Fast driving is always dangerous. Motor-racing is even more dangerous. But have you ever heard of motor-racing which is noisy, fast, exciting and safe?

No? Then perhaps you have never heard of karting, also sometimes called go karting. A kart is rather like a baby car with no roof. It has a small engine, 4 small wheels and room for only the driver. Its top speed is about 80 kilometers per hour. Karting clubs are private and young people under the age of 17 can be members. On the private land of the club, they can go karting.

Some secondary schools think karting is very good for their pupils. The pupils can make everything except the engine and the tyres at school. Tyres for kart are not very expensive. An old motorcycle engine does not cost much and is good enough as a kart engine. The pupils enjoy studies which are part of real life. The school likes karting for another reason. The sport is safe. Because the karts are low to the ground, serious accidents almost never happen. Karting is something new and exciting for these lucky pupils. It also teaches them a lot of engineering. Perhaps they will be better drivers in later life. They may not want to behave (行为举止) like racing-drivers on our dangerous roads.
