Warm Hat and Gloves
Staying warm is the most important survival tactic when you're stranded in the winter. It's always a good idea to have an extra hat and gloves so you (or an under-clothed guest) can keep warm while getting your car out of a ditch, changing a tire or taking a look under the hood.
Digging out compacted snow from under the car or around the wheels is much easier with a proper shovel. Plus, using your hands, even in gloves, can cool you down fast. When you don't have room for a full-size shovel (and really, who does?), the next best thing is a foldable shovel. You can pick them up online or in military surplus stores. Maybe the best tip, though, is becoming a better winter driver. Learn our best winter driving tips here.
