The answer, explained
A yellow diamond warns of a road condition or hazard ahead. Its symbol or words identify what you need to prepare for.
The existing picture uses a divided-highway symbol as an example of this warning family. Learn both layers: the color and shape tell you to expect a warning, while the interior symbol explains the particular change ahead.
A common mistake
Recognizing the warning shape without reading the symbol leaves you unprepared for the actual road change.
