They're generally not circumvented to "drive a bunch more hours". That's a fools game. You need to take breaks eventually. Cramming more hours into the work week doesn't actually help you in the long term because the human body can't sustainably run on unsafe amounts of sleep. The books get cooked to avoid wasting valuable on-duty hours while sitting around waiting to be loaded/unloaded. They generally are circumvented to make it to the receiver or next shipper within a given "shift". So instead of stopping 1hr from the receiver you might cook the books, get there, go off duty, sleep, etc. They unload at their convenience before you clock back in and then you cook the books again making it look like you're still off duty when driving an hour to your next load where you repeat the same 2-6hr loading delay shitshow. Then you cook the books a third time running 30min across town to somewhere you can get prepared food and park, hit up the massage parlor, etc, whatever it is you do to burn half a day off duty. So instead of burning a work day doing busy work and sitting in your truck watching movies on an ipad you've accomplished a 34hr reset in that time and most of those 34ish hours were in fact spent off duty.
