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、12月8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4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大型車99％、小型車83％であり、前回調査より装着率は向上しましたが、まだ小型車の約2割が冬用タイヤを未装着でした。今年度は既に新潟県内高速道路の山間部で初雪を観測しており、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

• 『降雪前に早めの冬用タイヤ装着』と『チェーンの携行』をお願いします。
  　今年度は既に新潟県内高速道路の山間部で初雪を観測しており、これから本格的な降雪期を迎えます。冬用タイヤを未装着のまま雪道を走行することは大変危険となりますので、まだ冬用タイヤを装着されていない場合には、早めの交換をお願いします。
  　また、大雪の場合には冬用タイヤであってもチェーン装着が義務付けられる場合がありますので、チェーンの携行も忘れずにお願いします。
• 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).
