3. Three points for driving safely Expressway in winter

1. Early winter equipment (installation of winter tires, carrying chains)
   • Winter is just around the corner, so please switch to winter tires early.
   • Make sure the tread depth of your winter tyres is no more than 50% of what it was when new.
   • Be sure to use winter tires when driving on snowy roads.
   • In heavy snowfall, you may be required to use chains even on winter tires, so be sure to carry chains with you.
2. Drive safely and reduce your speed (especially in early winter!)
   • Do not perform sudden actions 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 can change suddenly on winter Expressway, and even if it's sunny where you start, it may be snowing at your destination or at a passing point.
     Please check road and weather information frequently before setting out or when taking a break at a service area.
   • "Drive Traffic (DraTra)" provides real-time traffic information and information on Expressway road conditions (snow road live camera).

4. Getting stuck in snow

• It is easier to get stuck when there is snow.
• 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.
