Aren't we talking team driving here? If you are team driving and one drives 10 hours and the other drives 10 hours, then the truck is moving 20 hours a day. You can easily drive 1000 miles a day team driving...I would assume. And that would not be illegal.
When I was with Werner, no body I talked to made what Werner promised. As solo driver I got more miles than most but the last week of every month they made me sit a lot, so it would keep short of the mileage bonus. The positive side of teaming for Werner is that most loads a drop and hook loads. Solo drivers generally pick up loads and drop them in a drop lot for team trucks to haul.
