What shape is the priority-road sign used in France?

The priority-road sign used in France is a yellow diamond.

The sign indicates that traffic on the marked road has priority at upcoming intersections until a cancellation sign appears. Its yellow center is surrounded by a white border, making it distinct from warning triangles and regulatory circles.

This design belongs to the wider European road-sign system influenced by the Vienna Convention on Road Signs and Signals. Several European countries use a similar diamond to identify a priority road, although border colors and local details can vary.

A common mix-up is confusing this sign with the diamond-shaped priority-road signs used in other countries. The basic meaning is similar, but road users must still follow local markings, traffic lights, and police directions.
