No more than 2 to 2-1/2 feet tall
i believe 4,5
When they about the height of 4'9".
At the age of 8, children can sit in the back seat without a booster seat. They do need to have a seat belt; however, and not be in the front. They need to be securely fastened as well.
To get out a booster seat you have to be at least 4 feet 9 inches
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.
I heard it was supposed to be by weight, not by height, but what do i know.....when they outgrow the carseat
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.
It is not "age" that determines this ... more so "height" and "weight". State laws differ, but there are minimal height requirements for children using the regular seat belts in auto's and trucks.
Not until the seat belt will fit properly without use of a booster seat.
you have to be 136cm or over
When they are around 2 and have outgrown their child seat. They should continue to use a booster seat until they reach the height of 4 foot 9.
135
