This morning I was late for school so I became caught in a serious traffic jam in my way to school. The traffic jam was causing by an accident. A girl hit by a bus while she was crossed the road. She was in so a hurry that she ran a red light. Just as she was crossing, a bus turned into my bike. It was too late for her to stop her bike so she is knocked over. She hurt her leg very badly. I think this accident is not a good lesson for all of us. It tells us the important of obeying the traffic rules even when we are in a hurry.
