The weight has to be between 85 pounds to 100 pounds. (max. to min.)
The age has to be 11 or older.
500 lbs.
70-90 pounds.
This means that the minimum weight has been met on the passenger seat for the airbag to be turned on.
it has to do with the air bag when it is deployed, a small child sitting in the passenger seat can sustain terrible injuries
Yes they do. My 06 Dakota has 4 weight sensors in the passenger seat.
The AAP instructs to go by height, not weight now (2010) -- a minimum height for a child's no longer needing a booster seat is four feet, nine inches. 4'9."
It is safe and legal for a child of any age to sit in the front passenger side of the car. They must have the correct child restraint for their height and weight.
The passenger seat has a weight sensor which automatically turns the airbag 'on' at a certain weight. If there isn't enough weight in the seat, the system determines that there is no passenger in the seat and leaves the airbag OFF. The weight sensor can also cause the passenger airbag to deploy with less force if it determines the passenger is small and might be injured by a full-force deployment.
there is not really a legal age but a legal weight, legal weight is at least 85 lbs. or whenever the child is tall enough to be out of a booster seat if they do not already weight 85 lbs. but this is mostly up to your judgement as a parent, grandparent, uncle, aunt, or cousin
In most newer cars, no. Older cars may not even have an airbag for the passenger. In most cars that do however, there is a weight sensor in the passenger seat that turns the airbag on only if there is someone heavy enough in the seat. This prevents the airbag from deploying if no one is in the seat and also prevents it from going off if there is a small child in the passenger seat.
over 100lbs
There is no minimum weight required by law for a child to sit in the front passenger seat in Oregon. It is strongly recommended that the child be at least 12 years old before riding in the front. The air bags can cause serious injury to a child smaller than this. Currently laws are only in effect for children that need to ride in safety seats.
