For the doctrine of vicarious liability to apply, the plaintiff must prove all the typical elements of a tort with respect to the driver’s conduct—duty, breach, causation, and harm—and then also prove that the driver was acting in the scope of their employment. A driver who is driving for work is driving within the scope of their employment unless they were engaged in some major detour. For example, if a pizza delivery driver is on their way to deliver a pizza when they get into an accident, then there is likely vicarious liability and the pizza restaurant may be liable. But if the delivery driver delivers the pizza and then decides to not return to work but instead drives their girlfriend around town, then an accident occurring during this detour may not give rise to vicarious liability.
