之字形弯道, 急转弯
a sharp turn or bend in a road or trail that zigzags in order to manage a steep incline or decline
A switchback is a sharp bend in a road or trail that turns in the opposite direction, often seen on steep terrain or hills. It helps vehicles or pedestrians gradually ascend or descend by zigzagging back and forth, reducing the steepness of the slope. Switchbacks are commonly used in mountain roads or hiking paths, making it safer and easier to travel on difficult terrain by creating more manageable turns. These sharp turns allow vehicles or hikers to maintain control and prevent accidents.
