How old must a child be to sit in the front passenger seat in 2021?

[MacWilliam]

According to 2021 regulations, children must be at least 12 years old to sit in the front passenger seat. Necessity of safety seats: In real life, due to children's smaller body proportions and bones, sitting in the front passenger seat is very unsafe. In case of an emergency, they are easily injured by the deploying airbag. Therefore, it's best to have children sit in the rear seats. Requirements for children in vehicles: Parents should never hold children while sitting in the front passenger seat, children should not lean out of windows to view scenery while the vehicle is moving, children should not stand on the center console during rides, and children should never be left alone in the vehicle.
