Certain highway signs contain information about hazardous conditions. Such signs are known as:
- Regulatory signs.
- Warning signs. ✓
- Information signs.
- Guide signs.
Answer: B. Warning signs.
Signs that contain information about hazardous conditions are warning signs.
Why this is the answer
The handbook says diamond-shaped signs are used only to warn about existing or possible hazards on the road or beside it. It also explains that warning signs tell you about conditions just ahead, such as road hazards, a change in direction, or another situation you need to know about. That matches the question's description of signs containing information about hazardous conditions. The handbook adds that you should pay attention to warning signs for safety and that ignoring them can be a traffic violation.
Why the other answers are wrong
- A. Regulatory signs. — Regulatory signs tell drivers what they should or should not do and must be obeyed like traffic laws, so they are not the hazard-information category described in the passage.
- C. Information signs. — The passages do not assign hazard warnings to information signs; they place that role with warning signs.
- D. Guide signs. — Guide signs are not described in the passages as hazard-warning signs, and the handbook gives that role to warning signs instead.
Remember it
Think diamond for danger ahead: warning signs tell you what to look for.
