It is late at night in a signed construction speed zone. No workers are visible. Does its posted speed limit still apply?
Correct answer: Yes, even when no workers are present.
Why
Obey the posted construction or maintenance speed limit whether or not workers are present. Narrow lanes, barriers, pavement changes, and other hazards can remain after work stops. Slow further if needed for the actual conditions.
