It is interesting that you should mention California, because California, back in the 90s, set up the most comprehensive system of inspecting Mexican trucks and to this day say that there is little, if any, safety difference between US and Mexican trucks.
Then that is up to you to prove, a biased remark on your part is not proof. However, I could just as well have said Virginia inspection station.
It's only been a few years since they had to cut back on freeway stops for safety inspections because it was making the already scary traffic even worse. I do have to admit that I got out of the every day freeway crunch in the late eighties but I still see a pot load of mexican trucks and US trucks with mexican drivers when I have to go some distance...and they don't look a whole lot better.
I also have to wonder how come these same trucks are over a hundred miles above San Diego when there is supposed to be a twenty five mile limitation??
