Hello！I'm John. I'm a student. My home is far from the school. Usually, I go to school by bus. Sometimes I go by bike, because it's good exercise. I have a sister. She is a student, too. We usually go to school together. My sister tells me that we must remember the traffic rules: stop and wait at a red light. Slow down and stop at a yellow light. Go at a green light. Do you know the traffic rules?
