NEXCO東日本新潟支社（新潟市中央区）では、冬用タイヤの早期交換を喚起し、冬道の安全運転を啓発する目的として、11月24日（火）に新潟県内などの高速道路4カ所のサービスエリア（SA）・パーキングエリア（PA）で今冬期2回目の冬用タイヤ装着率調査を実施しました。
　冬用タイヤ装着率は全車で 73％（大型車 97％、小型車 67％）であり、前回調査より装着率は向上しましたが、まだ約3割のお客さまは冬用タイヤを未装着でした。これから本格的な降雪期を迎えるため、早めの冬用タイヤへの交換とチェーンの携行のご協力をお願いします。

3. 3. Request from NEXCO EAST Niigata Regional Head Office

• Please "install winter tires early before snowfall" and "carry a chain".
  Expressway prefecture, and the full-scale snowfall season is about to begin. It is very dangerous to drive on snowy roads without winter tires installed, so if you have not installed winter tires yet, please replace them as soon as possible.
  Also, in the case of heavy snow, you may be required to attach a chain even for winter tires, so please be sure to carry the chain with you.​
• Please drive slowly and safely when driving on snowy roads.
  At the beginning of the snow season, driving sensations on snowy roads have not been restored, and even with winter tires, there is a tendency to cause traffic accidents.
  Make sure to keep the distance between vehicles more than usual, and keep your speed down. Do not perform operations with "sudden" such as "sudden steering wheel," "accelerated acceleration," or "sudden braking" and drive slowly and safely.
• Please "collect information diligently before and during your outing".
  The Expressway winter changes suddenly. Even if the starting point is sunny, it may snow at the destination or passing point, so please wear winter tires and carry tire chains.
  Also, check road information and weather information frequently before going out or in the service area.
  "Drive Traffic (DraTra)" (https://www.drivetraffic.jp/) provides real-time road traffic information and Expressway surface conditions (snow road live camera).
