The Road Safety Authority (RSA) has urged road users travelling during the period of the warning to take extra care, warning of the additional danger posed by thick fog.
Due to poor visibility, drivers are advised to switch on dipped headlights and fog lamps, reduce their speed and allow an extra safe distance to the vehicle in front.
The RSA has also advised that drivers should portion extra time for their journey, while other vulnerable road users, such as pedestrians and cyclists, are asked to ensure they wear high-visibility clothing and use lights.
