Health officials say more than half of high school seniors admit they text or email while driving.
That's from the first government statistics on how common the dangerous habit is in teens.
An anonymous national survey done last year found that 58 percent of high school seniors said they recently had texted or emailed while driving.
About 43 percent of high school juniors admitted doing the same thing.
The Centers for Disease Control and Prevention released the results Thursday.
The CDC survey did find that teens were being safer on the roads in other ways.
They now wear seatbelts more often and there's less drunk driving.
