Uh... have you ever talked to a guy who has worked on Mexican trucks?
I have.
In Mexico, the safety regs we have on our trucks basically don’t exist. Here, your GVW had better be 80,000lbs and under unless you have an over-weight permit and are on the roads designated for over-weight loads.
In Mexico, they load trucks until the frames, tires or axles fail. Then they back off and decide that the load just below component failure is the maximum load of the truck.
Safety inspections? Ha. They don’t need no stinkin’ safety inspections.
Log books? Maximum road time? Log book checks? Pfah. None of that.
The reason why American truckers are superior is that they adhere (in the majority) with state and federal laws.
The rejected plan was a limited, pilot program that required prior certification for all your good stuff. One company - not endless hordes - had managed to qualify.
