This one device can help keep drunk drivers from doing further harm
About the size of a cell phone, an ignition interlock device is wired into the ignition system of a drunk driver's car. To go anywhere, the driver must blow into the device and register no alcohol on his or her breath. If there's a measurable amount, the car will not start. Does this device work? Yes, and here's how.
