NASHVILLE, Tenn. -

Tennessee Governor Bill Haslam has signed a bill requiring ignition interlock devices on the cars of drivers convicted of driving under the influence in the Volunteer State.

We've learned the law, sponsored by Tennessee Representative Tony Shipley of Kingsport, now requires first-time offenders to get the device.

By agreeing to the device, DUI offenders will not get a restricted driver's license and will be allowed to drive anywhere.

Representative Shipley says states with similar laws have seen a 30 percent reduction in fatalities due to drunk driving.
