More than 70 percent of teen drivers say they've sent a text while driving.
New technology aims to help parents curb that habit.
It's the latest program to keep teens safer behind the wheel.
Tech expert Mohamed Nasser says parents can download the Drive First App app onto their teens' mobile phones.
It locks a cell phone when a car is moving more than 10 miles per hour.
The app automatically senses the movement and disables the handset from sending or receiving text messages.
