What color marks construction and work zone signs in Oregon?
-
A.
Orange Correct
-
B.
Red
-
C.
Green
-
D.
Yellow
The answer is "Orange"
Construction and work zone signs and devices use orange. When you see orange, you are approaching road work: slow down, watch for workers, and expect changes in lane configuration. Yellow is reserved for general warning signs like curves, pedestrian crossings, and animal crossings, while orange is the cue for temporary work zones specifically. Reaching for D means carrying over the warning-sign yellow drivers see far more often and reading it as the work-zone color too.
The traps in the wrong answers
B. Red
Red is reserved for prohibitive regulatory signs like stop and do-not-enter. This answer confuses regulatory red (stop, do-not-enter) with the orange that defines work-zone traffic control devices.
C. Green
Green marks guide and information signs (exits, distances), not construction. This answer confuses guide-sign green (exits, distances) with the orange that defines work-zone traffic control devices.
D. Yellow
Yellow marks general warning signs (curves, pedestrian crossings), not work zones. This answer confuses general warning-sign yellow with the orange used specifically for temporary work-zone traffic control devices.
