Imagine yourself running as fast as you can and suddenly something looms up. What would happen? You think you would able to dodge that thing? But the answer is pretty much no and as a result you would definitely get knocked up. This same situation occurs when the car crashes with another vehicle. Within the first tenth of a second the car stops, but as we are also going with the same speed, so to stop ourselves, we need something, either a dashboard, or steering, in case we are not wearing a seat belt. Seat belts protect driver and passengers from bouncing around, avoid hitting surfaces such as windshield, windows, and doors. They control passenger’s movement and hold them in their place.
