        Winter is dangerous because it's so difficult to know what is going to happen and 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

snow, waiting ahead to send you off the road. The car coming to you may suddenly slip across the road.

Here are some rules you can follow:

         Rule No. 1 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(careful) and slow as possible. Suppose you are driving with a full cup of hot coffee on the seat

next to you. Drive carefully so that you wouldn't spill it.

        Rule No. 2 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 this distance on snow, and even more on ice. Try to stay in the control of your car at all times and you

will not get into trouble.
