A hairpin turn is a sharp, U-shaped curve in a road or path, often with a very tight angle, resembling the shape of a hairpin. These turns are typically found on steep hills or mountainous roads and require drivers to reduce speed significantly to navigate them safely. Due to their sharpness, hairpin turns can be challenging to drive through, especially for large vehicles or when visibility is limited. They are designed to help the road wind around a difficult terrain while keeping the road within a manageable route.
