What must you heed in this situation?

In the situation depicted, you are approaching a bus that is stopped at a bus stop with passengers boarding or alighting. According to German traffic regulations, the correct actions when passing such a bus are important for ensuring the safety of passengers.

You must adhere to two key rules:

1. Pass the bus at walking speed: This allows for better control and reduces the risk of accidents with pedestrians who might suddenly step out from behind the bus.

2. Pass only if you are sure passengers are not endangered: It's crucial to ensure that no passengers are in a vulnerable position as you pass the bus. This involves being aware of the surroundings and checking for any pedestrians that might be crossing the road.

Failing to observe these regulations can lead to serious consequences, including accidents and legal repercussions. Always remain vigilant when approaching public transport vehicles, as the safety of passengers should always be a priority.
