It was already 3：15 when I got up this afternoon. Classes would begin in a quarter. I quickly ran out and got on my bike.
On my way to school, I rode fast. When I reached the crossing, the traffic lights were red, but I didn't stop my bike. A policeman stopped me, and asked me why I didn't stop when the lights were red. I told him that I would be late for the class. He told me with a smile to obey the traffic rules next time and let me go.
We should obey the traffic rules whenever.
