[Tagging] Signal-controlled roundabouts

[Volker Schmidt]

No. One of the characteristics of a roundabout is that you have precedence
when you are in it. In this case there is a main road that has precedence
over the two minor roads.
If you want to turn left (looking in the direction of the photo) you have
to yield to oncoming traffic coming from the opposite direction.
This is a main road crossing a minor road with an island (or short piece of
dual carriageway) in the middle of the junction
