Put Simply, Guardian aims to reduce repeat offenses by drunken drivers.

To date, the Guardian Ignition Interlock devices have already prevented 4,931,988 intoxicated drivers from accessing the roadways.

These in–car devices incorporate intelligent driver recognition, mandatory breath–testing before ignition and immediate lock–down of vehicle's ignition system at the first indication of alcohol, to successfully prohibit intoxicated drivers from repeatedly harming themselves and their fellow citizens.

Studies show that re–arrest rates have decreased by 66% among individuals who have used Guardian’s Interlock device.
