You are travelling at a speed of approximately 40 km/h. The lights change from "green" to "amber" when you are 40 m away. What do you do?

In German traffic law, when a traffic light changes from green to amber (yellow), you are generally expected to stop. The exception is if stopping cannot be done safely or you are already so close to the stop line that a safe stop is impossible. At 40 km/h and 40 meters away, you have enough distance to stop safely, so the correct action is to stop. Proceeding would only be allowed if stopping would create a hazard or if you were already right at the stop line when the light turned amber. This rule helps prevent accidents and ensures safe crossing at intersections.
