NEXCO EAST Kanto Regional Head Office (Saitama City, Saitama Prefecture) conducted a winter tire installation status survey (first step) at a rest facility in the area in mid-December to raise awareness of safe driving on snowy roads. did.

　The average winter tire installation rate was 67.4% for all models, 91.9% for large vehicles, and 57.9% for small vehicles.

On snowy / frozen roads, summer tires cause more accidents than winter tires.

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 on summer tires on snowy or frozen roads is extremely dangerous, so please wear winter tires or carry a tire chain 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.

1 Overview of winter tire installation status survey

(※ next time, 2019 around the middle of January, survey plans)

Survey location

2 Results of winter tire installation status survey (number of surveys: 3136 in total)

Winter tire installation rate (by metropolitan area / snow areas)

• In the Tokyo metropolitan area, the installation rate is 34.8% for small cars and 91.4% for large cars.
• In snowfall areas, the installation rate is 89.5% for small cars and 92.7% for large cars.

Winter tire installation rate (year-on-year comparison)

• Compared to the same period last year, in the Tokyo metropolitan area, large vehicles have already exceeded the installation rate of last year, but the installation rate of small vehicles is still low. On the other hand, in the snowfall area, both small and large vehicles are lower than last year.

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.

"Prediction of snow impact on Expressway"

When heavy snowfall such as "heavy snow special warning" or "urgent announcement by the Ministry of Land, Infrastructure, Transport and Tourism against heavy snowfall" is expected, we will provide information on Expressway closures due to heavy snowfall from about 3 days ago.

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.
