Monster semis hauling more than one trailer and/or too massive to see or navigate around have made driving unpleasant and more dangerous. They eat up roads. It used to be truck drivers were the best drivers; now there are some total idiots in charge of these things. It does seem that lawmakers, both political parties, have no inclination to regulate them.
I believe your knowledge of truck driving and over the road transportation is a bit out of date.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.
