Practice question

Warning signs have what color scheme?

  1. Green with White letters
  2. Red with White letters
  3. Yellow with Black letters
  4. Blue with White letters

Answer: C — Yellow with Black letters

Warning signs typically have a yellow background with black letters. This color scheme is easily visible and draws attention to important warnings and hazards ahead. Options A, B, and D do not follow the standard color scheme for warning signs and may cause confusion or make the sign less noticeable. Green and blue are often used for informational signs, while red is reserved for stop and prohibition signs. Therefore, C is the best option for warning signs.
