On which journeys are you not allowed to transport persons who are standing up?

Your selection of options is correct because German traffic regulations clearly state that standing passengers are not allowed on certain types of journeys to ensure the safety of all passengers. Specifically, in non-regular traffic and tourist traffic to holiday destinations, the vehicles are often not equipped or designed to safely accommodate standing passengers, which could lead to dangerous situations during abrupt stops or accidents. In contrast, regular traffic typically operates under stricter guidelines that allow for standing passengers under certain conditions, such as designated standing areas. Understanding these regulations helps prevent potential injuries and promotes safe transport practices.
