PCS travelers are authorized to drive the Alaska Highway year-round, including the winter months (mid-October to mid-April). Be aware that when the summer tourist season ends, many facilities along the highway close for the year, including gas stations. Alaska-Canada travel guides indicate which facilities will be open during the winter. Winterize your vehicle prior to the trip. A block heater, oil pan heater, transmission pan heater and battery pad or battery blanket are the standard items. Studded snow tires should be considered, and tire chains should be carried for winter trips. Finally, be sure to carry appropriate cold-weather emergency equipment, including warm clothing, extra blankets or sleeping bags, a small folding shovel, safety flares, flashlight, matches, food, water, a signaling device and a first aid kit.
