Likewise, house arrest keeps an individual in the community, providing little interference with daily living. The alcohol safety interlock system forces individuals convicted of DWI to model behavior that does not include drinking and driving. Likewise, the presence of the alcohol safety interlock in an offender's vehicle is a constant reminder from the court that drinking and driving do not mix. Additionally, safety measures have been installed to prevent another individual from blowing into the device for the driver. The interlock is not the panacea, however.
Statistics show that while the interlock is in place, there is less drinking and driving behavior.
Once the interlock has been removed, there is some evidence that the chronic drunk driver's previous behavior may return. Thus, the time period that the interlock is in place offers a window of opportunity for treatment and remediation to occur so that drinking and driving behaviors can be more permanently eliminated. A number of speakers concurred that the alcohol safety interlock has not experienced wide use by judiciary systems. A partial reason for this, noted the experts, is because an optimal managerial system has not been established and replicated. Some experts say that the system should be managed by the courts because its use is intimately tied to probation and other sentencing procedures.
