From Jason Walker, COO, United Road Services:

When United Road first began going down the road with NVTA, we knew we wanted to give as much of a discount on fuel to our small and mid-sized carriers as United Road itself gets. So, we reached out to our vendors to see what they could offer.

Our fuel vendors were only willing to allow us to pass down our full discount if the carriers were directly related to United Road. So we needed to find a way to align the NVTA carriers with United Road. The solution was to have the funds on the fuel card come directly from United Road. In other words, whenever a carrier hauls for us, their payment goes directly onto that card. 

However, the card can be used for any purpose whatsoever once it's loaded, or you can transfer money off into your personal account for a small administrative fee (which goes to the card vendor, not to United Road).
