The reason why I mention the falling alseep is because many drivers work very odd shifts and if the have a family .. sometimes they down get the sleep that is needed
Another reason I mentioned it is when Loddy mentioned the read was straight as an arrow
Up here .. right before cars get on the bridge from the Jersey side there are a lot of accidents of cars hitting the piller .. many of the times it is because they have fallen asleep at the wheel ...
The buses & cars travel a high speeds .. and if the driver dosed for a second and started to lose control it would be hard for him/her to regain control of such a huge bus
But that is all just a possibility .. we'll hear soon what happen
I have made some long hauls driving cross country, both for work and pleasure, and I have just never allowed myself to continue driving when I feel overwhelmed by sleepiness. I have many times pulled over and catnapped for 15 or 20 minutes at a time to refresh a little. It is just too much of a risk otherwise.
I know that with bus drivers they're on a schedule they have to keep, but if am not mistaken they are under certain restrictions about driving while overly fatigued, much the same as truck drivers are. However, I expect that much like truck drivers, they are subject to cheating and pushing the limits in many cases.
