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

You answered correctly by selecting both answer 1 (in non-regular traffic) and answer 2 (in tourist traffic to holiday destinations). According to German traffic regulations, standing passengers are only permitted in regular bus route services within built-up areas and only if the vehicle is designed for it. In non-regular traffic and in special tourist traffic, it is not allowed to transport standing passengers for safety reasons. So, for non-routine and tourist journeys, all passengers must be seated while the vehicle is in motion. This rule helps ensure the safety of everyone on board and must be followed on these types of trips.
