3 Request from NEXCO EAST Niigata branch office

  • Please "install winter tires early before snowfall" and "carry a chain".
    Last weekend, we observed snowfall throughout Niigata prefecture and are carrying out snow removal work. As we enter the full-scale snowfall season, it will be extremely dangerous for vehicles without winter tires to drive on snowy Expressway. If you haven't installed the 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 do not forget to carry the chain.
  • 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 departure point is sunny, it may snow at the destination or passing point, so please wear winter tires and carry tire chains.
    Also, please check the road information and weather information frequently before going out or in the service area.
     "Drive Traffic (DraTra)" provides traffic congestion prediction, real-time traffic information, Expressway weather (snow road) prediction, and road surface condition (snow road live camera) information.
