question 16(multiple choice worth 3 points)
(lesson 5.3 lc)
head restraints
○ protect against whiplash injuries
○ only help in head - on collisions
○ only help in side - impact collisions
○ absorb energy from rear - end collisions

Explanation:

Head - restraints are designed to limit the backward movement of the head during a collision, especially in rear - end collisions. Whiplash injuries occur when the head is suddenly jerked backward and then forward. By limiting the backward movement, head - restraints protect against whiplash injuries. They are not only for head - on or side - impact collisions. Also, it is the crumple zones and other parts of the vehicle structure that mainly absorb energy in rear - end collisions, not the head - restraints.

Answer:

protect against whiplash injuries
