There are so many bikes, cars and buses on the roads, so we must obey the traffic rules all the time.
Children under 12 cannot ride bikes on the street. When we ride bikes, we should keep both hands on the handlebars(把手).①We should ride bikes on the right of the road in our country.
②Like drivers of cars or buses, we must follow(遵循) all traffic signs. All of us know we must not turn left or go across the street at a red traffic light. Usually we can turn right, but we shouldn't ride too fast. If we want to turn or stop, we must give a sign to others.
