Wearing a seat belt as required:

- Correct answer: Reduces the extent of injury during an accident.
- Keeps the driver alert.
- Reduces the driver’s movement in his seat and prevents accidents.
Why this is the answer
The correct answer in the official bank: Reduces the extent of injury during an accident.
The seat belt is a passive safety device: it does not prevent the accident itself, but protects the wearer when the accident happens. It holds the body in the seat and reduces the risk of hitting the steering wheel, the windshield and parts of the vehicle, and of being thrown out of the vehicle. In this way it reduces the extent of injury to the wearer.
