Signs that are colored orange are:
- Work zone signs. ✓
- Regulatory signs.
- School zone signs.
- Guide signs.
Answer: A. Work zone signs.
Orange signs are work zone signs: they mark construction and maintenance areas.
Why this is the answer
The handbook's standard colors table lists orange as the color for construction and maintenance warning. The work-zone section also says orange is the basic color for devices used in construction and maintenance zones, where those devices direct drivers and protect workers. So an orange sign warns you that you are approaching or inside a work zone, where the handbook says to be prepared to slow down or stop, change lanes, and expect unexpected movement of workers and equipment.
Why the other answers are wrong
- B. Regulatory signs. — Regulatory signs are shown with red, black, or white in the standard colors table, not orange.
- C. School zone signs. — The passages do not list school zone signs under orange; orange is tied to construction and maintenance warning.
- D. Guide signs. — Guide signs are linked with green for direction guidance and are generally horizontal rectangles, so they are not the orange work-zone signs.
Remember it
Think "orange means workers": if the sign is orange, expect a work zone.
