Where:
On any road, particularly where the road you are traveling on comes to an end and meets another road at a T-intersection.
These chevrons are usually positioned directly opposite the terminating road to give a clear visual indication of the junction ahead, especially at night or in poor visibility.

Purpose:
To warn drivers that the road ahead does not continue straight but ends at a T-junction where it meets another road running from left to right (or vice versa).
The chevron serves as an additional visual cue to reinforce that you must turn either left or right, as there is no through route ahead.
It helps prevent vehicles from continuing straight and potentially colliding with barriers, embankments, or crossing traffic.

Action:
Reduce your speed well before reaching the end of the road and be prepared to stop or yield as required.
Look carefully in both directions for approaching traffic on the intersecting road before making your turn.
Follow the direction signs or road markings to turn safely left or right.
Exercise extra caution in poor lighting or adverse weather conditions where the junction or approaching traffic may be harder to see.
The T-Junction Chevron is often displayed together with a T-Junction Warning Sign placed some distance before the intersection to give advance notice of the upcoming road termination.
