NORTH LIBERTY - Almost everyone who owns a cell phone has used it while driving. But put together a teen driver and text messaging and you've got a problem. There is just something so tempting about using the cell phone while driving.

It saves time, sometimes helps make money, but for teenagers, it's all about keeping connected.

"Let's see those hands again, addicted to that cell phone?" said Ron Brady to his driver’s education class full of 14, 15, 16-year-olds who are learning about driving safety.

They learn their quick reaction time is cut short by distractions like a cell phone with text messaging. Every inch that's lost in the reaction time exercise symbolizes brake distance on the highway. And when you add text messaging important eye contact is lost.

"That was the hardest, because you have to concentrate on all the letters on the different buttons are pretty small to try to get it right and you have to worry about spelling and the spaces and everything, it's much harder," said driver’s education student Abi Leveille.

"And you noticed, even after that attempt to have her focus and be aware - you still got the same results," Bandy tell students.

Bandy says cell phones have become part of the teen driving culture. Now he has figure out how to get them to curb it.

"You really have to go beyond saying 'don't do that.' They will keep text messaging even if you say, ‘don't do it'," said Bandy.

Examples like this keep them thinking, especially when they're surrounded by cars where cell phones are the norm. And parents serve as examples.

"No my dad wouldn't allow it."

"My parents have talked to me about it and they have a lot of restrictions - can't use it in the car."

But it's still so tempting. It's hard to concentrate and text, even when you're not driving.

"I swear, if a cell phone was on the railroad tracks and a train was coming and it was ringing - they would answer it," said Bandy.

But Bandy must be getting his message across when you hear gems like this.

"A little distraction can hurt a lot," said one driver’s education student.
