You want to turn left and the lights are "green". On your left there is a tram wanting to proceed straight ahead. What is correct?

When turning left at a green light in Germany, you must give way to oncoming traffic, including trams coming from behind or alongside you on the left and wanting to go straight. Even though you have a green light and so does the tram, trams going straight have priority over vehicles turning left, unless traffic signs or signals state otherwise. That’s why answer 1 ("You must wait") is correct: you have to let the tram pass first before turning left. This rule helps avoid collisions and ensures smooth traffic flow at intersections with trams.
