What color scheme does the manual use for work zone signs?
-
A.
Orange with black lettering Correct
-
B.
Red with white words
-
C.
Green with white text
-
D.
Yellow with black symbols
The answer is "Orange with black lettering"
Work zone signs are diamond shaped like warning signs but switch to orange with black lettering. Test-takers who file work zones as ordinary warning signs pick D, because yellow with black is the standard warning-sign scheme work zones borrow their diamond shape from.
The traps in the wrong answers
B. Red with white words
Red with white appears on STOP, YIELD, DO NOT ENTER, and WRONG WAY signs, not on work zones. This answer reaches for the most urgent-looking color, forgetting the manual assigns orange rather than red to construction and utility zones.
C. Green with white text
Green with white marks highway and expressway guide signs that direct you to cities, exits, and points of interest, not work zones. This answer confuses the color of the highway guide signs posted along the same routes with the color of the construction signs seen on them.
D. Yellow with black symbols
Yellow with black is the standard warning-sign color; work zone signs deliberately switch to orange to set construction areas apart. This answer applies the default warning-sign color that work zones borrow their diamond shape from, missing the deliberate swap to orange the manual calls out for construction.
