NEXCO EAST Kanto Regional Head Office (Saitama City, Saitama Prefecture) conducted a second winter tire wearing condition survey this year at a rest facility in the jurisdiction in the middle of January with the aim of raising awareness of safe driving on snowy roads. did.

The average percentage of winter tires installed was 73.3% for small cars, 97.4% for large cars, and 80.6% for all car models. Compared to the previous survey (conducted December 12, 2018, December 16th, 2018), we can see an increase in winter tire installation rates for both small and large vehicles. Especially for small cars, we found that the installation rate increased significantly from 57.9% to 73.3%.

　Even in the Tokyo metropolitan area, where it normally does not snow, road surface freezing and snowfall can occur. Even in January 2018, heavy snowfall occurred in a wide area centering on the Tokyo metropolitan area, and there were road closures at Expressway in the area, as well as many slip accidents.

　Running with summer tires on snowy or frozen roads is extremely dangerous, so for customers who are heading to snowfall areas, continue to prepare winter equipment for the car, such as wearing winter tires or carrying tire chains. And drive safely.

If heavy snowfall such as "Heavy snow special warning" or "Emergency announcement by the Ministry of Land, Infrastructure, Transport and Tourism against heavy snowfall" is expected, please refrain from going out unnecessarily and urgently. When going out, please consider detouring to an area less affected by snow.

3 Request from NEXCO EAST Kanto Regional Head Office

• Please "wear early winter tires and carry a tire chain before snowfall".
  Since summer tires are prone to slip on snowy roads, slip accidents on winter roads can lead to serious accidents, so please wear winter tires early and carry the tire chain.
• Please drive slowly and safely when driving on snowy roads.
  Even if you are wearing winter tires, please keep the distance between cars enough and keep your speed down. Do not operate with sudden changes such as sudden steering or braking, and drive slowly and safely.
• Please "collect information before and after going out".
  The weather on the Expressway winter changes rapidly. Even if the place of departure is sunny, it may snow at the destination or at the passing point, so be sure to check the road and weather information frequently before and during your trip.

In this winter, we will cooperate with weather news company Weathernews Co., Ltd. and collaborate with other Expressway companies to provide a new information site "Snow Expressway Impact Prediction" so that the above information can be delivered to more customers. In case of heavy snowfall, please check the information provision site and ask for your cooperation such as withdrawal of your trip to the heavy snowfall area and detouring over a wide area.
