What does this traffic sign indicate?

This traffic sign indicates an auto gas filling station, specifically for LPG (liquefied petroleum gas). In Germany, such signs help drivers identify filling stations that provide alternative fuels like LPG, which is used as an automotive fuel. Recognizing this sign is important for drivers who use LPG-powered vehicles so they can find suitable refueling points. The blue background with the fuel pump symbol and "LPG" inscription clearly marks this type of station. This differs from signs indicating natural gas or hydrogen stations, which have different abbreviations and symbols.
