Priority order for road salting

Roads are treated in a priority order, in line with national guidelines.

We routinely treat only the first priority routes in the event of forecasted ice, frost or snow and we carry out this treatment in advance of the forecasted conditions to achieve the most effective results. In other words we focus our efforts on enabling the safe movement of traffic on first priority roads as far as possible . Lower priority roads are not treated in this way. It is important that drivers take extra care during severe weather and drivers should not assume that all roads have been treated.

Circumstances which may prevent road salting from taking place

No matter how accurate the weather forecast, there are some situations where we do not salt the network prior to icy conditions because this would be ineffective:

Pavements and footpaths (footways)

Busy pedestrian routes will only be salted at times of prolonged sub-zero temperatures and when there is persistent frost or ice. Other pavements and footpaths are not salted.

For advice on clearing snow and ice from pavements yourself, see the snow code on the Met Office website:

Cycle tracks
