HICKSVILLE - A new federal study reveals teens have taken up a new vice.

In a new report from the Centers for Disease Control and Prevention, more than 40 percent of teens who drive admit to texting while behind the wheel.

Robert Sinclair of AAA says car crashes are the number one cause of death for teenagers. Sinclair added distractions, including texting while driving, are estimated to cause a quarter to a third of all fatal accidents.

The report also found teens are smoking less, having less sex and fighting less often at school.
