In our city have many traffic problems that created by people who don't know the rules of traffic safety.Too many people using the road make many long jams ; traffic accidents every day make of the people unconscious ; young people riding their bike dangerously because they want to show everyone that they are cool , etc,.Everyone need to learn some rules about using the road , so our problems will decline, no more traffic problems can happen.
