Pedestrian priority intersections
Introduction
The give way sign is a traffic sign that is used at intersections or conflict zones in the transportation infrastructure that indicates to the driver, in the event that he or she is unable to cross or merge safely without interfering with the maneuver of the vehicles of the other stream, the obligation to give way. This signal is frequently used at expressway entrances (highways) or at level intersections with priority control. It is also common to see these signs at the entrances to roundabouts to give priority to the ring road.
Priority of passage
The obligation to give way may not be the case and said incorporation may be carried out from a highway and this road at its corresponding intersection. Being the vehicles that are traveling on the highway or highway, they will always have right of way over those that are going to join it. Even if they are using the last sections of an acceleration lane, they must stop if necessary before merging to avoid dangerous situations and the safety of other drivers.
Being another way, that the vehicles that circulate on the preferred route (in this case being a highway or highway) must - to the extent possible and as long as it does not entail any risk for other road users - facilitate the incorporation of the vehicles, changing if possible.
In Europe, a yellow diamond is used that fulfills the opposite function of the give way (or stop) and is to give priority to the road that has this sign. When this sign does not exist in an access, the driver must proceed with caution, similar to how he would do with a yield sign.
Shapes
The yield sign can be presented in two ways:
• - Vertical sign: It consists of a board with a white triangle with an inverted red border, usually made of reflective material on a metal stem.
• -

Horizontal mark: The mark is a triangle with the vertex opposite the shorter side, directed on the road with the vertex towards the side of the approaching vehicle.
