Signs that are colored orange are:

  1. Work zone signs. ✓
  2. Regulatory signs.
  3. School zone signs.
  4. Guide signs.

Answer: A. Work zone signs.

Orange signs mark work zones, warning you that people are working on or near the roadway.

Why this is the answer

The handbook's signs chapter lists work area signs as orange with black letters or symbols, and explains they mean people are at work on or near the road, with traffic possibly controlled by a flag person. It adds that a reduced work area speed limit may be posted, and even without one you must slow down and obey flag persons. The defensive driving chapter repeats that orange diamond-shaped signs are work zone warning signs placed before construction and other work areas that can change traffic flow.

Why the other answers are wrong

Remember it

Think of orange as the color of construction crews' safety vests: orange means workers ahead.
