winter driving tips: Avoid driving while you’re fatigued. Getting the proper amount of rest before taking on winter weather tasks reduces driving risks. Never warm up a vehicle in an enclosed area, such as a garage. Make certain your tires are properly inflated. Never mix radial tires with other tire types. Keep your gas tank at least half full to avoid gas line freeze-up. If possible, avoid using your parking brake in cold, rainy and snowy weather. Do not use cruise control
