Reminder to all. The topic is helmet safety, not geopolitics.

They even build a lot of the campus buildings with Hokie Stone.

with this, I often wondered how an organized event require a person to have a helmet to cover liability issues when the rating used to eval the safety equipment is subjective?

That's the best part of the campus as far as I'm concerned. Penn State has built some really ugly buildings just in the time we have been here.

Given legal liability concerns and the existence of legally recognized standards, subjective or otherwise, how far would you expect the organizers of an event to get in a court case brought against them by an injured (or worse) participant with the claim that "We didn't require the use of certified helmets because the certification is based on subjective impressions"?

i'd expect a signed waiver prior to participating in the event to alleviate the organizers from the other persons liability? Now if negligence is a factor, that's a different ball of wax on a sweltering day that no waiver could rescue an organization from.

Does any organized event specify a minimum helmet rating in it's "requirement?"
I have my doubts if an organized event requirement for a helmet "covers" its liability for negligence in any way, but may be useful for discouraging participation by the alleged riff raff who don't fit the profile desired by the organized ride/event leaders.

sifting thru the ones brough up in the events section here seems to have it in the fine print when ya dig into the links when available.

Digging and sifting through the events section to find "it" exceeds my BF forensic capabilities. I would be surprised if any non racing event registration fine print about participant requirements specifies words more descriptive than "helmet required," with no explanation and racing events might specify "CPSC certified helmet required."

I would not be surprised if questioned about a helmet requirement for event participants, event organizers might respond with a rote response "Our insurance requires it" whether that statement is true or not.
I would be very surprised if any event registration (or insurance company) specified a minimum helmet rating or number of stars assigned by VTI except perhaps a CPSC certification for racing events.

I would be even more surprised if any event official ever checks the ratings or certification labels of the helmets being worn by the event participants.
