I don't know a lot about the van side of panther, but in my straight and tractors they do pay more for team and hazmat, it is figured into the contract rate for the truck. They also pay extra for Canadian clearance.
Hey Underdog, I think you might be mistaken about the Hazmat for vans. A van at Panther does not placard as it also does not carry over the limit (1001 pound ?) of hazardous materials. Also, Panther does not pay more per mile for teams, they just allow you to run more hours which means more money.
Two years ago when Panther reduce the 77 cents per mile to 70 cents per mile they had program that 3 cents more for hazmat and 3 cents more for team. And yes they are some loads even if they are less then 1000 pound and require hazmat.
