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.
Warning signs are the signs that contain information about hazardous conditions.
Why this is the answer
The handbook puts warning signs in their own group. It says warning signs are usually yellow and diamond-shaped and that they alert drivers to conditions ahead and what to look out for. Elsewhere the handbook lists yellow as general warning and advisory of unexpected roadway conditions. That matches the question's description of signs containing information about hazardous conditions. Regulatory signs control traffic and give commands, while guide and informational signs give directions, distances, or services, so they do not fit this description.
Why the other answers are wrong
- A. Regulatory signs. — Regulatory signs control traffic, set limits, or give commands rather than alerting drivers to hazardous conditions ahead.
- C. Information signs. — Information signs are associated with guide signs that give directions and distances, not warnings about hazardous conditions.
- D. Guide signs. — Guide signs give directional information and distances, so they are not the signs described as warning about hazards.
Remember it
Yellow diamond means heads up: something ahead needs your attention.
