Just be sure to carry a blanket, flashlight, and emergency food with you. If you get caught in a snowstorm, don’t run your engine to keep warm, you might get carbon monoxide poisoning by doing that. And carry tire chains.
In North Dakota we learned that carrying candles in the car was part of emergency plan - a single candle (and matches/lighter of course) can heat the car interior enough to make the difference between life and death
thermal blankets, GPS and charged (manually chargeable) cellphone and emergency radio also good items
