-on the standard crossroads with traffic lights (not traffic circle) when driver has green light and go straight or turn right
I note in the above you mention a right turn. Because I had 2 situations one - a crossing where I made a left turn and had green arrow and I had to give way to the tram and oncoming traffic of course.
Then another where I had a left turn but it wasn't a crossing only a left turn over the tracks and a green arrow - oncoming traffic seems to have a red light and I guess trams the same.
Also I've noticed where a car is stopped and has a green arrow to turn right but wants to go straight on. A car will come from the other lane and basically overtake the stationary car to make the right turn. Is this legal? It happens quite a lot.
