Wearing a puffy coat while driving might seem like a good idea when it’s cold, but it can actually be unsafe. The bulky material keeps your seat belt from fitting properly against your body, which can make it less effective in protecting you during an accident. To stay safe and warm, try wearing layers of loose-fitting, layered, lightweight clothing in the car and add a hat, gloves, and a scarf. It’s also a good idea to keep a stash of cold-weather essentials in your car, like extra food and water, a flashlight, and blankets, to be prepared for emergencies.
