This sign means?
- School area ahead
- Pedestrian control sign
- Flagman on duty ahead
- Road work ahead ✓
Answer: D. Road work ahead
The sign means road work ahead.
Why this is the answer
The handbook groups signs for road work zones, detours, lane closures and traffic control people as temporary condition signs, and it lists road work ahead among them. That matches the bank answer. The passage about temporary condition signs says these warn of unusual temporary conditions such as road work zones and lane closures, so the sign is telling you to expect road work rather than a school or pedestrian condition.
Why the other answers are wrong
- A. School area ahead — A school area warning belongs to the school zone sign, which warns about a school zone, not a temporary road-work condition.
- B. Pedestrian control sign — A pedestrian control sign relates to pedestrians and crossings, while the handbook lists road work ahead separately as a temporary condition sign.
- C. Flagman on duty ahead — A person controlling traffic is listed as its own temporary-condition warning, separate from the road work ahead sign.
Remember it
Think temporary when the road situation can change: work, detours and lane closures belong to that group of signs.
