If your car gets stuck in snow or ice, remove the floormats from the car and place them under the tires. This will usually give you just enough traction to get free. (Don't forget to pick the floormats back up!)

Cut up a fairly large cardboard box, and leave it in your trunk for snow stuck cars....
Along with this idea, is if you replace your floormats, keep the old ones in the trunk for this purpose and also in case you need to change a tire, it will give you a "cleaner" surface to lean on.
Branches broken off a nearby tree also give traction - but I've used this when stuck in mud as it NEVER snows where I live in Australia!
