This study explores the effectiveness of ignition interlock devices in reducing recidivism among those convicted of drunk driving in Hamilton County, Ohio.
Abstract
The study examines both the short- and long-term effects of ignition interlock devices versus license suspension on recidivism of convicted drunk drivers. Persons selected for the study included all first time offenders who had a blood alcohol content of .20 percent or higher when arrested, persons with prior convictions for drunk driving in the previous ten years, and those who refused to submit to a breathalyzer at the time of their arrest. With the ignition interlock devices, offenders frequently claimed they had difficulty starting their vehicle, even when sober. Problems resulted from faulty interlock devices, problems with the "learned breath code," and sensitivity of the device to other substances. The majority of the problems experienced resulted from difficulties in operating the equipment and not with mechanical defects. Results show that, based on evaluation of the first 30 months of the program, the short term survival rate is significantly increased for those offenders who use the ignition interlock device when compared to those whose licenses are merely suspended. 1 reference
