Roadworks and Closures
Roadworks and temporary closures help maintain and improve the roads, but they also create hazards. You must slow down, follow the signs, and obey any directions from flaggers, cones, or temporary signals.
Legal Essentials
- You must obey temporary traffic lights, cones, barriers, and flaggers. [2]
- You must follow instructions from police or road workers controlling traffic. [2]
- You must not drive carelessly or without consideration — ignoring temporary control is an offence. [1]
Good Practice
- Slow down: Road surfaces may be uneven, narrow, or slippery.
- Watch for workers: Always be alert for road workers close to traffic.
- Keep distance: Maintain safe space between you and the vehicle in front — sudden stops are common in work zones.
- Follow signs early: Lane closures and diversions are signposted in advance. Plan your move into the correct lane in good time. See Lane Discipline.
- Be patient: Delays are common. Aggressive driving in work zones puts lives at risk.
Special Considerations
- Flaggers: Treat instructions from a flagger with the same authority as a police officer.
- Temporary signals: Obey red lights even if the road looks clear — the other side may have priority.
- Closures: If a road is fully closed, you must follow the marked diversion route. Do not drive past “ROAD CLOSED” signs.
- Emergency vehicles: If sirens or flashing lights appear in a work zone, follow flagger or police guidance. See Emergency Vehicles & School Zones.
Exam Pointers

- What must you do when approaching roadworks? → Slow down, follow signs, and be ready to stop.
- Is it legal to ignore a “ROAD CLOSED” sign if the road looks passable? → No. You must follow the diversion.

Can I drive past a ROAD CLOSED sign?
No. You must follow the diversion route. Ignoring closures is illegal and dangerous.
How should I merge when lanes are closed at roadworks?
Merge in good time when safe. Do not push into the queue or change lanes suddenly. See Lane Discipline.
Why are speed limits often reduced in work zones?
To protect both workers and drivers. Road surfaces may be uneven or narrowed, and sudden stops are more likely.
