Worth noting that America does not have an official language. Trump tried to declare one via an executive order last year, which is likely not legal, like most of his executive orders. I think imposing an English test is a bit arbitrary and not inline with the culture of America, which is to be a welcoming melting pot.
That said, unrelated to language, it does seem like there is a lot of fraud in the testing and licensing of commercial drivers. I’ve seen videos where investigations showed a sophisticated scheme of fake testers filling in for the actual driver.
