Severe disruption occurs once visibility drops below 50 metres.

Driving tips

  • avoid travel if possible
  • drive very slowly with dipped headlights to reduce reflection
  • keep an eye on your speed - fog can give you the illusion that you're driving in slow motion
  • use fog lights
  • don't drive too close to other cars
  • watch out for freezing fog as it can quickly form layers of ice
