Falling Asleep while Driving

This is scary. According to a study by the CDC, there are a lot of drowsy drivers on the road--and admittedly so. Fully 4.2% of Americans aged 18 or older say they have fallen asleep while driving in the past 30 days. By state, drivers in Texas are most likely to fall asleep at the wheel, with 6.1 percent doing so in the past month.
