Want this question answered?
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.
I heard it was supposed to be by weight, not by height, but what do i know.....when they outgrow the carseat
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.
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.
Dmv
They have to be a certain height and weight but booster seats can be used till up to 5 years old
A child that is age 8 or younger and weighs no more than 80 pounds can use a booster seat in New Jersey. Children over the age 8 must use a seat belt.
When they about the height of 4'9".
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.
It depends, as they need to fit the weight and height requirements specified in your vehicle manual, to sit in a seat unassisted. Unless there is a local bylaw requiring people of a certain age, height or weight either to sit in a booster seat, or not in a booster seat.
Every age can sit in the front of any car any where in PA. Age 0-7 need to be in a booster. Ages above do not need one.
age 7 though if the child's shoulders are lower then back seat back rest,advice is to use booster seat
