What must you show passengers if requested in regular traffic?

You answered correctly. As a driver in regular public transport, you are required to show passengers the transport rates, transport conditions, and the timetable if they request it. These documents ensure transparency and inform passengers about prices, conditions, and schedules. A city map with a road register is not mandatory to show passengers. In summary, always have the fare information and timetable available for passengers upon request, as this is regulated in German transportation rules.
