No. When a child reaches age 8 (regardless of weight) OR reaches 80 pounds (regardless of age), a properly fitted seat belt may be used instead of a child restraint/booster to restrain the child. However, keep in mind that the seatbelt may not fit properly even if the child is 8 years old or weighs 80 pounds. The law does require that children stay in a child restraint or booster seat until the seat belt fits properly on its own.
Booster seats are for children who have outgrown convertible or toddler seats. Booster seats are for children who are 4 to eight 8 old, weigh 40 to 80 pounds, and are less than 4 feet, 9 inches in height. You can use a booster seat until an adult seat belt correctly fits the child without use of the booster seat.
