What does this traffic sign indicate?

This traffic sign indicates a "Park + Ride" facility. In Germany, this means there is a parking area where drivers can leave their cars and then switch to public transportation (such as buses, trams, or trains) to continue their journey. This is designed to reduce traffic congestion in city centers by encouraging people to use public transport after parking their car. Recognizing this sign helps you find convenient places to park your vehicle and avoid driving into crowded urban areas.
