Aocidents could happen at any time. We must be careful all the time on the road, especially on the corner of the road and at traffic lights. The rules on the road are very important. If we learn and follow them, we won't have too many accidents.
Most traffic accidents happen because people are careless. Most of these people are old people and children. Old people usually can't see or hear very well. Children are often too careless. Listening to music on the road is very dangerous. Some drivers drive too fast, so they usually cause traffic accidents. When a car is going very fast, it travels many metres before it stops. Bicycle riders will also cause accidents by changing directions(方向) suddenly.
Before you turn left, you should check twice to make sure there aren't any cars or buses coming. When you want to turn left, you should show your left hand to tell the driver. You should not turn until the street is clear.
When you want to cross the road, you should look at the right side and left side to make sure the road is safe. Remember not to play on the road.
