NEXCO EAST Niigata branch (Niigata city Chuo Ward) conducted a winter tire wearing rate survey in four service areas (SA) and parking areas (PA) on highways such as in Niigata Prefecture on Tuesday, November 28 did.

As a result, the wearing rate for winter tires improved by 90% on all vehicles (100% for large vehicles, 87% for small cars) and the installation rate improved from the previous survey, but still less than 10% small cars are not installed .

This survey is aimed at raising the early exchanges of winter tires and enlightening the safe driving of the snow road, and we do it every week until the installation rate reaches 90% for both large and small cars.

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.
