OKLAHOMA CITY (AP) — The mother of a teenager killed in a traffic accident while using a cell phone delivered a tearful plea to legislators Wednesday to approve a bill that would ban texting while driving in Oklahoma.

Gina Harris, whose 19-year-old daughter Brittanie Montgomery was killed in a crash in Oklahoma City in 2006, was among a group of health and safety officials, legislators, teenagers and insurance industry officials who rallied at the Capitol and urged lawmakers to approve the texting ban as a step toward making Oklahoma’s roadways safer.
