New study finds more people driving while dangerously tired

More people are driving while they are dangerously tired, according to a new report from AAA. VOTE: Do you pull over when you're tired? Yes, no or sometimes? The new research from the AAA Foundation for Traffic Safety used in-vehicle dash-cam video from more than 700 crashes and confirmed that drowsy driving is way higher than officials think. They say it's difficult to detect drowsiness following a crash and that's why it's one of the most underreported traffic safety issues.
