Signs giving instructions around roadworks are…?
- Legally enforceable ✓
- Only applicable to site traffic
- Optional
- Only applicable to large vehicles
Answer: A. Legally enforceable
Signs giving instructions around roadworks are legally enforceable.
Why this is the answer
The handbook's temporary-condition signs include construction-zone messages telling drivers to drive slowly and watch for instructions, obey a lower speed limit, merge in the open lane, and not pass the pilot vehicle. Those are directions drivers must follow, not suggestions meant only for people working on the site. That is why the enforceable choice fits: the signs control traffic through the work zone.
Why the other answers are wrong
- B. Only applicable to site traffic — They are not limited to site traffic; the handbook presents them as directions for drivers approaching and passing through the work zone.
- C. Optional — They are not optional, because the handbook tells drivers to obey the speed limit, merge as indicated and not pass the pilot vehicle.
- D. Only applicable to large vehicles — They are not restricted to large vehicles; the temporary-condition signs address ordinary traffic using the road.
Remember it
Roadwork signs are orders, not notices.
