Understand That I Have a Jaundiced View
I used to work the aptly named graveyard shift in the ER at a community hospital along I-95. I saw the results of people trying to push driving into the night beyond their limits on many occasions. But just as importantly, because I was used to being up in the middle of the night and sleeping during the day, I would often start my own RoadTrips late in the evening and drive through the first night. I could always tell when the bars closed (1:00 or 2:00 AM depending on the state) and when drivers were hitting their wall (usually somewhere in the 3:00 to 4:00 AM range) by the amount of weaving that the cars around me were doing. But there was a distinct difference. Drunks would tend to weave back and forth trying to follow a road which was wavering in their vision. Tired drivers would simply start wandering off the road in one direction until they ran over the rumble strips and woke up, or hit a guard rail or something less forgiving. And yes I have witnessed two fatal accidents involving drivers with no apparent alcohol or drug influence who simply ran off the road in the wee hours. If you are not used to being awake at those hours, trusting your life, and that of your child, to decisions made and reflexes tested when you are sleep deprived ranks very, very near the bottom of my recommendations.
