Overtaking is prohibited when there is insufficient visibility to carry out the manoeuvre safely, for example:

- Under meteorological or environmental conditions that reduce visibility.
- Behind another vehicle if it blocks our view of the road.
In all these cases, overtaking is permitted if the lanes are clearly separated and the oncoming lane is not crossed.
