There are some people rode bicycles to red light,and not listen to the police's command; Some people cross the road,but don't walk on the sidewalk; There are some people turn over the guardrail in order for their convenience,but block the traffic; There are also some people drive after drinking,such actions already damaged public facilities,and there will have safe hidden trouble!In these circumstances,I think people should obey traffic rules,improves own quality,cherish oneself life!
