Tire chains are illegal in quite a number of states and are only legal for semis in other states. I have had snow tires in the past; but a set of all season radials with GOOD tread works much better. A front wheel drive is much easier to drive in snow than rear wheel drive vehicles.
I never change my speed or lanes when driving on a bridge or deck, I have seen so many accidents because someone decides to speed up or slow down or switch lanes while on a bridge and the roadway is icy. Give yourself and every other driver room to get out of the way of accidents.
Always have a small shovel, kitty litter, a full tank of gas, and a winter survival kit in the car when travelling in the winter. The survival kit includes: (and can be packed in) a large coffee can, a space blanket, candles, matches, a smaller tin can, toilet paper, flashlight with new batteries, and hard candies or trail mix. You also need to have warm waterproof boots, warm jacket, insulated gloves, warm hat, heavy duty snowbrush and ice scraper with you in the car whenever you are out driving. And a cell phone has definitely saved a few lives here in Mn. these past few years.
If you are stuck in a ditch or on the road, NEVER leave your car to go get help! Getting cold or wet can cause a rapid loss of body heat, which may cloud your thinking and put you in danger of losing your life. Use the space blanket, put on the warm boots, coat, hat and gloves. Lighting a candle in one of the tin cans will produce enough heat to keep you warm, run the car motor only 10 minutes out of each hour. You can melt snow in the other coffee can to drink warm water if you are stuck any length of time (sorry, Amy, but bottled water has always frozen for me and those bottles don't thaw out well).
My first car was a '71 Pontiac Firebird with a huge engine and a light body. I was in the ditch more than out of it while I had that car, and I've never been in the ditch since. I do remember spending some tense hours in the ditch once back then; it's always important to stay calm.
If you keep your wits about you, plan ahead, and don't take stupid chances, you won't mind winter at all. (Of course, you have to know that I moved from northern Minnesota to southern Mn. for the warmer weather!)
