Really? Canadian trucks are subject to all that; why wouldn't the Mexican trucks?
Don't confuse allowing their trucks to operate in the U.S. with allowing their poor people to move here illegally.
So Cal is already floating in mexican truck drivers and it ain't pretty.
At one point they were trying to set up their own, independent, union. I don't know what became of that but it seems to have gone away.
I'd hope that is why DiFi went against ideology to oppose this program.
On the other hand, if she's pushing for US trucks operating in mexico, expect your insurance costs to skyrocket.
