A car seat or booster is required until your child is 8 years old or taller than 4'9".

A child under 4 must be in a child restraint (rear-facing until age 2). A child 4 to 7 who is not taller than 4 feet 9 inches must be in a car seat or booster. From age 8, or once taller than 4 feet 9 inches, a seat belt is allowed.
