DD Weather Alert: Thick fog has progressively thickened since this morning on the road between Letterkenny and Dungloe, particularly the Meenaroy and Fintown area.

When driving through fog, the Road Safety Authority urges you to;
>Slow down and increase the distance from the vehicle in front.
>Use dipped headlights and front and rear fog lights, if fitted.
>Open your window a little so you can hear other road users approaching, particularly at junctions.
>Remember to switch off fog lights when visibility improves.
>Keep a sharp lookout for pedestrians, cyclists and motorcyclists.
>Do not blindly follow the vehicle in front – it may leave the road for whatever reason.
>If you have to stop, activate your hazard warning lights
