This sign warns that you are approaching a T-junction on a dual carriageway where the central barrier is not continuous. It alerts drivers to a potential change in road layout and the need to be prepared to yield or stop, especially if other traffic is emerging from the side road.

What action should I take when I see the W-020T sign?
