I was just surfing around tonight and I found some interesting stuff. First the Motor vehicle act of Nova Scotia. Here's a link. I realize most of you don't live here but it might be worth your while to look into your local laws and regulations and find out specifically what they say. http://www.gov.ns.ca/legi/legc/statutes/motorv.htm
Here's the helmet law:
170 (1) No person shall operate or ride as a passenger on a motorcycle or motor scooter on a highway unless he is wearing adequate protective headgear of a kind prescribed by regulation of the Governor in Council.
(2) Regulations made under subsection (1) may adopt by reference or otherwise standards or specifications established or approved by the Canadian Standards Association or other testing organization with or without modifications or variations or may require that any headgear conform to the standards or specifications established or approved by the Canadian Standards Association or other testing organization or bear the approval of the Canadian Standards Association or other testing organization.
I read this over a couple of times and thought I should look into it further so I went to find out exactly what the regulation of the Govenor in council was. That's when I found this http://www.gov.ns.ca/just/regulations/regs/mvhelmet.htm
1 These regulations may be cited as the Helmet Regulations.
2 A person operating a motorcycle or motor scooter must wear a helmet that bears a mark indicating that the helmet is approved or certified as a motorcycle or motor scooter helmet by one or more of the following certification agencies:
(a) the British Standards Institute;
(b) the Snell Memorial Foundation;
(b) the United States of America Department of Transportation.
I find it funny that they don't specify that the helmet must be approved but instead specify that the helmet must bear a mark. I think if any of you with those little novelty helmets ever got a ticket for it you could fight the ticket and win. For that matter you could argue with the cop that the regulation states that the helmet bears the mark and yours in fact does, (assuming you have a DOT, SNELL, or BSI sticker on your beanie).
