Did you read the link? Where did you see anything prohibiting child safety seats, where they can be properly secured?
For common sense safety, make sure that any front airbag in child seat location is disabled automatically (based on weight) or manually. Airbags could cause, rather than prevent, injuries to small people. Although, I am not in PA, my GMC work truck has a key switch in the glove box to disable front passenger airbag. Otherwise what would people with pickup trucks do if they have no back seat?
