Winding Road Ahead Sign - Meaning, Usage & Safety Tips #1840874 (License: Personal Use)

The image shows a standard U.S. MUTCD (Manual on Uniform Traffic Control Devices) warning sign: a yellow diamond with a black, vertically oriented, S-shaped arrow pointing upward, indicating a series of sharp curves ahead.
