On a change of gradient with no visibility, is it permitted to make a U-turn?

Correct answer

No.

On a change of gradient with no visibility, it is not permitted to make a U-turn. There are several situations in which changing direction is prohibited. One of these is precisely when there is not enough visibility to carry out the manoeuvre safely, as with changes of gradient with reduced visibility, where the layout of the terrain prevents a clear view of what is happening on the road beyond the point where the gradient changes. This measure is intended to prevent accidents, since making a U-turn in these circumstances can be extremely dangerous. Lack of visibility makes it harder for the driver to properly assess the traffic situation in both directions, increasing the risk of head-on collisions or other types of accident.
