DOT Motorcycle Helmet Guide
New riders (and shoot, old riders for that matter) often wonder what DOT Motorcycle Helmets are. You’ll hear people bounce the word around and maybe you realize it’s related to safety, but the question will remain: what does “DOT” mean? And more importantly, how the heck does DOT relate to Motorcycle Helmets?
Well hey, relax. I’m here to set the record straight and help you understand just exactly what a DOT Motorcycle Helmet is, and what it means for you.
First things first: DOT stands for “Department of Transportation”. It’s pretty straightforward: a DOT sticker on a motorcycle helmet means that helmet meets the safety standards of the Department of Transportation. The importance of this lies (apart from safety) in the fact that states with helmet laws usually require you to wear DOT-certified motorcycle helmets. Fortunately, it’s really tough to find a motorcycle helmet that’s not DOT certified. This is because all motorcycle helmets sold in the United States must, by law, meet the DOT safety requirements.
But what do those requirements mean, and before we answer that, just what the heck even ARE they?
Understandable question, and thus, I’ll explain. The facts of what goes into the design of DOT Motorcycle Helmets can be explained in a few broad categories (Oh and if for some reason you’re bored enough, feel free to check out the NHTSA website for a more in-depth explanation of all this). And by knowing these few basic criteria, you can learn how to verify whether a DOT motorcycle helmet is a genuine or a fake if you’re buying from an unfamiliar dealer.
So here ya go folks, the basic criteria by which you can recognize a genuine DOT motorcycle helmet:
First: Inner Liner. This is the polystyrene foam that’s truly responsible for absorbing the force of an impact and protecting your skull and brain. A genuine DOT motorcycle helmet is gonna have a liner that’s about an inch thick, so if you pick up a helmet with a DOT sticker and the shell is extremely thin, or just plain plastic, then you know it’s not the genuine article.
Second: we’ll look at rivets, chin straps, as well as helmet weight and surface design. These are a few design features that give you a “quick glance” idea of whether a helmet is legit. Rivets and chin strap are easy to recognize: does the DOT motorcycle helmet look like it’s gonna hold together?Does it have a chin strap?How bout weight? Genuine DOT motorcycle helmets will weight somewhere around three pounds. Again, this isn’t an exact science. The idea is simply that the helmet doesn’t feel like it’s only a pound or so. Finally in this category: design. It’s against regulations for a DOT motorcycle helmet to have surface features protruding beyond 2/10ths of an inch. So, sad though it may be, a german motorcycle helmet with a huge spike ain’t no DOT-certified helmet.
So there you have some quick, fast ways to get a “gut check” on whether a helmet is genuine DOT certified. Usually there’s nothing to worry about, but in a sketchy set of circumstances, it never hurts to be prepared. Just because there’s a sticker on a helmet doesn’t always mean it’s the real deal. So if you ever end up buying from a private party, just make sure you’re bolstered with some basic knowledge of DOT motorcycle helmet’s aesthetics and design!
