Here in BC it is illegal to have a child in the front seat of a vehicle (seat belted or not unless there is an airbag deactivater). They must be in the back seat with seat belts and shoulder harnesses in place. Yet every day I pick up my grandkids from the school bus stop and they do NOT have to wear seat belts in the school bus (there aren't any seat belts in there). If I get caught driving them without seat belts in place I will get a hefty fine. But if you put 50 kids in a school bus they don't need to be restrained?
