Incapacitating the DUI Offender: Dealing with the No-car Barrier to Interlocks Robert B. Voas Pacific Institute for Research and Evaluation Calverton, Maryland
Acknowledgements • This, as is the case on most of our work, is the product of a “augmented” PIRE team: • Dr. Paul Marques (PIRE) • Mr. Scott Tippetts (PIRE) • Dr. Dick Roth in New Mexico
Interlocks Are Effective When Installed • Ten studies suggest 50% or more reduction in recidivism. • Lybrand and Bellamy-Cochrane database of systematic reviews—14 studies found RR.36 when installed = 64% reduction.
Ten States of DUI Offenders with Interlocks On and Off Their Vehicles 140% During Interlock 120% After Interlock 100% 80% 60% 40% 20% 0% 1 OH 2 OR 3 NC 4 AB 5 WV 6 MD 7 AB 8 QC 9 IL 10 NM
Original Expectations of DUI Offender’s Acceptance of Interlocks • Interlocks allow offenders to drive when they would otherwise be suspended. • Interlocks allow family members to operate offender’s car. • Interlocks avoid vehicle registration cancellation. • Interlocks avoid family plates.
Despite These Advantages Interlocks Underused • 1.4 million DUI arrests each year in the United States. • 100,000 interlocks in use.
Offenders Resist Interlocks • Usual installation rate is about 10% • Highest rate in a “voluntary” program is about 25% (Quebec, Canada) • Highest rate for a mandatory program is about 40% (New Mexico) • Highest rate achieved by courts 62% when house arrest was alternative (Indiana)
What Happened? • Low risk of apprehension for driving while suspended (DWI) • While sanctions nominally severe, they are frequently not imposed (in Florida only 1/3 convicted). • Limited hardship licenses not requiring interlocks available.
What Happened? • Interlocks are “expensive.” • Interlocks may interfere with drinking. • Interlocks are a nuisance. • Interlocks are embarrassing. • Interlocks require insurance.
Percentage Representation of Court-Order DUI Sanctions (1998)
Ways Interlocks Are Avoided • Delay-avoid installation (California) • No car • Agree not to drive • Install but drive noninterlock car (25% in New Mexico)
Overcoming Offender Resistance • Hamilton County study of 21,325 DUI offenders • Judge required house arrest as alternative to interlock • 62% of the offenders installed interlocks • First DUI recidivism reduced 51% relative to 6 comparison counties • Second offender recidivism reduced 46% relative to 6 surrounding counties
Low-Cost Alternative Needed for No-Car Excuse • House arrest reduces recidivism (Lacey et al.), but costs $10-$12 per day (compared to $2 per day for interlock) and interferes more with normal living. • SCRAM transdermal monitor probably effective, but costs $10 per day (compared to $2 for interlock) and may interfere with normal living.
Full Service Program Needed • Court sentences DUI offenders to “Impaired Driving Control Program” (IDCP). • Provider available who can implement either Interlock or BAC monitoring (SCRAM/electronic home confinement). • Probation officer or provider presents alternatives to offenders who choose one of the options. • No alternative to IDCP except jail.
Full Service Program • Time in program the same whatever the type of control chosen by the offender. • Single price for either option. • Either type of control requires monthly (bimonthly?) visits to provider’s service facility. • Either type of control results in BAC record to the court and treatment provider.
Features of Full Service Program • Provides standardized method for protecting the public applicable to all offenders. • May make mandatory laws effective. • Offenders can choose method of control. • Provides partial record of drinking during the control period. • Can be an important adjunct to DUI/drug courts.
Potential Issues with Full Service Programs • Few interlock providers equipped to provide a Full Service Program. • Pricing of alternative to interlock a problem. • SCRAM is generally in use for only short periods (2-3 months). • Will integrating the more expensive alternatives to the interlock effect the period that judges will sentence offenders to Full Service Program?
Public Acceptance • Punishment fits the crime. • Minimum interference with daily living. • Fair: Equally applicable to all offenders. • Offender pays. • Can be a support to DUI/drug court programs. • Limiting drinking can support recovery for individuals with alcohol use disorders.
