Driver picked up Friend to accompany him on an out-of-town delivery for his employer, Speedy Service. A “No Riders” sign was prominently displayed on the windshield of the truck, and Driver violated specific instructions of his employer by permitting an unauthorized person to ride in the vehicle. While discussing a planned fishing trip with Friend, Driver ran a red light and collided with an automobile driven by Motorist. Both Friend and Motorist were injured. Is Speedy Service liable to either Friend or Motorist for the injuries they sustained? Explain.
