I heard it was supposed to be by weight, not by height, but what do i know.....
when they outgrow the carseat
i think it is when they are 1.3m tall or 13
4' 3'' Trust me dude u don't want it to fall out.
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.
No, regardless of the child's age, a booster seat should NEVER be used in the front seat. An airbag can kill a child in the front seat if they are not tall enough and heavy enough to properly take the impact of the air bag.
When your child is atleast 80 lbs. or 4' 9" tall or at 8 years of age.
You have to be 140cm
No more than 2 to 2-1/2 feet tall
All children under the age of 12 will have to use some form of child car seat, unless they are taller than 135cm (4ft 5in).
Until you're tall enough.
In the UK yes, but if they are under 140 centimetres tall, they are required to use a booster seat/child seat. (But that goes for the back of the car, as well as the front).
It depends on how tall the child is. Most people would day seven, but in my opinion, it should be based more on size.
"Booster seats are necessary when a child outgrows his/her child safety seat, usually after 40 pounds or age 4. Children do not fit in adult shoulder/lap belts (without a booster seat) until they are 58 inches tall (with a sitting height of 29 inches) and weigh 80 pounds, according to the Centers for Disease Control and Prevention (CDC)."
