You must know the traffic if you walk a city. The traffic lights are the same in every city. There always lights. You can cross the street at the light and you must stop and wait at the light. Thelight means "slow down and stop". If you drive car, you must drive on theside of the road in China. But in England, people drive on the side of the road.
