Want this question answered?
the age in cairns is 8 but i do not no the age
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.
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.
You have to check your states requirements for needed height & weight-they don't go by years.
To get out a booster seat you have to be at least 4 feet 9 inches
13 years without a booster if the child reaches the height regulations but if they dont they still must sit in the back with booster
In some places age does matter i think its around 7 8 years old but they also have to meet the weight an height requirements .
They have to be a certain height and weight but booster seats can be used till up to 5 years old
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.
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.
It is not an age restiction. It is a height/weight restriction for saftey from the passenger side airbag. 50 lbs and no booster seat is what is required.
a child can be at leaset 6 to 8 years of age it really doesnt depond on height or weight
