To turn left on a road where there is no marking separating the two directions of traffic, where should you position yourself?

A)Mandatorily on the shoulder, to perform the manoeuvre from there.
B)In the centre of the road, invading part of the opposite direction if necessary.
C)Next to the axis of the road, without invading the opposite direction.Correct
When you turn left on a road without a dividing line, you must position yourself next to the central axis of the road, keeping your trajectory within your direction of travel. This position allows you to turn safely without invading the opposite lane, thus avoiding collisions with vehicles travelling in the opposite direction. It is the correct way to perform the manoeuvre while respecting road safety rules.
