You see a diamond-shaped sign with an orange background ahead. The sign means:
-
A.
A general warning about a permanent road hazard.
-
B.
A work zone or road construction is ahead. Correct
-
C.
A nearby historic or cultural location.
-
D.
A school crossing or pedestrian area ahead.
The answer is "A work zone or road construction is ahead."
Orange is the work zone color. Diamond-shaped orange signs warn you that road construction or a work zone is ahead, and orange cones, drums, and signs guide you through it. Yellow diamonds carry permanent warnings (curves, merges, slippery when wet). Brown signs point to historic or recreational sites. School signs are five-sided and yellow. The shift from yellow to orange is the cue that the warning is temporary, and traffic fines are doubled in all work zones.
The traps in the wrong answers
A. A general warning about a permanent road hazard.
Permanent warnings use yellow diamonds. Orange signals a temporary work zone. Misreading: Confuses orange work-zone signs with yellow warning signs. The manual defines work zones by orange traffic control devices; yellow is reserved for permanent warnings.
C. A nearby historic or cultural location.
Historic and cultural locations are marked with brown signs, not orange. Misreading: Confuses orange with brown. Brown signs point to historic and cultural locations, while the manual assigns orange specifically to work zones.
D. A school crossing or pedestrian area ahead.
School crossings use five-sided yellow signs, not orange diamonds. Misreading: Confuses the orange diamond work-zone sign with the five-sided yellow school sign; color and shape both differ.
