At one time the only danger on the roads was from wild animals. Now the roads are full of cars, trucks and buses. They are as dangerous as the wildest animal. There are also many more of them.
Every day people are killed while crossing the road. Most of these people are old people and children. Old people are often killed because they usually cannot see or hear very well. Children are killed because they are careless. They forget to look and listen before they cross the road.
A car, truck or bus cannot stop very quickly. If the car is going very fast it will travel many meters before it stops. A person who travels on foot in a street does not always understand this. They think a car can stop within a few meters. The faster a car is traveling, the longer it takes to stop. It is very difficult for a walking person to know how fast a car is traveling. He may think it is going slowly when it is going very quickly.
The only safe way to cross the road is to look both ways, right and left and right again. Then if the road is clear, it is safe to cross. The corrct way to cross the road is to walk quickly. It is not safe to run. If people run across the road, they may fall down.
