A slow-moving vehicle emblem is:

  1. A rectangular red sign.
  2. A circular green sign.
  3. A diamond-shaped yellow sign.
  4. A triangular orange sign. ✓

Answer: D. A triangular orange sign.

A slow-moving vehicle emblem is a triangular orange sign.

Why this is the answer

The handbook says the slow-moving vehicle symbol is a reflective orange triangle. It is displayed on the back of vehicles drawn by animals, most farm vehicles, and construction equipment, and rural mail delivery vehicles also use these orange safety triangles. The shape and orange color are what identify the emblem, so the answer that describes a triangular orange sign matches the handbook description.

Why the other answers are wrong

Remember it

Link the orange triangle in your mind with slow farm equipment and rural mail trucks.
