DOT HELMET STANDARDS
Occasionally on SL, we'll have questions on helmets... people ask which are the best, etc...
my answer always was, "if it has a DOT sticker on it, it means it meets the gov't standards"...
i no longer think this way after reading various articles such as these:
https://ultimatemotorcycling.com/201...e-22-05-snell/
http://www.bikersrights.com/nhtsa/fmvss218.html
http://silodrome.com/snell-vs-dot-vs...rds-throwdown/
After educating myself, i'll be looking at helmets from a completely different perspective... hope you do too....

I spent 30 yrs employed by the US gov't. in contract management. One of my primary functions was enforcing 'gov't standards' and accepting certifications. You get a little numb after awhile.
IMO far too many gov't. agencies accept certifications without any effort whatsoever to determine if they are valid.
Their mindset ( again IMO ) is that if it has a signature it is OK.
Can you spell horsepuckey?

Meets Government Standards
Well, most politicians also meet "government standards," so I am not so sure if that is a positive or not.
Seems these days the standards are pretty low.

SNELL is the highest standard. Above and beyond DOT. They are an independent testing agency Typically, only full face helmets get both the DOT & SNELL ratings.

ECE surpasses DOT and Snell and is pretty much the standard for bikes. ECE is the only one of the 3 that does abrasion testing.
Keep in mind that just because a helmet isn't Snell rated doesn't mean it wouldn't pass. Snell currently will not pass helmets with internal visors or modular helmets, even if they would physically pass the tests. Many manufacturers forgo Snell testing because due to the cost to test.

Personally, I worry more about the type of helmet I wear vs the certification (full face vs open face vs 1/2). It's been proven that the cheeks/jaw/facial area is the most common area for damage in a crash.

Hi DrewNJ,
Re: ECE surpasses DOT and Snell
I am not familiar with ECE, could you provide some more info?
I used to keep up with this stuff, not much so more.
ANSI still has their Z-90 standard: http://standards.globalspec.com/std/437430/ansi-z90-1
ANSI is recognized thoughout the engineering world for all kinds of standards.

Here is a pretty good Reddit conversation too. Not technical, but a good discussion none the less...
https://m.reddit.com/r/motorcycles/c...met_overrated/
IMHO, I don't worry so much about the specific certifications. It's hard to go wrong with any modern major manufacturer full face helmet. The key is also that it fits right. [emoji106]

Hi DrewNJ,
Re: Here is a good read
Thanks for the link; I might just spend a night reading all of it.
However, when the article says: They test helmets in a few funky ways under a few even funkier conditions.
they get me to wondering what the real testing is.
Thanks,
Jerry Baumchen

Same helmet, different sides.

So why the different values? Why would the left side protect differently than the right side?

This is a depiction of where helmets are impacted during collisions, not where they're test impacted nor the impact resistance. It would be good to know where the data comes from but it looks like the right side takes more hits than the left side. This would kind of make sense if the data is all from right hand highways and so many of the collisions are with cars coming from the right.
I didn't add them up but the total of all the percentages should be right at 100%.

That is not about protection, it is about frequency of impacts by percentage.

It came from the Hurt Report.

Wearing a 3/4 doesn't change the percentages. It just means you are 30-45% less protected based on the impact studies and your helmet configuration.

You mentioned that it came from the Hurt Report: how oddly appropriate!
