Roads could once again become slippery between Saturday night and Sunday morning due to ice sheets and frozen snow, the Royal Meteorological Institute (RMI) warned.
A yellow alert issued by the institute takes effect from 7:00 PM on Saturday evening to 11:00 AM on Sunday throughout the country.
Traffic jams have already developed on Saturday afternoon in the Ardennes Heights, particularly at the Baraque Fraiture, Touring Mobilis reported on its website.
