I believe your knowledge of truck driving and over the road transportation is a bit out of date.
Truck drivers and their trucks are HIGHLY regulated.
Check out 49 CFR if you really want to know.
This particular driver was probably either impaired or foolish but it was not lack of regulation that caused this accident.
I am rather surprised to find a There ought to be a law person on this forum.
I’m commenting from what I experience and from what I read. A substantial percentage of accidents and road closings are because a semi was improperly handled. We keep hearing that one reason bridges are in such bad shape is those heavy, speeding trucks. My experience driving is personal. You cannot see around or get around some of those trucks. Surprised a poster would want more regulations? Yes, I want regulations on roads to keep them safe.
