Warning, Construction & Information SignsStandalone practice
On a rural road you see a yellow diamond-shaped sign with a black symbol that you do not know. What do the shape and the color of the sign tell you?
Correct answer: It warns of a hazard or special condition ahead; be ready to slow down
Why
Sign colors and shapes carry meaning even when you cannot read the words: yellow for warnings, orange for road work, green or brown for destinations and blue for services. A warning sign usually stands before the hazard, which gives you time to react. Wisconsin law requires a lower speed when a special hazard exists.
