Abstract
An object of the present invention is to provide a task completion confirmation system for vehicles which allows crew members to carry out their tasks correctly by automatically displaying the tasks which have been completed. A garbage truck goes to a plurality of garbage collecting areas to collect garbage. When the garbage truck comes near or reaches the garbage collecting area, a communication device is capable of communicating with a response device in a display plate. It writes into a storage circuit data indicating garbage collecting points, progress of task, and the like, based on the communication. Accordingly, the crew members are able to collect garbage at each of the garbage collecting areas, without making any mistakes.
