this is just another reason I love my Chevy. I have extendable tow mirrors that have wide angle lens in the bottom section of the mirror. My truck virtually has zero blind spots from the cab to the back of the trailer. After a few miles you'll know pretty quickly when you're past someone and can change lanes. You'll also find that semi drivers are some of the more alert/helpful drivers out there. They almost always "flash" to let you know when you're past them. More than a few 4 wheelers will flash to let you know also but you can't solely rely on that. Just takes a bit of practice and you'll know when you're past.
