Where:
On any public road, especially in mountainous, hilly, or rural areas where the road does not follow a straight path but instead twists and turns through the terrain.
These signs are commonly placed before stretches of road where multiple curves occur in quick succession, sometimes with limited visibility due to hills, vegetation, or roadside obstacles.

Purpose:
To warn drivers that the road ahead contains a series of bends or curves that may require frequent steering adjustments.
Unlike a single curve or hairpin bend, a winding road can have multiple curves, left, right, or a combination and these may appear consecutively without additional warning signs.
The sign prepares drivers to maintain constant attention and adjust their speed and position as needed.

Action:
Reduce speed before entering the winding section of the road, allowing for safe negotiation of each curve.
Keep a safe distance from the vehicle in front, as sudden braking or slowing may be required.
Stay alert to changes in road conditions, including sharp bends, narrow lanes, loose gravel, or wet surfaces.
Follow your lane carefully, using smooth and controlled steering movements. Avoid cutting corners, as there may be oncoming traffic around blind bends.
Do not overtake on winding sections, as visibility of the road ahead is limited and unpredictable.
Be prepared for any number of additional curves beyond the first one without further warning, adjusting your speed and vigilance accordingly.
Drive at a speed that allows you to stop safely within the distance you can see, taking extra caution in poor weather or low-light conditions.
