The "Toilet" sign, often depicted by the symbol of a toilet, indicates the presence of restroom facilities nearby. In the context of German traffic, this sign is used in places where public convenience is available for drivers and passengers. It signifies that you can find clean and accessible restrooms, which is particularly useful on longer journeys or when traveling in areas with fewer services.

If you have further questions about traffic rules or need information on other signs, feel free to ask!
