You are driving in the NT and see a road-works zone with reduced-speed signs. What are your obligations?

1. Slow to the posted work-zone speed limit, be prepared to stop, and obey any traffic controller
2. Maintain normal speed; work-zone signs are advisory only if workers are not visible
3. Only slow down when actually passing workers; normal speed applies between work-zone signs
4. Double your following distance but maintain the normal speed limit
