No. As they're not intended for use with ground vehicles (such as motorcycles), they're not even evaluated by the DOT.
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.
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.
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.
"Dot" is "DOT" - Department of Transportation. So DOT Approved means "Approved by the Department of Transportation".
When a motorcycle helmet is DOT certified, that means it has been certified by the United Stated Department of Transportation, following strict safety standards. Once a helmet has been DOT certified it is identified with a sticker on the helmet itself. Unfortunately, not every helmet sold that has a DOT sticker is DOT compliant. Visit the following site for a partial listing of the most popular brand helmets. http://www.helmetcheck.org/database.aspx CarlGlas Any helmet that is DOT approved will have a sticker on the helmet. If you go to a helmet manufacturers website, it will state what certifications the helmet has.
What does DOT and SAE approved means
No.
SNELL is an addition safety rating for helmets. The SNELL Foundation certification is more stringent than DOT certification.
It means something has been approved by the Department of Transportation.
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."
