Which sign uses words to warn about a hazard?

• A. A sign with a pictorial symbol only
• B. A circular sign with a hazard symbol
• C. A triangular sign with a pictorial icon
• D. A sign that uses warning words printed on it

Answer: (D)

Signs can warn of hazards either with pictures or with words. Using warning words printed on a sign makes the hazard explicit through text, which is exactly what this option does. The other signs rely on symbols or images to convey the warning, not on written wording. A sign with only a pictorial symbol, a circular sign containing a hazard symbol, or a triangular sign with a pictorial icon all communicate through visuals rather than words. So the sign that uses warning words printed on it is the one that uses words to warn about a hazard.
