What are the colors of the warning signs that indicate hazards ahead, such as curves in the road or narrow bridges?
- Black letters or symbols on a white background
- Black letters or symbols on a yellow background ✓
- White letters or symbols on a blue background
- White letters or symbols on a green background
Answer: B. Black letters or symbols on a yellow background
Warning signs that indicate hazards ahead have black letters or symbols on a yellow background.
Why this is the answer
The handbook groups signs by color and shape. It says warning signs are normally yellow and diamond-shaped, and they carry black letters or symbols. It also explains that warning signs tell you a hazardous location or a special rule is ahead. Curves and narrow bridges are hazards, so the sign color you should expect is yellow with black markings. That is why the choice with black letters or symbols on a yellow background fits.
Why the other answers are wrong
- A. Black letters or symbols on a white background — White with black letters or symbols is how regulation signs are described, not warning signs for hazards.
- C. White letters or symbols on a blue background — Blue with white letters and symbols is the handbook's description of service signs, so it does not mark hazards ahead.
- D. White letters or symbols on a green background — Green with white letters and symbols identifies destination signs, not warning signs.
Remember it
Think yellow for a hazard ahead, green for where you are going, and blue for services.
