crashes have a prior DWI arrest or conviction.2-4 These statistics provide impetus for the development of effective DWI offender interventions.
