What the Dual-carriageway ends ahead sign means
The divided road (dual carriageway) is ending ahead. The two separated roadways come back together into a single two-way road.
What you must do
Slow down and prepare to merge if needed. Once the dual roadway ends you may meet oncoming traffic, so keep left, do not overtake unless it is clearly safe, and watch for vehicles merging.
