The sign "Priority over oncoming traffic" indicates that vehicles on the road you are traveling on have the right of way against oncoming traffic. This means that if you encounter vehicles coming from the opposite direction at an intersection or a road that intersects with yours, those vehicles must yield to you.

In practical terms, this sign helps to minimize confusion and potential collisions at intersections where traffic flows meet. It's essential to be aware of such signs as it can profoundly influence right-of-way rules and your driving behavior, ensuring a safe journey. Always look out for any additional guidance or rules at the intersection to ensure safe navigation.
