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.
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 weight to sit in a booster seat is...40 pounds AND the age of 4 years, BUT preferably the child is longer.
A child must be at least 25 kilograms or nine years of age before being able to leave the booster seat
10 years
There is no age restriction for the front seat in New York. Children, however, must be in the proper child safety seat, harness/vest or booster seat until eight years of age. It is recommended that children sit in the back seat until 12 years of age.
The age in which a child can stop using a car seat or booster seat varies from state to state. In Michigan, the child safety seat law says that a child under the age of eight years old must be in a safety seat unless they are taller than 4' 9.
there isnt an age, it depends on the hight of the child :)
New laws require a rear-facing car seat for children until at least age 1 and at least 20 pounds. Then a forward-facing car seat until the child is at least 5 years old or weighs 40 pounds. A booster seat is then required until 6 years of age. To follow the law, in Alabama, a child can be no younger than 5 years old and use a booster seat.
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.
The current guideline is that the child stay rear facing until 2 years old or they outgrow the height and weight requirements for their seat. They must then stay in a forward facing seat or booster seat until age 8.
It is not age but pounds for a child seat. Check with your DMV, but I think it is over 40lb.
