How to tell if there are roadworks ahead

Roadworks signs are usually in orange, white and black. If traffic is merging from the left, be courteous and merge like a zip.

Some GPS units will warn of roadworks. You can also check websites such as NZTA's traffic map.

Roadworks could mean any of the following hazards are present:

  • lanes are closed
  • there is an uneven surface or gravel on the road
  • there are temporary stop signs or traffic lights in place 
  • road marking is happening
  • verge and median strip maintenance is happening (e.g. mowing, weed spraying)
  • there's a new layout you need to be aware of
  • work is being done on signs or gantries such as cleaning or maintenance
  • road worker's vehicles may need to pull into site access entranceways.
