If we encounter a broken-down vehicle on the roadway, is it correct to overtake it by crossing the solid line?

A)Yes.Correct
B)No.
Although overtaking is prohibited, you may invade the part reserved for the opposite direction in order to:
- Overtake slow and vulnerable users (cycles, mopeds, pedestrians, animals, and animal-drawn vehicles), when their speed allows the manoeuvre to be performed without risk.
- Pass obstacles or immobilised vehicles (broken-down, in an accident, etc.), after making sure there is no danger (if the reason for the immobilisation is imposed by traffic conditions, you may not pass it and must stay behind it).
The lateral separation must not be less than 1.5 metres.
Therefore, it is correct to overtake the broken-down vehicle.
