More than 100 people gathered at the Statehouse Wednesday as the governor ceremonially signed into law a measure known as "Emma's Law." The new law requires more people convicted of DUI to install a device that won't let their vehicles start unless the driver passes a Breathalyzer test.

It's named after 6-year-old Emma Longstreet... a Lexington girl killed by a drunk driver in 2012. Her father David Longstreet spent the past two years lobbying for the change.

Haley said she hoped the law would help prevent repeated DUI offenders.

 

The new law will require that the device be hooked up to a car’s ignition for all first-offense drunken drivers who plead guilty or are convicted and have a blood alcohol content of .15 or higher. The driver must pass a blood alcohol test to start the car.
