The DOT does a fairly decent job of keeping the roads plowed, but conditions can change pretty quickly. Best thing to do is be prepared by having you vehicle outfitted with winter tires and to carry a good set of chains, that you know how to put on. I'd practice that at least once before heading into snow country. There's nothing more aggravating than trying to put chains on your car in a foot of fresh snow! When it comes to driving in the snow, remember, slow and steady, arrive alive!
