WASHINGTON -- Are you too tired to drive? A new poll finds many answer yes to that question.

ASLEEP AT THE WHEEL Sleep Statistics Vote: Have You Fallen Asleep While Driving?

One in five drivers admits to falling asleep behind the wheel. That figure comes from the National Sleep Foundation, which is trying to get drowsy drivers off the road.

A poll conducted for the foundation found that 20 percent of those asked admitted to falling asleep at the wheel -- and half said that they had driven when they were tired during the last year.

More than one-third of late-shift workers said that they drive drowsy nearly every day.

The poll finds that young men are the most likely to drive when they're sleepy.

The foundation wants the dangers of tired driving covered in drivers' ed classes and on driving tests.

The foundation also says that employers should do more to make sure sleepy workers aren't endangering themselves and others on the road.
