"We follow our agreed winter maintenance plan but continue to ask anyone using the road network to use the greatest possible care when travelling and be aware of the weather forecast.
"Even if it were feasible to grit all the city's 1,900km of roads and 3,100km of footways every day, wintry weather will always pose risks to road users and pedestrians."
