Where:
On any public road before reaching a place where another road joins your road from either the left or the right.


Purpose:
To warn that traffic may be approaching or entering your road from the left-hand or right-hand side.
The joining road forms a side junction, and vehicles from that road may either turn into your path or cross your direction of travel.
Because of this, the sign gives you time to reduce your speed and prepare to take appropriate action, especially in areas where side roads are not clearly visible due to bends, trees, or buildings.
It also alerts you that vehicles on the main road may slow down or turn suddenly to enter the side road.
