What is the meaning of the following road marking?

- Warning, road works.
- Slow down! Rough road ahead.
- Parking zone for private passenger cars.
- Correct answer: A stopping place for certain types of vehicles where lay-bys are absent.
Why this is the answer
The correct answer in the official bank: A stopping place for certain types of vehicles where lay-bys are absent.
A yellow zigzag marking along the edge of the road designates a stopping place for a certain type of vehicle, where there is no lay-by. So it is not a parking zone for private passenger cars, and it is not a warning about a rough road or road works.
