What I've learned over the years about driving in the snow.
Not to preach, but when I first started to drive I wish someone had taught me these things.

1) Listen to the weather report, if they are calling for six inches ( and you get six inches ) and your car had a ground height of four inches, don't expect to be going anywhere when the snow ends until the roads are plowed.

2) Keep the moisture outside the car, clean the snow off your boots when getting in the car, particularly if you have rubber floor mats. Condensation builds up inside quickly.

3) Cars heading uphill have the right-of-way, harder to get up a hill. If heading down hill be courteous and acknowledge the person trying to get up the hill.

4) Read your owners manual about gear selection on downhill runs. So much to know about downhill slippery conditions I wouldn't begin to preach.

5) Keep a shovel in your car. If your health is an issue someone else can use it.
