NBC NATIONAL NEWS — New research shows drunk drivers are less likely to repeat that crime if they are forced to use alcohol interlock devices in their cars.
The Insurance Institute for Highway Safety's study shows the rate of repeat offenders fell by 12 percent in one state.
It happened when that state expanded its interlock requirement to everyone convicted of DUI.
Only fifteen states require interlock devices be installed for a period of time on everyone convicted of drunk driving.
The driver is required to exhale in to the device. If a certain blood alcohol level is detected, the vehicle won't start.
