Definition of 531-25

German road sign 531-25, officially designated "Einengungstafel - ohne Gegenverkehr - Einzug links, von 4 auf 2 Fahrstreifen", belongs to the traffic control boards group. It shows how lanes are arranged, shifted, narrowed, separated, or merged, usually before a roadworks or high-speed lane-change area. You may see it in motorways, multilane roads, temporary roadworks, lane closures, lane shifts, merge areas, and construction-stage traffic management, depending on how the road authority has arranged the location. Any left reference should be read as part of the direction, road side, lane arrangement, or placement shown by the sign. The practical meaning is not just the symbol itself, but the driving decision it triggers: adjust speed, position, priority, route choice, stopping behaviour, or attention before the situation becomes urgent. For learners, the key skill is translating the arrows into early lane choice rather than reacting at the last moment. Always combine the sign with road markings, traffic lights, police instructions, and any supplementary plates at the same location.
