A fleet of hilariously named gritters are out salting the roads of Scotland as new snow and ice warnings are issued. "Robert Brrrns," "Ready Spready Go," and "The Great British Flake Off" are among the names given to some of the machines. This clip shows the whereabouts of the gritters on the afternoon of Tuesday (13 December) as they treated roads across the country. A status yellow warning is in place for the north and east of Scotland until Thursday at noon. The Met Office says roads and railways are likely to be impacted by the weather conditions.
