The sign you referred to is the Sidewalk sign, which indicates the presence of a sidewalk or footpath for pedestrians. In Germany, this sign is typically placed at the beginning of a sidewalk and serves to inform drivers that they should be aware of pedestrian traffic.

When you encounter this sign, it indicates that vehicles must give priority to pedestrians using the sidewalk and that pedestrians have a safe space to walk away from traffic. It is essential for drivers to respect this space and be cautious in areas where pedestrians may be present, especially at points where the sidewalk intersects with roadways.

Following this sign's indication promotes safety and helps to ensure that pedestrians can navigate the streets without unnecessary risks. Be mindful of pedestrian rights when you're driving in these areas. If you have any other questions about traffic rules or need further clarification, feel free to ask!
