Minimum of age 8 AND 4'9". The car seat belt must fit snuggly across the child's hips with both feet on the floor and the shoulder belt must not be cutting into their neck. Some 8 yr olds are this tall, but most are not. The size of the child is the most important factor.
the weight to sit in a booster seat is...40 pounds AND the age of 4 years, BUT preferably the child is longer.

The child's size is the factor here. If the seatbelt comes across their body like it does for you, then they do not need a booster seat. Sometimes, the child's weight is a factor, too. They should be at least 90 pounds in weight before they are allowed out of the booster seat.
In order for a child to no longer have to use a booster seat, they need to be between the ages of 4-9 & must also be 4 foot 9 inches by law.
When they about the height of 4'9".
The age that a child should use a car seat booster is when they are 2 years of age. Some kids need to use them a little bit earlier because weight and height has an effect on how earlier the kids need to use the booster seat.
I heard it was supposed to be by weight, not by height, but what do i know.....when they outgrow the carseat
in all states a child has to be 4foot nine to be out of a booster seat. they can be in a booster sear at any age.
The Booster offers safe, comfortable rides for someones child. Moving from a car seat to a booster seat still helps the child remain safe, while riding comfortably in the booster seat.
age 7 though if the child's shoulders are lower then back seat back rest,advice is to use booster seat
The AAP instructs to go by height, not weight now (2010) -- a minimum height for a child's no longer needing a booster seat is four feet, nine inches. 4'9."
4 The answer is NOT based on age but on the height and weight of your child. If your child is over 40lbs he/she can transition to a booster seat with lap/ shoulder restraint.
