2006 ANNUAL REPORT OF THE CALIFORNIA DUI MANAGEMENT INFORMATION SYSTEMIn this fifteenth annual legislatively mandated report, 2003 and 2004 DUI data from diverse sources were compiled and cross-referenced for the purpose of developing a single comprehensive DUI data reference and monitoring system. This report presents crosstabulated information on DUI arrests, convictions, court sanctions, administrative actions and alcohol-involved crashes. In addition, this report provides 1-year proportions of DUI recidivism and crash rates for first and second DUI offenders arrested in each year over a time period of fourteen years. Also, the long- term recidivism curves of the cumulative proportions of DUI reoffenses are shown for all DUI offenders arrested in 1994. Analyses were conducted on the effectiveness of alcohol education programs upon the 1-year postconviction records of those convicted of the reduced charge of alcohol-related reckless driving, and on the effectiveness of the 3-month versus 6-month alcohol education programs on the 1-year postconviction records of first offenders. Two additional subanalyses were conducted to determine if differences on the outcome measures were related to BAC level (below .20 and .20 and above). The proportions of 2003 convicted first and second offenders who completed their alcohol education/treatment program requirement are also presented. |
