The sign "Priority for oncoming traffic" indicates that vehicles approaching from the opposite direction have the right of way. This sign is usually placed in areas where the road narrows, and it is important for drivers to yield to oncoming traffic, making it necessary for them to stop or wait until the way is clear before proceeding.

In practice, when you see this sign, you should be prepared to give way to vehicles coming from the opposite direction. It is essential to be attentive and ensure that you do not obstruct oncoming traffic, particularly in narrow passages or roads without clear markings for lanes. Always pay attention to the road conditions and other signs that may accompany this one.
