The safest thing you can do during a snow storm is to stay off the roads. Not only is driving during snowfall treacherous for you and your vehicle, it can be life-threatening for pedestrians. Slow-moving and abandoned cars also interfere with first responders and plow operators—better not to take a chance if you can avoid it. Mostly importantly, do not abandon your car in the middle of the road.
If you must drive, slow down and watch for ice, hills, and ditches.
Be sure to clear your car of all snow and ice before leaving for your destination.
When driving at night, keep your headlight beams low. High beams can amplify the appearance of snow and lead to decreased visibility.
