This is what happens when you "man up" and drive when you shouldn't. Hopefully the driver is okay. Article says lifeflight was canceled and he elected to go by ground so it might not have been that bad. Or maybe he was still manning up.
Well, he is a log truck driver. There is no "shouldn't," and the phrase "man up" doesn't really apply to some people, since it never crosses their minds that there's an option.
