We have made a commitment to have more salt stocked at the start of winter than was used across Scotland in the entire winter of 2010-11.We also have a stock of more than 100,000 litres of alternative de-icers that will work in the severest of conditions when road salt becomes less effective—usually around 8° below freezing or below—and we are providing guidance for operating companies on when to use these de-icers.We also have a strengthened network of weather stations and new cameras at 24 sites to improve decision making.
