That's why 13 states now have laws against texting while driving and 17 more are considering them. But some experts say what we really need is a federal ban, as CBS News correspondent Kelly Cobiella reports.
The only ting that could prevent one bus driver in San Antonio, Tex. from sending text messages on his phone… was the SUV in front of him. No one was seriously hurt that crash, but the people on a Los Angeles commuter train weren't so lucky.
Twenty-five people were killed in a train collision last fall, including the driver, who was sending text messages moments before the crash.
Russell and Kim Hurd lost their daughter Heather last year. She wasn't texting at the wheel, but a tractor-trailer several cars behind her was. She and another driver were killed instantly in the crash.

"His poor decisions changed my life forever," added Russell Hurd.

Some schools, like one in South Florida, are teaching students the dangers of texting and driving by letting them try it - from the safety of an indoor simulator.
"Even if you take your eyes off the road for two seconds you could drive off the road or hit another car," one student said.
Still, some say that even the hands-on lesson in the dangers of distracted driving may not cause them to put down the phone...
"I think I'm gonna definitely limit it but its hard to say I'm gonna completely stop," said student Sondra Schenker.
That's why the Hurd family is pushing for a federal ban.
"We've learned not to drink and drive 'cause it's against the law," Russell Hurd said. "We are hoping to do the same thing" - so drivers finally get the message to keep their eyes off the screen and on the road.
