How should you behave in this situation?

Your answer is correct because when the traffic light shows green, you are allowed to pass through the intersection without stopping—even if there is a stop sign present. In German traffic rules, the traffic light always takes priority over a stop sign. Therefore, if the light is green, you do not need to stop on the stop line or the line of sight; you can proceed safely. It’s important to remember that stop signs are only mandatory when the traffic light is red or not working. This rule helps ensure smooth and safe traffic flow at intersections.
