SNELL is an addition safety rating for helmets. The SNELL Foundation certification is more stringent than DOT certification.
Helmets in the US are certified by the Snell Foundation, and the Foundation's standards are periodically upgraded. Responsible racing organizations therefore require competitors to use helmets with an appropriate Snell approval sticker inside them. People who use non-Snell-approved helmets are putting themselves at serious risk. As motorcycle stunt man Evel Kenevel famously put it "If you've got a ten-dollar head, go ahead and buy a ten-dollar helmet."
Surprise! as far as is known this is never done! On the other hand crash helmets are certainly tested by the American Standards Association"s famed Z-90 standard which is required for most motorcycle crash helmets- and also the Snell Foundation. Snell, for whom the foundation was named somewhat ironically was an automobile racing driver killed in an accident involving a defective helmet- he was not a Motorcyclist! Nonetheless the phrase Snell Approved honors his name and the safety standard. Z-90 and Snell approved are essentially congruent ( equal ratings) But, Bicycles themselves are not tested by any safety agency in the US!
all helmets are
In most states DOT helmets are required.
All helmets must be DOT approved and have the DOT sticker on them, in the US, when helmets are required.
Motorcycle helmets need to be either DOT or SNELL certified, if the helmet has that certification then you can use a scooter helmet on a motorcycle.
Of course it is, the UK is part of Europe, so European approved helmets are legal in the UK.
They wear fake helmets with no padding, and quick release plastic snaps. They look good for a T.V. show but are not DOT approved and provide absolutly no protection.
Because society got tired of paying for the health care associated with avoidable head injuries on riders not wearing good enough helmets or no helmets at all.
Yes, mc riders in the entire state of Ca. are required to wear DOT approved helmets although enforcement of the DOT requirement is virtually non-existent. Many riders including myself use what are commonly known as "novelty" helmets.
From the Snell Memorial foundation website : "The DOT Motorcycle Helmet Standard is a mandatory minimum for headgear sold for motorcycle use throughout the United States. It is specified in most US jurisdictions where motorcycle helmet use is required. Recently, Canada also requires that motorcyclists wear either DOT or Snell certified motorcycle helmets." The European ECE 22-05 standard is accepted in Quebec and British Colombia. The DOT standard is the US Department of Transportation, SNELL is an independent non-profit organisation, and ECE 22-05 is the European Community standard. In Canada, the CSA no longer certifies motorcycle helmets. Each province in Canada legislates their own motorcycle helmet laws. (Snell is not a racing approval company, just a helmet safety approval company; all of the racing organisations in North America accept the ECE 22-05 standard for racing, but they also accept Snell. And the SA approval is very similar to the M "motorcycle," the main difference is that it must also have a fire resistant lining.
