Taxi-driver applicants must be 'of good character', meeting strict requirements regarding any criminal record, then first pass a written test which qualifies them to make an "appearance". At appearances, Knowledge boys and girls must, without looking at a map, identify the two points of interest in metropolitan London that their examiner chooses and then choose the shortest and most sensible route from one to the other. For each route, the applicants must recite the names of the roads used, when they cross junctions, use roundabouts, make turns, and what is 'alongside' them at each point.
