Consider Public Safety Issues
Because many convicted DWI offenders whose licenses are suspended or revoked will continue to drive anyway, an ignition interlock requirement may be considered in the interest of public safety to prevent these offenders from driving while impaired and to monitor their driving.

Determine Whether Defendant Is Motivated To Use Device
DWI offenders are not all motivated to comply with interlock restrictions and monitoring requirements. Therefore, an offender’s willingness to comply with these requirements should be carefully explored. Although a properly installed ignition interlock device is extremely difficult to circumvent, an offender who chooses to do so can easily circumvent the court’s order by driving a vehicle that is not equipped with the device.

Discuss Costs
Confirm that the offender can afford the cost of installing and monitoring the device.

Inform The Defendant

  • That use of the device is of benefit to the offender because it will allow the lives of the offender and those of other family members who share use of the offender’s vehicle to remain relatively undisrupted.

  • That installation of the device is a lesser penalty than might be imposed (e.g., impounding the offender’s vehicle) and that stronger penalties will be imposed if the offender fails to comply with the installation and monitoring requirements.

For these reasons, it is in the offender’s best interests to fully comply with the installation and monitoring requirements.
