Which statement about child passenger restraints based on age and height is true?

• A. Child under 8 years old and shorter than 57 inches must be secured with a child passenger restraint
• B. Child under 8 years old can ride unrestrained if the seat is in the back
• C. Child over 12 does not need a booster
• D. Child only needs a restraint if crossing state lines

Answer: (A)

The rule being tested is how child passenger restraints depend on age and height. In Massachusetts, a child under 8 years old or shorter than 57 inches must ride in a child passenger restraint. This sizing ensures the harness or seat belt is positioned correctly on the child, providing proper support for the head, neck, and torso in a crash and reducing injury risk. Once a child reaches 57 inches or turns 8, they can use the regular seat belt, but a booster may still be needed until the belt fits properly across the shoulder and lap. Riding unrestrained in the back is not safe, and boosters aren’t necessarily unnecessary after age 12 if the child isn’t tall enough for a proper seat belt. Restraint rules apply regardless of crossing state lines.
