- keep within the speed limit – it is there for your safety
- get into the correct lane in good time – don’t keep switching
- concentrate on the road ahead, not the roadworks
- be alert for works’ traffic leaving or entering roadworks
- keep a safe distance – there could be queues in front
- observe all signs – they are there to help you
