On Expressway, even one vehicle that cannot drive on its own can lead to long-term traffic jams and road closures. When using Expressway, be sure to wear winter tires and carry tire chains in case of sudden snowfall or freezing, and especially when driving on snowy roads, please wear chains. .
For winter tires, please attach studless notation (domestic notation) or snowflake mark (international notation) to all wheels, and attach chains to drive wheels.
