When you come across roadworks:
Road works and lane closure signs
Road works are performed to:
- repair potholes and other tarmac degradation on a local, small scale area
- resurface roads that have outlived their life
- build new roads, intersections and roundabouts
- install services such as underground pipes or wire, new traffic lights or signs
- maintain services
- paint or repaint road markings
- change the road layout
- speed and traffic restriction construction such as building chicanes or speed bumps
- grade gravel or dirt roads.
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:
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.
