A new study about people's texting and driving habits revealed some troubling results.

The AT&T survey of drivers ages 16 to 65 finds 98 percent of drivers know texting while driving is dangerous, but 75 percent still text anyway. A total of 66 percent read texts at stoplights and 25 percent send texts while driving.

More than a quarter of drivers surveyed say they do it because they believe it is easy to do several things at once, even while driving.

Robert Sinclair, of AAA, says nearly a third of all deadly crashes they've investigated are due to distracted driving involving texting or talking on the phone.

AAA says more than 400,000 motorists each year are injured in distracted driving crashes.

This past weekend, New York state toughened texting laws for young drivers. A first offense draws a 120-day suspension. A repeat offense brings a one-year suspension.
