Depends for me. For instance has it been wet the night before or the route. In the Edinburgh -6deg was my supposed limit below that grit really isn't effective. I did apparently cycle home in -13deg
Down here though roads are less well treated and I think I'd be a wee bit more cautious; it seldomly gets too cold anyway about -3 or -4 deg I think is all I've recorded.
