A bill to crack down on drunken driving in the Volunteer State is now headed to Tennessee Governor Bill Haslam.
The bill, sponsored by Kingsport State Representative Tony Shipley, requires interlock devices to be installed in the vehicles of all drunk drivers who have been convicted with a blood alcohol rate of .08 or higher.
The devices are small pieces of equipment attached to the steering wheel of a car with a tube the driver must breathe into before the ignition will start. According to the Centers for Disease Control and Prevention, the devices have been proven effective in reducing drunk driving recidivism by 67 percent.
If signed by Governor Haslam, Tennessee will become the 18th state with the requirement.
