This sign means?
- Construction ahead ✓
- Lane ahead closed
- Construction zone ends
- Detour ahead
Answer: A. Construction ahead
The sign means construction ahead: it warns you that a construction zone is coming up.
Why this is the answer
The handbook says to scan ahead and look for construction zones ahead, and it says you must obey road construction signs from the start to the end of the zone. That fits a sign telling you construction is ahead. Once in the zone, the handbook says construction zones often need lane closures, so be ready to merge, and watch for traffic control persons, workers and equipment. The passages do not describe this sign's shape, colour or symbol, so the meaning rests on the construction-zone warnings and rules they give.
Why the other answers are wrong
- B. Lane ahead closed — Lane ahead closed is wrong because the passages say construction zones often require lane closures, not that this sign means a lane ahead is closed.
- C. Construction zone ends — Construction zone ends is wrong because the passages say to obey construction signs from the start to the end of the zone, but they do not say this sign marks the end.
- D. Detour ahead — Detour ahead is wrong because the passages discuss construction zones, lane closures and traffic control, but they do not mention detours.
Remember it
When you see a construction sign, start looking ahead for workers, equipment and lane changes.
