Requiring DUI offenders to install an interlock to reinstate: Effective?

描述（由申请人提供）：车辆酒精联锁系统似乎提供了一种有用的技术来减少醉酒驾驶（DWI）违反者的再犯。如果驾驶员的血液酒精浓度（BAC）为。03或更高。一组广泛的研究表明，如果将联锁装置安装在酒后驾车违法者的车辆上，其减少再犯的效率约为65%。然而，当他们可以选择在一段时间内安装联锁系统，否则他们将被完全暂停，只有大约十分之一的DWI违法者利用这个机会合法驾驶联锁系统。为了增加违法者安装联锁装置的动机，一些州将其作为恢复驾驶执照的一项要求，这样未能安装联锁装置就会成为合法驾驶的永久障碍。这项申请要求资金扩大对82000多名酒后驾车罪犯的初步研究，这些人在新法律生效后被定罪，并被判处佛罗里达州联锁计划，这是第一批采用这一程序的人。我们的初步研究表明，将联锁作为恢复的先决条件似乎会增加参与率，但会延迟计划的实施。R21申请中提出的研究将收集佛罗里达州法律出台前的数据，以确定相对于没有这样的法律，要求恢复联锁是否会延迟所有酒后驾车违法者的恢复，使用者和非使用者，以及它是否会减少全州范围内的酒后驾车累犯率。

DESCRIPTION (provided by applicant): Vehicle alcohol interlock systems appear to provide a useful technology for reducing the recidivism of suspended driving-while-intoxicated (DWI) offenders. These devices prevent the starting of the vehicle if the driver has a blood alcohol concentration (BAC) of .03 or higher. An extensive set of studies has demonstrated that interlocks are approximately 65% effective in reducing recidivism when installed on the vehicle of otherwise fully suspended DWI offenders. However, when given the option to install the interlock during a period when they would otherwise be fully suspended, only about 1 in 10 DWI offenders takes advantage of the opportunity to drive legally with the interlock. To increase offender motivation to install an interlock, some states are making it a requirement for reinstatement of the driver's license so that failure to install becomes a permanent barrier to driving legally. This application requests funds to extend a preliminary study of more than 82,000 DWI offenders who were convicted after the new law went into effect and sentenced to the Florida interlock program, which was among the first to adopt this procedure. Our preliminary study has indicated that making the interlock a prerequisite to reinstatement appears to increase the participation rate but delays implementation of the program. The study proposed in this R21 application will collect pre-law data in Florida to determine whether relative to the absence of such a law, requiring an interlock for reinstatement delays the reinstatement of all DWI offenders, users and nonusers, and whether it reduces overall statewide DWI recidivism. PUBLIC HEALTH RELEVANCE: Typically offered as an option for driving during part of the license suspension period, alcohol ignition interlocks have been shown to reduce the risk to the public of injury in a highway crash by substantially reducing the frequency of impaired driving by DWI offenders. This study will determine whether a new approach to interlocks-requiring DWI offenders to install them as a condition of driver's license reinstatement enhances the public health benefits of interlocks by increasing the number of offenders who install them and producing greater reductions in recidivism.
