DOT HELMET STANDARDS

Bob, that didn't have a frontal view as well, did it? I'm claustrophobic, so I only buy 3/4 helmets, and then only Shoei and Arai that wrap around the jaw further than most. It would be great to see the front chin impact.......not that I would change, of course

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

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

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%.

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!
