How is a driver required to adjust the vehicle’s head rest?
- The upper edge of the head-rest should be aligned with the bottom line of the driver’s neck.
- The lower edge of the head-rest should be aligned with the upper tip of the driver’s head.
- Correct answer: The upper edge of the head-rest should be aligned with the upper tip of the driver’s head.
- Proper adjustment of the driver’s head-rest is of no significance.
Why this is the answer
The correct answer in the official bank: The upper edge of the head-rest should be aligned with the upper tip of the driver’s head.
The head-rest is there to stop the head from snapping backwards in a crash, especially when hit from behind, which protects the neck from whiplash. With its upper edge level with the top of the head, it supports the whole head. A head-rest set too low, at neck level, acts as a pivot that the head bends back over, making the injury worse.
