News Summary: Survey on texting while driving: More than half of high school seniors do it

SURVEY SAYS ...: More than half of high school seniors admitted in a government survey that they've texted or emailed while driving.

THE CONCERNS: Distracted driving deaths are most common in teens, blamed for about 16 per cent of teen motor vehicle deaths. Focusing on a cellphone instead of the road leads to delayed reaction times, lane swerves and other lapses with sometimes fatal consequences, experts say.

THE LAW: Thirty-nine states ban texting for all age groups, and an additional five states outlaw it for novice teen drivers.
