Sample definitions involved in the construction of a group of multiple offenders in the Florida Ignition Interlock Program (2008 to 2012) for comparison with the 640 treated offenders. Violations are based on 2 lockouts within 4 hours. Offenders with 3 violations were mandated to attend alcohol use disorder treatment. Propensity analysis was employed to match 806 offenders with 1 or 2 violations with the 640 three-violation treated group.
