Tennessee F Endorsement Driver's License Practice Test

The correct position for head restraints is even with the back of the head because this alignment is crucial for effectively minimizing the risk of whiplash during a rear-end collision. When the head restraint is positioned at or just slightly below the back of the head, it can absorb some of the impact forces and limit the backward motion of the head that causes whiplash.

When head restraints are positioned too far above the head, they lose their effectiveness, as they cannot provide adequate support during a collision. Similarly, if they are set farther back than the head or below the neck, they leave a gap that can allow the head to move backward uncontrollably, increasing the likelihood of injury. Proper positioning helps maintain the natural alignment of the spine and provides necessary support. In essence, adjusting head restraints to the appropriate height is a simple yet critical step in enhancing safety in vehicles.
