More the ice risk.
I'm in the Highlands of Scotland and very common to have black ice when the air temperature is 1- 2 degrees Centigrade, so the frost warning at 3C is just about right.
Plus temperatures can regularly drop out very quickly up here, so a warning is a good reminder that temperatures can be falling fast.
