  • 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.
  • And be alert for road workers, the roads are their workplace.
