What is the role of an "ignition interlock device" in DWI cases in Minnesota?

The ignition interlock device serves a crucial function in DWI cases in Minnesota by preventing a vehicle from starting if the driver’s blood alcohol concentration (BAC) exceeds a predetermined limit. This technology is designed to enhance public safety by ensuring that individuals who have been convicted of driving while intoxicated cannot operate their vehicles while under the influence of alcohol.

By requiring the driver to take a breath test before starting the vehicle, the ignition interlock effectively acts as a safeguard against impaired driving. If the device detects a BAC that is above the set limit, it will disable the ignition system, thereby preventing the vehicle from starting. This measure is part of stricter compliance and accountability protocols aimed at reducing repeat offenses and enhancing road safety.

The other options do not accurately reflect the primary function of an ignition interlock device. While some of those functions, like tracking or providing reminders, may be useful in other contexts, they are not the specific purpose of the ignition interlock device in the realm of DWI prevention.
