The law defines the components and functions of these devices, including remote alcohol monitoring and rolling retests. Courts may impose these requirements alongside other penalties for alcohol-related offenses.
It is a device installed in a vehicle that measures the driver's blood alcohol content and prevents the vehicle from starting if alcohol levels exceed 0.02%.
DUI offenders and individuals convicted under certain alcohol-related statutes may be required by the court to install and operate an ignition interlock device as a condition of their restricted license.
Yes, remote alcohol monitoring devices can be used to confirm alcohol presence and location, especially for unsupervised testing, but ignition interlocks are specifically installed in vehicles.
If a driver fails a rolling retest or refuses to take it, the device will trigger alarms such as horn sounds and flashing lights to alert others and prevent unsafe driving.
