Winter is dangerous for drivers because it’s so difficult to know what is going to happen and accidents take place easily. Bad weather can be waiting to meet you. Ice might be hiding under the snow, waiting to send you off the road. The car coming towards you might suddenly move across the road. Here are two rules for driving safely on icy roads:

Rule Number One is to drive smoothly. Irregular movements can make a car very difficult to manage. So each time you either turn the wheel, touch the brake or increase your speed, you must be as gentle and slow as possible. Just imagine you are driving with a full cup of hot coffee on the seat next to you. You should drive carefully enough in order that you wouldn’t get the coffee out of the cup.

Rule Number Two is to pay attention to what might happen. The more ice there is, the farther you have to look down the road. Test how long it takes to stop by gently braking. Remember that you may be driving more quickly than you think. Generally speaking, allow double your normal stopping distance when the road is wet, three times this distance on snow, and even more on ice. Try to stay in control of your car at all times, or you will get into trouble.
