Correct Response: B. Since the majority of severe car crashes involve front-end collisions, these are the most important events to protect an infant against. Add to this the facts that infants' heads are disproportionately heavy compared to their bodies, their spines are not fully formed, and their neck and shoulder muscles are not fully developed. In a front-end collision, the infant's heavy head will tend to continue moving forward as the car is stopped. Therefore, the best way to protect the infant is to face the car seat towards the back of the car so that the infant's head is restrained from motion by the car seat headrest. The softness of the seat of the car (A) is of no relevance since the infant will not come into contact with it. A car's seatbelt is equally capable of holding a front-facing or rear-facing car seat securely (C). In addition, most modern cars come equipped with brackets designed specifically for securing car seats. If properly secured, an infant is not likely to be thrown from a car seat (D) regardless of the direction that it is facing.
