• Interlock Service Center: Person must get interlock serviced every 30 days. • Lockout Mode: If person blows positive for alcohol too many times or misses a rolling test, device may need to be taken to get serviced sooner than 30 days. • Extra time on interlock possible. The interlock service center may report any violations, too many positive blows or missed rolling retests to a monitoring agency which may result in extra time on interlock if the state has a Compliance Based Removal aspect to the interlock law. Many states require oenders to show proof of installation and/or compliance with the interlock order to the court/driver’s license agency in order to have device removed. People who use an interlock are less likely to reoend. Compared to license suspension alone, interlocks reduce repeat oenses by 67% while the device is installed and 39% after the device is removed. Compliance Based Removal could help decrease repeat oenses even more. MADD supports ignition interlocks for ALL arrested drunk drivers. Interlocks accomplish what license suspension and other monitoring technologies do not — separate drinking from driving.
