How to tell if a road in Germany is two-way or two lanes one-way?
Germany uses only white paint for lane markings. In the upper two photos, both the road for one-lane for each direction, and the divided highway with two lanes going in the same direction, the lane markings look the same.
On US roads, white lane markings are used, and yellow is used to signify the left edge of the direction of travel. That is, if the yellow painted line is to your left, you are driving in the right direction. In the bottom two photos of US roads, there is a yellow painted line in the middle of the road, showing that the left lane is for oncoming traffic, and for a divided highway a yellow painted line on far left tells the driver that all lanes travel in the same direction.
So, is there something that indicates if the road has oncoming traffic or is divided?
This comes from my experience a few years ago driving in Germany on unfamiliar roads, at night and in the rain. I turned onto a road, and I wasn’t sure if the left lane was for oncoming traffic or not.
EDIT: Thanks for all the replies. It is as I assumed, about context. The linked photo below shows the entrance onto the B257 that I took one rainy night that made me wonder if this was a divided highway or not. I drove as recommended in the comments: I stayed right until I was sure.
