German road sign 542-15, officially designated "Aufweitungstafel - mit Gegenverkehr - 2-streifig plus Fahrstreifen links und 3 Fahrstreifen in Gegenrichtung", belongs to the traffic control boards group.

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.

Always combine the sign with road markings, traffic lights, police instructions, and any supplementary plates at the same location.

Sign 542-15 is a lane widening board that informs drivers about upcoming changes in lane configuration, specifically indicating that your direction has fewer lanes ahead compared to oncoming traffic. Its primary purpose is to prompt early driver action to select the correct lane before reaching the merge or lane-ending point.
This description means that in your direction of travel, the road ahead will effectively have 2 lanes plus an additional lane on the left (making it seem like 3 lanes for you), but crucially, the opposing traffic will have 3 lanes. This implies a complex merge or shift where your path narrows relative to the oncoming flow, requiring careful attention.
When you see sign 542-15, you should reduce your speed, scan the road ahead to understand the lane layout shown by the arrows, and choose your correct lane as early as possible. Always follow any temporary markings or barriers and maintain a safe following distance, as other drivers might react differently to the changing road layout.
A common trap is reacting too late to the lane change or merge indicated by the sign. Learners might assume their lane continues when it actually ends or merges. It's crucial to understand that the sign is a warning and requires proactive lane selection before the controlled section, not a last-minute decision.
Sign 542-15 should always be interpreted in conjunction with accompanying road markings, such as dashed lines indicating lane changes or solid lines showing lane boundaries. These markings visually guide you through the lane configuration shown on the sign, so pay close attention to both.
