A new study released by the Michigan Supreme Court shows that repeat drunken drivers required to use an ignition interlock system in their cars are less likely to commit another drunk driving offense.
The system requires a driver blow into a breathalyzer-like machine before the car can be started.
The study says just 2.8 percent of those who used the device were repeat violators, compared to 5.5 percent for those who didn’t.
The study examined drunken driving cases in Michigan from 2011-2014.
