3. Three points for driving safely Expressway in winter

1. Early winter equipment (installation of winter tires, carrying chains)
   • Winter is almost here. Please change to winter tires as soon as possible.
   • Make sure that the tread depth of your winter tires is no more than 50% worn down when new.
   • During heavy snowfall, chains may be required even on winter tires. Please be sure to carry a chain.
2. Drive safely and reduce your speed (especially in early winter!)
   • Do not perform operations with the word ``sudden'' such as ``sudden steering,'' ``sudden acceleration,'' or ``sudden braking.''
     Please drive slowly and safely, keeping a sufficient distance between vehicles.
   • In particular, at the beginning of winter, drivers tend to be more prone to accidents as their sense of driving on snowy roads has not yet recovered.
3. Frequently gathering information before and during your outing
   • The weather on Expressway in winter can change rapidly, and even if it's sunny at your departure point, it may be snowing at your destination or passing point.
     Please check road and weather information frequently before going out or while taking a break in the service area.
   • "Drive Traffic (DraTra)" provides real-time traffic information and information on Expressway road conditions (snowy road live camera).

Four. About stacking during snowfall

• Stuck is more likely to occur during snowfall.
• NEXCO EAST official YouTube channel introduces the mechanism by which stacks occur and how to prevent them from occurring. Please take a look at it as a reference for safe driving.

Reference video: "How to avoid getting stuck! ? I will explain how the stack occurs.』
