Who’s got the lead here?

Hello, the following situation: InnenStadtdorf, 30 Zone –> Right in front of the left so far clear. So then there is a junction, at which the estuary is already separated (one-way street) and separated by a rain channel (blue strokes) in the ground. What does it look like here? Do I now have to come out of this road (red arrow down) driveway? Or does it apply here as with a sunken curb? I normally leave the one from the right, but I personally have here the “Vorf” often. The picture of the situation is shown in the annex.
