When you come across roadworks: When you come across roadworks:

  • A. You only have to obey the signs during working hours.

  • B. You only have to obey the signs when there are workers about.

  • C. You must obey the signs that are displayed at all times.

    The correct answer is C
    Correct. Road works signs are there to warn you that the road conditions may be dangerous at any time (e.g. slippery or potentially damaging to your vehicle at higher speeds).

Road works and lane closure signs

Road works are performed to:

In some cases the surface layer of the road will be removed completely and that could leave a loose surface; in other cases the repair can be localise, but gravel or loose stones may still be around the area.

New chip seal will have lots of loose stone chips for a while until they wear away.

If there's a traffic controller the traffic controller will let you know when it's safe to pass through the road works. There might be vehicles coming the other way, or workers or machinery blocking the lane.

Lane closures

If a lane is closed then you will see a sign like this:

left lane closed

Prepare to move to the right. If traffic is heavy then it's likely that it will either be backed up, or it will be starting to back up, so check that traffic ahead of you hasn't stopped suddenly. 

Merge right like a zip (alternate vehicles), and take car. If you are in the middle lane, make room for vehicles merging from the left lane.

If you are in the left lane, be courteous and don't try to jump the queue or sneak up the inside.

If traffic has backed up, beware of motorcyclists filtering through. 

As there is a lane closed there might also be loose gravel on the road surface.

Lane closures might also be caused by workers working in close proximity to the road, e.g. repairing traffic lights, installing signs, working on bridges or gantries, or clearing up spills.

Around roadworks, road workers are exempt from some of the rules that drivers must obey.
