To reduce whiplash injuries, what should be the space between your head and the head restraint?

More than 10cm or 4 inches
Less than 10cm or 4 inches
Exactly 10cm or 4 inches
As close as possible

The correct answer is: Less than 10cm or 4 inches

To reduce the risk of whiplash injuries, the ideal space between your head and the head restraint should be less than 10 cm or 4 inches. This close positioning of the head restraint is significant because it helps to limit the backward movement of your head in the event of a collision, thereby reducing the likelihood and severity of neck injuries. If the head restraint is too far away—more than 10 cm—there is a greater risk that the head will move excessively when the body is thrust forward suddenly, leading to whiplash. The design of head restraints aims to support the head and neck during a crash, and ensuring they are positioned correctly is crucial for effectively minimizing these types of injuries.
