Where:
On any road before you reach the point where the road ahead divides into two separate roads forming a "Y" shape.

Purpose:
To warn drivers in advance that the road ahead will split, allowing them time to prepare and choose the correct direction.
The sign helps prevent sudden lane changes or hesitation at the junction, which could lead to confusion or collisions.
It also alerts you to the possibility of vehicles approaching from either of the two roads that branch off ahead.

Action:
Reduce speed and be prepared for the road to divide.
Decide well in advance which of the two roads you need to take according to your route or destination.
Keep to the correct lane for your chosen direction before reaching the junction.
Be alert for other vehicles that may be merging or crossing your path, especially when taking the right-hand branch of the “Y” where visibility or turning angles may be limited.
Maintain full control of your vehicle and signal your intentions clearly to other road users.
