What is the marked vehicle required to do when the following marking appears on the road?

1. The driver should not cross the separation line, but he is permitted to make a left U-turn.
2. Correct answer: The driver of the marked vehicle should drive on the right of the lines, and he is prohibited from crossing the continuous separation line.
3. The marked vehicle is permitted to cross the unbroken separation line.
4. The marked vehicle should drive on the left side of the unbroken line.
