At one time, the only danger on the roads was from wild animals. Now the roads are full of cars, trucks and buses. These vehicles are as dangerous as the wildest animals. Every day people are killed while crossing the roads. 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 often killed because they are careless. They forgot to look and listen before they cross the roads. A car, truck or bus cannot stop very quickly. If the car is going very fast, it travels many meters before it stops. Walkers don’t always understand it. 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 people to know how fast the cars is traveling. He may think it is going slowly. The only safe way to cross the roads is to look both ways, right and left. Then if the roads are clear, it is safe to cross. It’s not safe to run when they cross the roads. |
