Texting and driving may be against the law in many places, but new numbers reveal that's doing little to deter it.

Researchers with the Centers for Disease Control say one out of three Americans text or email while driving. Almost 70 percent of people talk on their cell phone while behind the wheel.

Of these groups, there were few differences between the sexes in cell phone use while driving, but when broken down by age the biggest offenders were in the younger age brackets. Men and women aged 25-44 reported talking on their phones while driving more than those between 55-64, while those 18-34 text more often than older demographics.

The CDC says distracted driving is becoming a bigger factor in traffic crashes. Colorado is one of several states to ban texting and driving.
