Philip drove a tractor-trailer rig onto a ferry boat. He left the rig in gear because of a problem with the breaks. Posted regulations prohibited the starting of engines before docking, but when the ferry was about 50 feet from the dock, Philip started his engine. That cause the tractor-trailer to jump forward and strike Herrick’s car, which in turn hit Patton’s car. Patton’s car, at the head of the line, crashed through the ferry’s barricades and plunged into the water. The car could not be recovered. What was the tort duty in this case? Where was the breach of the duty? What were the injuries? What was the proximate cause of the injury to Patton’s car?
