HealthBeat blog: Sleepy - and dangerous - behind the wheel
In May 2011, a charter bus traveling on Interstate 95 from North Carolina to New York City left the road north of Richmond, Va., at 5 a.m. and rolled over while the passengers inside screamed in fear. Four people died and several others were injured. The driver reportedly had fallen asleep at the wheel. Surviving passengers later told law enforcement officials they saw him gulping down energy drinks and coffee to stay awake.
