Mothers Against Drunk Driving are backing a bill that would strengthen Tennessee's drunk driving laws.
The plan would force convicted DUI offenders to have interlock systems installed in their cars. The device requires a driver to blow into a breathalyzer. If you're over the limit, the car won't start.
According to MADD, 50 to 75 percent of convicted drunk drivers will keep driving on a suspended license.
In 2011, nearly 10,000 people across the US died in wrecks that involved alcohol.
