59. Junction layout
A junction layout is a schematic representation of the layout of an upcoming intersection or junction. It can show how roads branch, cross or continue and may help drivers understand which direction to follow before reaching the intersection.
Crossroad-shape diagrams are commonly used on advance direction signs. Depending on the country's sign system, the diagram may also distinguish the main road, side roads, route numbers or destinations.

What can a junction-layout diagram tell you in France?
French supplementary M7 junction-layout panels may clarify the direction of a priority route. The layout must be read with the priority sign to which it is attached.

Does a junction-layout picture itself give priority at a junction in France?
A supplementary diagram helps identify the course of the priority route, but its meaning depends on the accompanying priority sign and local rules. It does not cancel traffic signals or obligations to drive safely.

Should the drawing be treated as an exact map of the junction in France?
No. A schematic diagram can omit islands, turning lanes, cycle facilities and minor road details. Slow down, check the actual road layout, and follow lane arrows, signs and signals when you reach the intersection.
