Turn sign
A yellow diamond with an arrow bent at a right angle. It warns of a sharp turn in the road 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 instead of the Curve sign ahead of bends with an advisory speed of 30 mph or less. Some turn signs carry that advisory speed on the sign itself or on a plaque below it, as Pennsylvania's manual notes.
