Encountering obstacles

There may be all kinds of obstacles on the carriageway, think of dropped loads. There may be work on the road. There may be parked vehicles on the carriageway. Or speed-inhibiting measures may have been taken by the road authority. Speed reducing measures could be flower boxes or narrow passages or something similar.
If an obstacle is on your side of the road, you have to give way to all oncoming traffic, like the stationary rubbish truck in the picture. You have to give way not only to cars, but also to pedestrians, cyclists and mopeds. Of course, if an obstacle is on the other side of the road, oncoming traffic has to give way to you.
Another situation arises when the obstacle is on both sides of the road. This is more difficult to solve in practice. Normally, the person who reaches the obstacle first should be allowed to pass first, but in practice this is not always the case.
