🚦 # Diagram 520 – Dual Carriageway Ends Ahead # ⚠️🛣️

A Diagram 520 Dual Carriageway Ends Ahead sign is a crucial UK road safety sign, warning motorists that they are approaching the end of a dual carriageway, where the road will transition into a single carriageway. This sign ensures that drivers reduce speed, prepare for oncoming traffic, and adjust to potential road narrowing.

This sign is commonly placed before the transition from dual to single carriageways, on highways, and near major junctions, ensuring drivers anticipate the road layout change.
