German road sign 550, officially 'Zusammenführungstafel - an durchgehender Strecke', is a traffic control board that informs you about upcoming lane arrangements. It visually guides drivers through situations like lane closures, shifts, or merges, commonly found in roadworks or on busy multi-lane roads. You must recognise this sign early, check the arrows for your intended path, and adapt your driving behaviour by adjusting speed and selecting the correct lane before the merge point to ensure a smooth and safe transition.
This explanation of German Road Sign 550, the 'Lane Merge board', is crucial for navigating German traffic safely. Understanding its meaning helps you prepare for lane changes and ensures compliance with traffic rules, essential for your theory test revision.
German road sign 550, officially designated "Zusammenführungstafel - an durchgehender Strecke", 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. An end version marks the point where that specific rule, facility, or marked section ceases to apply. 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.

The exact situation, such as whether it's a lane closure or a shift, will be clearly depicted by the arrows and markings shown.
You will typically encounter sign 550 in areas where traffic lanes are being altered, such as roadworks, construction zones, or on busy motorways and multi-lane roads where lanes are reduced, separated, or merged. It helps manage traffic flow through these temporary or permanent changes.
