Traffic Accidents in Britain
Each year hundreds of thousands of people are injured or killed on the roads in Great Britain, or rather, between 100,000 and 200,000 people are injured or killed in road accidents.
If you are in England and if you listen to the eight o'clock news from BBC, you will often hear news of road accidents. You may hear something like this, "On Monday evening, at about twenty to ten, a cyclist was knocked down by a truck at the crossing of Oak Road and High Street in Croydon. The cyclist has died from his injuries. Anyone who saw the accident please communicates with New Scotland Yard."
Accidents are often caused by carelessness. If everybody obeys the rules, the roads will be much safer.
In Great Britain traffic keeps to the left. Motors--cars, trucks, buses and bikes must all keep to the left side of the road. In most other countries, traffic keeps to the right.
Before crossing the road, stop and look both ways. Look right, look left, and look right again. Then, if you are sure that the road is clear and there is nothing coming, it is safe to cross the road. If you see children, old people, or blind people waiting to cross the road, it is a kind act to help them cross the road in safety.

If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.
Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard.
Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849.
Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.
