A vehicle-control system suitable for use on an automated vehicle includes a human-machine-interface and a controller. The human-machine-interface accepts an input from an operator of a host-vehicle. The controller is in communication with the human-machine-interface. The operator inputs a notification to the human-machine-interface. The notification indicates that the operator detects a circumstance that suggests a presence of the emergency-vehicle on the roadway that has not been detected by the system. The controller drives the host-vehicle in accordance with rules governing an operation of vehicles proximate to an emergency-vehicle stopped alongside a roadway.
