That appears to be the case: https://en.wikipedia.org/wiki/Commercial_driver‘s_license
“Employers, training facilities, states, governmental departments, and private institutions may be permitted to administer knowledge and driving test for the state. The test must be the same as those given by the state issuing the CDL, and the instructors must meet the same professional certification as state instructors.”
Egad!
A window wide enough to drive a truck through. Wow. TokarevM57's post really highlights the hazard-how many of these people are carrying hazardous cargoes without the prerequisite knowledge to do it safely, never mind just being able to follow road signs and observe the rules of the road. States that have allowed this should be penalized severely by the Federal government for making this loophole easily available for illegals. We know that is what they did.
It is shameful-utterly shameful that we have allowed the wages of American truckers to be depressed in order to get illegals at lower wages on the road. Both parties are complicit, but again, as with nearly everything Trump has done, he has done something about it instead of kicking it down the road or looking away.
We will never see another President in our lifetimes like Trump.
