Within a built-up area, what should you note when driving on a road where this traffic sign combination is displayed?

This combination of signs indicates a one-way street (Einbahnstraße) in which cyclists are allowed to travel in both directions.

1. Cyclists may move in your direction even though the street is one-way for other vehicles. This means you must expect oncoming bicycles and drive carefully.

2. When overtaking cyclists, you must maintain a minimum passing distance of 1.5 meters to ensure their safety, as they may be coming towards you or moving along the road.

The third option about cyclists using footpaths is incorrect because here cyclists are explicitly allowed on the roadway in both directions, so they are not required to use footpaths.

Understanding these signs helps you anticipate bicycle traffic correctly and follow the safety rules for passing cyclists in a one-way street.
