If the roadway is marked with an unbroken separation line accompanied by a dotted line to its left:
- An unbroken line with a dotted line to its left mark a separation area.
- Correct answer: It is forbidden to cross these lines.
- A dotted line may only appear on the right side of a white separation line.
- It is permitted to cross the unbroken line for overtaking only.
Why this is the answer
The correct answer in the official bank: It is forbidden to cross these lines.
An unbroken separation line marks a prohibition on crossing, and the dotted line next to it does not cancel that prohibition. A separation line is meant to separate traffic flows, so it is forbidden to cross the lines. Even for overtaking, there is no permission to cross the unbroken line.
