3 Request from NEXCO EAST Niigata branch office

  • "Tire wear for early winter" thank you.
    This year in the prefecture on November 15-17 Expressway In the whole area, we observe first snow and carry out snow removal work. Snowfall is expected in the plains area in the future, so please change to early winter tires.
  • "Driving slowly and safely on snowy roads" please.
    At the beginning of the snowfall season there is a tendency for traffic accidents to occur even if wearing tires for winter is installed because the driving feeling on the snowy road has not returned.
    Beyond the usual inter-vehicle distance and moderate the speed, do not operate "sudden" such as "steering wheel", "rapid acceleration", "sudden braking", etc. Please slow and safe driving.
  • Please collect "Frequent information gathering before going out and going out".
    Since the weather changes suddenly in the winter Expressway , snow may be falling at the destination and the passing point even if the starting place is sunny, so please wear a tire for winter and carry a tire chain.
    Also, please frequently check road information and weather information before going out or in the service area.
