How does a seat belt save lives?

Answer 1

If a car is going at 60 miles an hour (100 km per hour) and it hits a wall, everything inside the car keeps going at the same speed. So if you are not wearing a seat belt YOU keep going, and you hit the windscreen, or the steering wheel at 60 miles an hour. That's a lot of blood and bone and skull. Not good! And if you crash head on into another vehicle going at 60 miles an hour, then it's like you hit the wall at 120 mph. Wow! This is why children should always be in the back seat, (not in the middle), and never sitting on the lap of the passenger in front. This is also why it's not a good idea to have a big dog in the back seat, or some heavy boxes. What happens to them in a crash? In a crash, the seat belt will probably give you bruises, but that's much better than the other thing! So - "Clunk click, even on the shortest trip"
