You're probably thinking of a booster seat.
That depends on how old of a child. If the child is in a car seat or booster seat, then no. Studies and actual accidents have shown that children and infants can be beheaded in the front seat if airbags deploy. The child needs to be buckled in the back seat, center if possible.
Yes if the air bag has an on/off switch. But if this is a car with a back seat and not a vehicle with no back seat, place the child in the rear. This is the safest place for a child.
not sure of exact age but if child is in a child seat it's a better idea to keep them in the back to avoid airbag injuries.
It doesn't tend to be illegal (of course that varies by state/country) but in the event of a collision, the child would be much safer in the back seat than in the front. Under no circumstances should a child in a rear facing booster seat be placed in the front seat as if the airbags deploy, the child will probably be killed.
it's seat front
In Arizona a child must be at least 5 years old to not require a child restraint, however, a child restraint need not be placed in the back seat. It is unsafe for a child of under 12 to ride in the front seat if there is an air bag.
In the state of Illinois, a child must remain in the back seat until age 12. Even then it is not recommended that they ride in the front seat because they could be seriously injured or killed if the air bag opened.
There is no law stating that a child has to ride in the rear seat of a vehicle. For safety reasons, it is better for a child to ride in the rear seat due to the fact of many recorded deaths involving children and airbags.
Yes
Nevada children under the age of 12 need to be properly restrained in the back seat
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).
The child should sit in the back until 12 for safety, but the child could sit in the front when they're 8. They have to be 57 inches or taller.
