Keep Warm Clothes, Blankets, and Water in Your Trunk in Winter

A highway breakdown or a snowstorm can trap you in your car for hours — sometimes overnight. A blanket, a warm layer, a water bottle, and a few snacks are the difference between discomfort and hypothermia. Add a phone charger, a flashlight, and an ice scraper. You probably won't need any of it — but the one time you do, you'll understand why it mattered. Pack it once in November, unpack it in March. That's the entire effort.
