Here is some real good thinkin
So the shoulder lanes are for the bus... but if you are exiting to the right... it is legal to move into the right lane (and you should)
Deal is... who expects a bus to catch you when they are stopping along the way.
My best guess is this guy didn't know the bus was coming up on his right and truck turned from 2nd lane
