ALASKA'S ROAD CONDITIONS -- Alaska roads vary from 4-lane, paved freeways to 1-lane dirt and gravel tracks. Driving in Alaska is different from that in the "lower 48" states. Weather, construc- tion, and maintenance all help determine the quality of a road's condition. Know your vehicle and its limit- ations; know also the limitations of the road you plan to travel. Some are not suitable for 40-foot motorhomes or low-to-the-ground sports cars. Many Alaska roads are not paved, and rocks and gravel are hard on tires; in- vest in quality tires, and carry at least one spare. Don't drive too fast on gravel. Watch for frost heaves; driving too fast on these can result in broken axles and trailer hitches. Watch for road construction, and give trucks the right of way. Be especially careful in wet weather on roads with clay surfaces; the mud is very slippery. Watch for chuckholes and washouts. DON'T use cruise control on Alaska roads.
