What part of the vehicle reduces whiplash during collision?
- The safety belts.
- The rear bumper.
- Correct answer: The head rests of the vehicle’s seats.
- The air bags.
Why this is the answer
The correct answer in the official bank: The head rests of the vehicle’s seats.
The head rest sits right behind your head and catches it when your body is thrown backward, especially in a rear-end crash, which prevents the neck from snapping back. It works best when adjusted to head height and close to the head. Safety belts and air bags mainly protect against forward movement, and the rear bumper does nothing to support the head.
