Thanks for clearing that up for me. I drove for Schneider Transport (STI) and knew a female driver trainer working for Schneider National (SNI) who lived in the States but was training a Canadian driver for a terminal they were setting up in Canada. I caught up with them on the NY Thruway and he was driving as the load originated in Canada going to ME but then they had to pick up a load of paper to deliver in MO so she said she would have to do all the driving as the load wasn’t going back to Canada.
I can see that if it was a Canadian truck with a Canadian driver but he was employed by an American company in an American truck. Just seems a tad nit-picky to me 
Or maybe she was having me on, it’s been done before
