Question

post-test
which passenger compartment part helps protect against whiplash?
a. brake pedal
b. headrest
c. knee bolster
d. seatbelt

Explanation:

A headrest is designed to limit the backward movement of the head during a collision, reducing the risk of whiplash. A brake pedal is for stopping the vehicle, a knee bolster is for knee protection in a crash, and a seatbelt restrains the body but not specifically the head for whiplash.

Answer:

B. Headrest
