Gritters will be out from 2am on Wednesday morning, with CORMAC carrying out precautionary salting on 25 routes including the most heavily trafficked A and B roads which between them are responsible for around 85% of traffic movements.

CORMAC warns that even where a road has been gritted, motorists should never assume that a road is safe as black ice, freezing rain and sudden hail storms as well as snow can lead to hazardous driving conditions.
