Evidence shows that these devices are effective while installed on the cars of those who elect to install them. Elective use, however, is still low and, even if installed, recidivism rates climb once the interlock period is completed. To deal with the limitations associated with current interlock programs, a support program for interlock users in Alberta, Canada, has been developed. As part of the requirements for interlock use, the program stipulates that offenders must visit interlock service centers on a regular monthly or bimonthly basis to have their interlock equipment checked and recalibrated. In addition, the program involves educational support, case management, motivational enhancement therapy, and protective planning methods to help offenders avoid the pitfalls of interlock use. Interlock technology is proving its value in reducing the risk drunk offenders pose. Because most offenders view the interlock as a burden and because participation involves some expense, courts should impose relatively severe alternative sentences to motivate drunk offenders to install an interlock. 44 references
