EDISON - When it comes to teens who have a hard time keeping their hands off their smartphones while behind the wheel, there's an app for that.

The new app, created by a 31-year veteran of the Franklin Lakes Police Department, aims to take the distractions out of driving. Drivers can open the app, called "live2txt," and it will divert texts and calls until it is turned off. The app will also notify parents when their teen turns it on.

The app costs $1.99 and is for sale on Google Play.

A quarter of all teens say they respond to a text at least once every time they drive, according to the Department of Transportation.

In 2011, 3,000 people were killed in distracted driving crashes. Texting made crashing 23 times more likely.
