Where:
On any road, but most commonly in mountainous, hilly, or winding areas where visibility may be limited and sharp curves are present.
The chevrons are positioned along the outer edge of the curve to provide a visual guide through the turn.

Purpose:
To warn drivers that the road ahead turns sharply, either to the left or to the right.
These chevrons help prevent accidents by alerting drivers to adjust their speed and positioning in anticipation of the sudden change in direction.
They are particularly useful at night, during poor weather conditions, or on roads with blind curves.

Action:
Reduce your speed well before entering the curve to maintain full control of your vehicle.
Position your vehicle correctly within your lane and follow the chevrons as a guide through the bend.
Be prepared to brake gently if needed, and ensure you can stop safely within the visible distance ahead. Avoid overtaking or making sudden maneuvers on or near the curve, and maintain a safe distance from vehicles in front of you, as stopping distances increase on sharp turns.
