On June 24, 2016, people from diverse backgrounds met around a table at the IIHS offices in Arlington, Virginia, to continue the good work begun at the Underride Roundtable on May 5, 2016. This time, we rolled up our sleeves and hammered out a written recommendation for better rear underride guard requirements for tractor-trailers. To save lives.
First of all, we heard a presentation from Raphael Grzebieta on the approach which Australia is taking to improve rear underride protection in their country.
- News of Australian proposed underride rule April 2016
- Proposed Australian Underride Rule section
- Powerpoint presented by Raphael Grzebieta: Under-runRaphCommittee
The basic idea is that they are not concerning themselves with spelling out detailed design specifications (e.g., what loads a guard needs to be able to withstand) but simply outline the performance evaluation criteria of: prevention of underride with the result of a survivable crash (with no injury criteria but instead relying on the crashworthiness of the passenger vehicle). While we might not yet be ready for that radical of an approach, we were given some food for thought.
(If anyone else had a different perception or would like to clarify my simplified explanation, please let me know and I can edit this description.)
Then, we had some useful discussion about the goals for improving underride protection, as well as some of the challenges which trailer manufacturers face. We benefited from some heated discussion which helped us to clarify terms and priorities. (See the bottom of the post for the Meeting Binder which I handed out for discussion purposes.)
After a break for lunch, we got down to work and spent some time brainstorming. As suggestions were tossed out for discussion, Andy Young typed up the suggestions , which were projected onto a screen for us to analyze and refine. Andy worked us hard and enabled us to reach a consensus and common ground upon which we could all agree.
What we came away with was a very good draft of recommendations for updated rear underride guard regulations for tractor-trailers. We also decided upon a tangible process for moving forward:
- David Zuby will send the list of recommendations to me.
- I will mail them out to the meeting participants.
- They will make suggestions for revision, if appropriate.
- We will come to a consensus for the creation of a final document to which we are all willing to sign our names.
- Then I will distribute that document to the entire list of participants of the original May 5 Underride Roundtable — giving them the opportunity to review it and decide if they want to sign it as well.
- We will then send the document to NHTSA via the Federal Register as a Public Comment on the Underride Rulemaking from the Coalition of Stakeholders Interested in Underride Prevention (CSIUP). [Tentative title for our group for lack of a better name to which we can refer]
We agreed to wait for future meetings to address other topics of importance* in the drive for underride prevention. These include such vital things as protection at higher speeds than 35 mph, Single Unit Trucks (which currently have inadequate or non-existent underride protection), side guards, front override, parking and conspicuity issues, and retrofitting.
*Additionally, we briefly discussed the decades-old controversy of “too rigid guards” causing unintended injuries, deceleration forces, need for energy absorption, etc. See my thoughts on that: Urgent Underride Discussion of Deceleration Forces/High Speeds. Don’t Dawdle.
And today, I recorded my thoughts about this confusing issue. I hope some will take the time to listen. In any case, expressing it was helpful to me:

- A Mom’s Knee-Jerk Reaction to NHTSA’s Proposed Rule to Improve Rear Underride Protection The basic problem is that the proposed rule is simply adopting the Canadian rule which 93% of existing trailers already comply with and does not address offset crashes. So it is not much of an improvement, plus it does not address side or front and SUTs. Or retrofitting.
