In Australia there is a small external label that indicates the helmet meets Australian Standards. It is segmented so its very difficult to remove and place on a different helmet. Also would be difficult to reproduce.
This argument is typically in the Legislation section but I fully support helmet laws. I agree that anyone should do what they what... Unless it affects someone else. The fact remains that non-helmet use accidents typically increase medical expenses which would increase premiums (thus affecting many individuals).
Australia has mandatory helmet laws for bicycles as well and thank god for that. I had an accident 10 years ago where I lost it coming around a turn on a gravel patch doing 45km/hr. Head hit the edge curb, split the helmet in two and I was unconscious for 2min. would not be alive to tell the tale.
