Winter is dangerous because it’s so difficult to know what is going to happen and traffic accidents take place so easily . Fog can be waiting to meet you over the top of a hill. Ice might be hiding under the melting(融化的)snow, waiting ahead to send you off the road. The car coming to you may suddenly slip across the road.

Rule Number One for driving on icy roads is to drive smoothly. Sudden movements can make a car very difficult to control. So every time you either start or stop your car, increase or reduce your speed, you must be as gentle and slow as possible. Suppose you are driving with a full cup of hot coffee on the seat next to you. Drive so that you wouldn’t spill  it  .

Rule Number Two is to pay attention to what might happen. The more ice there is, the further down the road you have to look. Test how long it takes to gently stop your car. Remember that you may be driving more quickly than you think. Generally, allow twice of your usual stopping distance when the road is wet, three times on snow, and even more on ice. Try to stay in control of your car at all times ad you will not get into trouble.
