Visibility is often limited in winter by weather conditions. Slow down and watch for other vehicles that have flashing lights, visibility may be so restricted during a storm that it is difficult to see slow moving highway equipment. When stalled, stay with your vehicle and try to conserve fuel while maintaining warmth. Be alert to any possible exhaust and carbon monoxide problems. You must stop and put on traction devices when highway signs indicate chains are required.
Japan uses international signs easily identified by foreigners.
Control areas can change rapidly from place to place because of changing weather conditions. The speed limit when chains are required will also be posted. When you put on traction devices, wait until you can pull completely off the road to the left. Do not stop in a traffic lane where you will endanger yourself and block traffic. There are signs indicating special pull-off areas to remove traction devices.
