Fedex doesn’t own any trucks, only the trailers. They contract with small fleet owners to haul their trailers. The fleet owner would normally be liable, but in an accident this bad, I suspect the victims will go after the deep pockets.
Thanks for that clarification. I was sure they had separate divisions as I used to see drivers dressed in uniforms and others in T-shirts or worse. The guys in uniform always seemed to have the slower less fancy rigs.
