Barry Aldworth of AA Ireland says motorists heading out today should leave extra time for journeys.
He said:: "Sunday is traditionally a quieter day on the roads anyway, but if you are one of those making a journey to the family, or if you have been down the counhtry for the weekend and you are coming home, just allow yourself some extra journey time.
"Watch in particular for areas of roads where they might be covered by trees, because they will take longer for ice to defrost, meaning that the roads could stay slippier for longer."
