As I contemplated the work ahead of the Department of Transportation and the trucking industry to advance side underride protection, I realized that the lack of a standard for side guards could be a problem. Actually, that is why we gathered together a group of engineers in 2020 to tackle the development of a Consensus Side Guard Standard. But there is a history to the decades-long effort that led up to this which I feel is important to document here:
This is a Timeline of activities leading up to the development of a Consensus Side Guard Standard. It provides a detailed overview of the multiple individuals and organizations who have contributed to raising awareness, researching, and collaborating to create a standard which the government can require and the industry can adopt to bring an end to preventable side underride tragedies.
My hope is that this resource will be reviewed, studied, and turned to as the Underride Initiative moves forward in the coming year. Let’s not reinvent the wheel but rather — with a sense of urgency — let’s build upon the work which has gone before us.
This timeline is not an exhaustive record of all the people who have played a part in advancing underride awareness, research, and protection. There are many people not mentioned here with whom I’ve crossed paths and many who worked on this problem long before I ever became aware of it. Much of that is chronicled in the thousands of posts written on this website.
They are all part of a nationwide, in fact international, Underride Initiative. Thank you, TEAM Underride, for your hard work and dedication to this cause.
We are so thankful for the many people who have contributed over the years to developing effective underride protection. This video was created in gratitude for their hard work. It provides only a brief glimpse and leaves out many people who should rightly be included in this Underride Hero Hall of Fame. Credit goes to the Insurance Institute for Highway Safety for their tour guide’s description of the IIHS underride crash testing efforts at their Ruckersville, Virginia, research & testing facility.
On a Friday afternoon — February 26, 2021 — over 50 people met via Zoom to discuss comprehensive underride protection. The purpose of the meeting was to report on progress which has been made by several subcommittees since an earlier meeting in 2020 — including Industry Engagement, Research, and Engineering Subcommittees.
The goal of the Underride Engineering Subcommittee — to which trailer manufacturers were invited — was to create a Consensus Side Guard Standard which would provide additional insight for the development of a side guard regulation. Lengthy conversation and exchange of information has led this group to submit the following recommendation:
A side underride guard shall be considered to meet the performance standard if it is able to provide vehicle crash compatibility with a midsize car, to prevent intrusion into the occupant survival space, when it is struck at any location, at any angle, and at any speed up to and including 40 mph.
The Task Force went so far as to suggest that the Truck Trailers Manufacturers Association (TTMA) discuss the Consensus Side Guard Standard at their upcoming annual meeting in San Antonio, April 7-10, 2021. We encouraged them to come together in a Joint Agreement to adopt or improve the Consensus Side Guard Standard, as an association, and fast track the manufacturing of side guards by their 80th Anniversary in 2022.
Accept the standard; build a guard.

Sean O’Malley, Senior Test Coordinator at the Insurance Institute for Highway Safety (IIHS), gave a presentation at the Side Guard Task Force. He stated that, “Everything we do here, we do to save lives. I wasn’t kidding when I said the rear underride program (ToughGuard) is what I’m most proud of. ” Trailer manufacturers responded to the IIHS creation of a safety marketplace for improved rear underride guards by working to meet the TOUGHGuardAward level of protection at the rear of tractor-trailers. Why then would they not do the same to meet the Consensus Side Guard Standard of protection at the sides of tractor-trailers — particularly since the IIHS supports it with their 40 m.p.h. test?
Underride is underride no matter with what part of the truck you collide — because the bottom of large trucks sit up higher from the ground than the bumpers of passenger vehicles. All the way around.
So now what do we do? Will we wait another 100 years? How many more lives will be sacrificed?
This compelling video will show you why Death By Underride, though unnatural & preventable, still continues.
Trucking companies could demand trailers with side underride guards. Trailer manufacturers could supply trailers with side underride guards. Or the government could mandate side underride guards — ideally with the support of industry because a government law or regulation will place all manufacturers on a level playing field.
Families of underride victims and engineers appealed to trailer manufacturers to take the bull by the horn, embrace the Consensus Side Guard Standard, and move forward with developing and installing side underride guards ahead of government requirements.
Today, I was reflecting on the Side Guard Task Force meeting and a strategy for action going forward. As I was looking up information on an engineer from one of the manufacturers, whom I’d met several years ago, I noticed that the manufacturer is making plans to hire an engineering intern for the Summer of 2021. Beautiful! Brilliant! How about we show this young intern how engineers can save lives.
Imagine engineering students from universities around the nation spending the coming year doing internships or senior capstone projects at trailer manufacturing companies working alongside industry engineers on side underride guard development. Collaboration could take place and serve to more rapidly bring about the development and implementation of long-overdue, life-saving technology.
Note: The Side Guard Task Force meeting on February 26, 2021, was a follow-up to an earlier meeting. On April 17, 2020, over 40 people participated in a virtual meeting of a volunteer Underride Protection Committee’s “Side Guard Task Force.” This included two engineers from trailer manufacturers. As a follow-up, several subcommittees began to hold virtual meetings, including an Underride Engineering Subcommittee.
After listening to Andy Young interview Eric Hein about the loss of his son, Riley, in a side underride, participants viewed a photo memorial slideshow of some of the countless underride victims:

Some of the many individuals and organizations who have made contributions to the work on underride protection were celebrated in this Underride Hero Hall of Fame video:

On April 17, 2020, over 40 people participated in a virtual meeting of a volunteer Underride Protection Committee’s “Side Guard Task Force.” This included two engineers from trailer manufacturers. As a follow-up, several subcommittees began to hold virtual meetings, including an Underride Engineering Subcommittee.
The engineering subcommittee met at least monthly and sometimes every other week from May through November. At the outset, the VP of Engineering of one of the trailer manufacturers provided valuable input. Subcommittee members also participated in a Virtual Briefing for Senate Commerce Committee transportation staffers on August 19, 2020.
The goal of the Underride Engineering Subcommittee was to create a Consensus Side Guard Standard which would provide additional insight for the development of a side guard regulation and industry standard. Lengthy conversation and exchange of information has led this group to submit the following recommendation:
A side underride guard shall be considered to meet the performance standard if it is able to provide vehicle crash compatibility with a midsize car, to prevent intrusion into the occupant survival space, when it is struck at any location, at any angle, and at any speed up to and including 40 mph.
The subcommittee members are in agreement as to the details shaping this long-overdue standard, which they anticipate will lead to the saving of countless lives in the days and years to come. The following group of individuals participated in the Underride Engineering Subcommittee and are willing to continue to provide input.
NOTE: It should be mentioned that this standard has, in fact, been evaluated through research conducted by the Insurance Institute for Highway Safety when they crashed a car at 40 m.p.h. into the side of a tractor-trailer equipped with AngelWings side guards on August 29, 2017, during the Second Underride Roundtable at their Ruckersville, Virginia, testing facility.
There was no underride, no Passenger Compartment Intrusion (PCI), and the crash dummy data showed that it was survivable. In other words, this standard is not pie-in-the-sky; it has been proven that the Consensus Side Guard Standard is attainable.
