My dad is a industrial flooring supervisor so he goes out of town a lot on jobs. The whole work crews will jump in vans and trucks to head over to out of state jobs and stay in hotels until it's down. Naturally, at night, after work, they all get hammered and stay up all night. A few years back one of the crews (like 4-5 guys) were coming home in an E250 or 350 on the highway running on hangovers, 2 weeks of hard work, and a total of 3-4 hours of sleep per night. All the passengers were asleep and the driver nodded off. He swerved off the road and clipped the start of a guard rail. The van flipped on it's side and slide and spun down the highway for about 250 yards. All the other crews in the van behind them watched the whole thing. All of them were seriously injured. I think one or two were paralyzed and the driver dyed in the hospital 2 days later. I remember my dad coming home crying about it. They were all young guys in their 20s. I was like 5 or 6.
Driving while drowsy is as dangerous, IF NOT MORE than being under the influence.
