A queue in British English refers to a line, usually of people, cars etc., assembled in the order they arrived and waiting for some event or service. The next person to be served is the person at the front of the queue. New arrivals go to the back of the queue. As people are served, they move forwards in the queue, until they reach the front and are served, thereby assuring that people are served in the order they arrived.
