What does this traffic sign indicate?

This traffic sign indicates a "Park and Ride" facility. According to German traffic rules, it marks a car park where drivers can leave their vehicles and then continue their journey using public transportation, like buses or trains. This helps reduce car traffic in city centers by encouraging the use of public transport after parking outside the urban area. The sign is always blue with white and black markings, making it easy to recognize. Knowing this sign helps you find convenient parking options combined with public transit connections.
