Bumper sticker for adults

Those baby on board stickers are to let paramedics and first responders know that there is a baby in the back seat in the event of an accident and to go to them first. Also that post and all the adults on board stickers just make you look like a dick in my opinion for putting your life before a child's

The first guest to comment is absolutetly correct
The stickers of baby and child on board is to notify the first responders that there is a people on board incapable of unharnessing themselves too

I don't think a sticker on the back window qualifies as a bumper sticker since it's not on the bumper
