My DC rarely travel in the front and if they do I always turn off the passenger airbag. However DD is soon to be 12 and I will be conveying her and her friends on an outing which will mean I will have a carful and someone will have to sit in the front. Do I turn the airbag off or is it safer at that age to leave it on? Do I sit my daughter or biggest kid in the front? WWYD?
