Gritters will be working through rush hour in Sheffield tomorrow morning when snow and icy conditions are expected to hit.
Snow has been forecast on high ground from around dawn.
Amey, the Streets Ahead contractor, will be out to deliver precautionary gritting from 6am.
Eleven gritters will be working through the peak travel period to disperse around 40 tonnes of grit with all operations hoped to be complete by 9am.
