At what age should a child be kept in a booster seat?

The appropriate age for a child to be kept in a booster seat typically ranges from approximately 4 to 8 years old, depending on the child's size and weight, as well as the specific laws in different states. However, option D states 8-12 years old, which is misleading because by age 8, many children have transitioned out of a booster seat and into a regular seat belt, provided they meet the height and weight requirements for that transition.

The correct answer should ideally align with the age bracket where booster seats are most commonly recommended for ensuring the child's safety while traveling in vehicles. Generally, children should remain in a booster seat until they are old enough and large enough to fit properly in a seat belt, which is often when they reach around 4 feet 9 inches in height, usually between the ages of 8 and 12, based on their development.
