Every year a lot of people got injured or died in traffic accidents. It is reported that many accidents resulted from people‘s breaking of traffic rules. So it is necessary for all to keep the traffic rules in mind and obey them strictly.

When one crosses the street， one should take the crosswalk， underground passage or pedestrian overpass. If one is riding a bike or motorcycle， keep riding on the right side of the road. When the red light is on， please stop and wait until the green light is on. Give a hand signal if one wants to turn or stop. It is important to let the children know that playing on the road is very dangerous. Helping the aged and children cross the road is always a kind deed.

If everyone obeys the traffic rules， it will be much safer to walk or ride on the road.
