It is odd that they mention several plausible reasons for the problems they see but really seem to single out immigration as the key problem. That seems backwards to me. If safety regulations are no longer being enforced as they claim, where the drivers were born is irrelevant.

You can't effectively teach safety regulations to foreign truck drivers if they don't speak a word of English.

Sure but that still gets back to training drivers and enforcing regulations as the core issue. We don’t allow people who can’t pass proper medical training to be doctors no matter how many undocumented people may apply.
