I don't disagree with that point. People should be able to read, write and speak English before being allowed to drive large trucks all over the place. I'm just saying that speaking English v. reading and writing English and totally different skills and just because one can pass a written driving test doesn't mean that they should automatically be able to speak English as well.
That's much is obvious.
Most of the illegals that I have worked with in restaurant kitchens * are not even able to read their own language.
