Eyes wide shut. The dangers of sleepy driving

Most Americans are chronically sleep-deprived. However, few people are aware of the extent to which sleep deprivation impairs cognitive functioning. In the United States, at least 56,000 motor vehicle crashes (MVCs) each year, resulting in 1,550 deaths and thousands more nonfatal injuries, are attributed to sleepiness behind the wheel. As lawsuits from fall-asleep MVCs mount, individuals, the transportation industry, public policymakers, and the legal profession are starting to take notice.
