Winding road sign
A yellow diamond with a wavy line. It warns of three or more curves in a row ahead.
Rules vary by state and country. This explains the sign's standard meaning in the U.S. Manual on Uniform Traffic Control Devices; it isn't legal advice.
How to read it
The MUTCD uses it in place of several Curve or Turn signs where there are three or more bends, each less than 600 feet from the next. A plaque below it reading NEXT XX MILES can give the length of the winding stretch.
