Who’s got the lead here – how’s it going?

Hello @ all, I have a road situation at the bottom of the picture where I never know exactly who has the driveway – who can answer me the following question. The road that turns to the right, at the latest from where the middle lines start, two-lane. If I am now on the (one-lane) track … may I drive first on the “new” left lane or have cars that drive directly from the straight lane to the “new” left lane of the turning road the driveway?
