Road Safety Alert - Warning of Dense Fog

12.10.2021

The Road Safety Authority (RSA) is warning road users of the dangers posed by fog following a yellow weather warning from Met Éireann forecasting dense fog tonight and tomorrow morning across Leinster and Munster.

Met Eireann has issued a yellow Dense Fog warning for Carlow, Clare, Cork, Dublin, Kerry, Kildare, Kilkenny, Laois, Limerick, Longford, Louth, Meath, Offaly, Tipperary, Waterford, Westmeath, Wexford, and Wicklow from 1am -11am Wednesday.

Dense fog seriously reduces your visibility and makes driving very dangerous. Switch on headlights and fog lamps, reduce your speed and keep a safe distance from the vehicle in front. If the fog closes in, reduce your speed further and take your time getting to your destination.

Road users should listen to weather forecasts and general advice about driving conditions and if you must drive in fog, allow plenty of extra time for your journey. Before setting out, check that your car is in good working order, particularly that all the lights, including fog lights, work properly and are clean

The RSA is also advising vulnerable road-users such as pedestrians, motorcyclists and cyclists to ensure they are clearly visible to other road-users by wearing high visibility clothing and using lights.

Other tips for road users include:

  • Switch on headlights and fog lamps if visibility is reduced
  • As you enter fog, check your mirrors and slow down. Use your foot brake lightly so that your lights warn following drivers.
  • Do not drive on the tail-lights of the vehicle in front (Target Fixing). This can give a false sense of security and you will be too close to be able to brake safely.
  • Beware of other drivers who are not using their headlights.
  • Switch off distracting noise and open the window slightly so that you can listen for other traffic, especially at crossroads and junctions
  • Carry a mobile phone, high visibility jacket and torch in the event of a breakdown or collision. In the event of a breakdown park the vehicle well in off the road, get out and stand well back from the side of the road. Phone the emergency services and do not attempt to stand or walk on the road.
  • Beware of speeding up as soon as visibility improves slightly. In patchy fog you could find yourself “driving blind” again only moments later
  • Remember to switch off your fog lights when visibility improves.
