All accidents have a cause. Most traffic accidents are the result of bad driving. Therefore, it is important for each driver to improve his driving skills. A good driver must drive carefully and pay attention to all traffic rules. He must also share the road with others and drive at the right speed. Sometimes, the condition of the roads or bad weather makes driving more difficult. But a good driver drives safely in difficult conditions. Trouble, however, often comes from other drivers. Careless drivers make mistakes. In fact, they are a danger to themselves and to others on the road. That is why the best driver is a defensive driver. A defensive driver tries to prevent accidents by predicting what other drivers are going to do. This is driving to stay alive.
