Following the model of Drug Courts, three Georgia Driving-Under-the-Influence (DUI) Courts (established in Chatham, Clarke, and Hall Counties in 2003) were designed to address the underlying alcohol problems of repeat DUI offenders through continuous and frequent judicially supervised treatment, periodic alcohol and other drug testing, the use of graduated sanctions, and other appropriate rehabilitative services. A team comprised of a judge, court personnel, probation officials, and treatment providers met regularly to assess offender progress, and offenders met biweekly with the judge to report their progress. An impact evaluation showed after 4 years of exposure that when the DUI Court graduates were combined with the DUI Court terminated offenders (Intent to Treat Group), the DUI Court offenders had significantly lower recidivism rates:​ 38 percent lower than a Contemporary Group of offenders and 65 percent lower than a Retrospective Group of offenders. The DUI Court Intent to Treat Group had a significantly lower recidivism rate:​ 15 percent compared to 24 percent for a group of matched offenders from three similar counties in Georgia (Contemporary Group) and a 35 percent rate for matched offenders from the same counties as the DUI Court who would have been eligible for the DUI Court had it been in existence (Retrospective Group). Offenders who were terminated from the DUI Courts for various reasons had a recidivism rate of 26 percent. It is estimated that the DUI Courts prevented between 47 and 112 repeat arrests during a four year period due to the reduced recidivism associated with them.
