Big kid riding in the front seat of the car?

I am interested to know, at what age would you be comfortable with your child riding in the front seat of your car? Do you know if there is a law about this in your state?

    I let my niece ride up front with me when she turned 12, she's 4 inches shorter than me.
      12 will be the soonest I will let my kids ride in the front seat. The seat belt must have a perfect fit and they must be tall enough because of the airbag.
