Until what age or height must children be secured in an appropriate child passenger safety seat? All choices are incorrect. until age 8 or taller than 4'9'' until age 5 or 4' tall until 13 years of age

The correct answer is: until age 8 or taller than $4'9''$.<br /><br />According to the American Academy of Pediatrics (AAP) and the National Highway Traffic Safety Administration (NHTSA), children should remain in a car seat with a harness for as long as possible, until they reach the height and weight limits for the seat. Typically, this is until age 8 or until they are taller than $4'9''$. After that, they should use a booster seat until the seat belt fits properly, usually when they are between ages 8 and 12.
