What is the meaning of the following road marking?

- Correct answer: It marks the line of the road’s edge, where curbstones are absent.
- Driving is prohibited between the yellow lines.
- Parking is allowed on the left side of the line, on a freeway.
- Parking is allowed on the right side of the line, on a freeway.
Why this is the answer
The correct answer in the official bank: It marks the line of the road’s edge, where curbstones are absent.
A continuous yellow line along the side of the road marks the road's edge where there are no curbstones, separating the roadway from the shoulder. Vehicles actually drive in the space between the yellow lines, so it does not prohibit driving there. The line also does not permit parking on a freeway, where stopping and parking are generally forbidden except in an emergency.
