The National Highway Traffic Safety Administration (NHTSA) has announced the next four meetings of the Advisory Committee on Underride Protection (ACUP):
February 8, 12:30 – 4:30 p.m. ET; Topic: Rear Underride
March 13, 12:30 – 4:30 p.m. ET; Topic: Side Underride
April 24, 12:30 – 4:30 p.m. ET; Topic: Front Override
May 22, 12:30 – 4:30 p.m. ET; Topic: Underride Data
February 8 will be the third public meeting of the committee, which was established to provide advice and recommendations to the Secretary of Transportation on safety regulations to reduce underride crashes and fatalities relating to underride crashes.
On January 18, 2024, engineers and underride experts gathered via Zoom to expand the Consensus Side Guard Standard, developed by TEAM Underride in 2020, to specifically address the protection of All Road Users — that is, not only the occupants of passenger vehicles but, also, pedestrians, bicyclists, motorcyclists and other Vulnerable Road Users. In 2022, the term, Lateral Protection Device PLUS or LPD+, was coined*, and now the goal was to create language for a performance standard which such a device should meet.
We had gotten a good start on this process in December 2023. We continued that invigorating discussion and wordsmithing, and this is what we came up with to define the requirements for a Lateral Protection Device PLUS, or side impact guard, on a Commercial Motor Vehicle:
A side impact guard shall be considered to meet the performance standard if it is able to:
prevent intrusion into the occupant survival space of a mid-size vehicle when the Commercial Motor Vehicle (CMV) is struck at any location along its side, at any angle, and at any closing speed up to and including 40 mph, and
prevent a Vulnerable Road User (VRU) from passing underneath the CMV in an interaction along its side.
It is our hope that this process will ultimately result in collaborative action among diverse stakeholders, including government and industry, to develop a voluntary consensus standard which can guide rulemaking and catalyze timely, widespread adoption of underride protection on the sides of large vehicles as envisioned by the Department of Transportation in 1969. For the saving of many lives.
* The term LPD+ was suggested by Garrett Mattos on December 2, 2022, during a Zoom discussion among underride experts and advocates collaborating together as TEAM Underride to advance the implementation of engineering devices to prevent Death By Underride for All Road Users.
Deadly truck underride was at the top of the list for most listened to Frontline podcasts in 2023:
From the use of spyware on human rights activists and journalists to a surge in deadly crashes involving large trucks, The FRONTLINE Dispatch podcast shone a spotlight on some of 2023’s most compelling investigative reporting through in-depth, thought-provoking conversations with leading journalists and documentary filmmakers.

Underride Crash Memorials These are posts in memory of a few of the thousands of underride victims. The tip of the iceberg of senseless, preventable deaths. I will slowly be adding more.
What will it take to get UNDERRIDE on DOT Regulatory Agenda? We’ve been waiting 52+ years for DOT to move forward with side guards on large trucks — not to mention improving rear guard regulations and adding front underride protection. After numerous petitions, comprehensive underride rulemaking still has not made it the onto the DOT Unified Regulatory Agenda.
Collaborative Discussion of Side Guard Challenges on Specialty TrucksI was very pleased with the collaborative discussion which took place via Zoom on Monday, March 29, 2021, regarding the challenges of adding side guard safety technology to specialty trucks. Participants included primarily engineers and small companies who have been working on researching, designing, and/or marketing solutions to the underride problem. The meeting was also quietly observed by families of underride victims and administrative officials from the Federal Motor Carrier Safety Administration (FMCSA).
The March Madness of Competing Traffic Safety InterestsWhat is it like to compete for the attention of government leaders in order to get traction on the traffic safety problem which took your loved one’s life? Envision a press conference on a hot topic where a cacophony of reporters can be heard shouting out — vying for the opportunity to have their question be the one that gets answered.
Time for a National Traffic Safety OmbudsmanAlmost five years ago, after delivering a Vision Zero Petition to leaders in Washington, D.C., I realized that we need something more than a White House Vision Zero Task Force and a National Vision Zero Goal. We need a National Traffic Safety Ombudsman to be at the helm of a nationwide network of community traffic safety advocates. Someone who will have a place at the federal table — with the authority to take ongoing action on behalf of vulnerable victims of vehicle violence.
Engineers, Trucking Industry, & Victim Advocates Collaborate at Side Guard Task Force 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.
Should we be concerned about side guards getting hung up on railroad tracks?I keep hearing members of the trucking industry bring up the possibility of side guards on trailers getting hung-up on railroad tracks. They point to it as a reason to not require side guards on all new trucks. Is that a valid concern? And where is their documentation?
Transport Companies Provide Feedback on Side Guard Operational IssuesWe know that the trucking industry has expressed concern about potential operational issues which could occur when side guards are installed on large trucks. In order to address those concerns, we asked several trucking companies to give us feedback about their experience after installing side guards on their tractor-trailers.
Consensus Side Guard StandardOn 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.
FMCSA Proposed Rule For Inspection of Rear Underride Guards A red letter day: The Federal Motor Carrier Safety Administration (FMCSA) at long last has proposed a rule to add rear underride guards to Appendix G. What does that mean? It means that rear underride guards will be required to be in good condition in order to pass an annual vehicle inspection. Once the rule is actually issued.
Retrofit Solutions for Rear Impact Guards to Prevent Deadly UnderrideIt is to their credit that nine U.S. trailer manufacturers have improved their rear underride guard design to meet the IIHS TOUGHGuard standard and seven of them are putting it on all new trailers as Standard. What that means is that they have surpassed the current federal standard and have been crash tested to show that they are more likely to prevent underride and catastrophic Passenger Compartment Intrusion (PCI) — thereby more likely to save lives when passenger vehicles rear end tractor-trailers.
Save Lives by Lighting up Tractor-Trailers & Tanker TrucksTruck drivers can play an important role in making sure that the trailers which they haul are as visible as possible to other drivers on the road — especially at nighttime. On October 15, 2018, Leslie and Sophie Rosenberg lost their lives when they collided with the side of a tanker late at night.
Truck Driver Mistakes Don’t Excuse Industry & Government Negligence To Solve Underride ProblemThanksgiving Eve, another apparent underride victim lost her life: Though the truck driver may have made a mistake, not all the blame rests with him for a crash which might have had a different outcome with effective underride protection. Carriers, trailer manufacturers, DOT, & Congress can make these kinds of truck crashes more survivable.
A fully-guarded trailer hits the road – ready to STOP underride! Engineering ingenuity and a lot of hard work went into the research, development, and installation of this fully-guarded trailer system. This week, a small carrier in North Carolina became part of our pilot program. We are thankful that they have agreed to provide us feedback on this #SaferTruck as they drive it on the road to carry out their transport business.
On August 19, we hosted another Underride Staff Briefing — this time via Zoom. We are providing Congressional Offices with the PowerPoint pdf from that presentation, including comments from engineers with expertise in underride as well as underride families: Underride Briefing PowerPoint pdf (inc. links to resources & video)

RAMCUP.Roya, AnnaLeah & Mary Comprehensive Underride Protection.They paid the price:
Because the bottom of a truck is higher than the bumper of passenger vehicles, when there is a collision the smaller vehicle easily slides under the truck and the first point of impact is the windshield — resulting in underride and passenger compartment intrusion (PCI). Seatbelts, airbags, and car crumple zones do not function as intended in underride crashes — front, side, and rear — leaving passenger vehicle occupants vulnerable to life-threatening injuries.
This geometric mismatch has been misunderstood for decades. Reports on truck crashes generally focus on the cause of the crash and not what caused the deaths. So underride is undercounted. I know this from firsthand experience having been in a truck crash (but not in the part of the car which went under the truck) and lost two daughters because of underride (one of whom was not reported as such in DOT data).
In order to raise awareness and preserve the memories of underride victims — precious ones gone too soon — I have been writing memorial posts on what appear to me to be underride crashes. I am not a crash reconstructionist, and I do not have all the facts on these crashes; but underride should be investigated as a potential factor in truck crash injuries and deaths.
This is not an exhaustive list — merely the tip of the iceberg. But I hope that it serves to demonstrate the ongoing nature of a preventable public safety problem.

Yesterday, Jerry and I received a phone call from Aaron Kiefer, who shared with us the tragic news of the unexpected death that morning of Paul Hutson. Paul, after learning about the underride hazard, devoted many hours of his life to bringing about engineering solutions. First as an engineering student intern in 2015, and later as a volunteer after hours while working as a full-time engineer, Paul was an invaluable resource to Aaron Kiefer in his development work on prototypes for the RIG Retrofit (crash test seen below) and SafetySkirt.
Paul selflessly offered his engineering talent and skills to the mission of AnnaLeah & Mary for Truck Safety and TEAM Underride. He helped behind the scenes and on numerous crash test sites, including the Underride Crash Test Event in D.C. in 2019. He came to an Underride Roundtable, and he participated as an expert at one of our Underride Briefings for legislative staff on The Hill.
Why did Paul do this? We can no longer ask him this question, but I can only imagine that — like so many others — he understood the violence and severity of the underride problem and he loved to solve problems. This is how he described himself on LinkedIn:
Principal Engineer – Structural Analysis, Northrop Grumman · Full-time Working as a structural analysis engineer on Northrop Grumman’s Propulsion Systems team. My work focuses on the five-segment rocket boosters used on NASA’s Artemis, and the ground based strategic deterrent Sentinel.
Mechanical Engineer, Collision Safety Consulting, PLLC · Part-time Designed and analyzed a semi-trailer safety device that protects passenger vehicles during collision with a semi-trailer, preventing both side and rear underrides from occurring.My work included product design, drafting, analysis (FEA), and full-scale crash testing the system.
Just last week, an Australian engineer died. George Rechnitzer, whom Jerry and I had met early on in our mission to make truck crashes more survivable, contributed greatly to understanding and solving the underride problem. Of course, numerous other engineers have likewise passed away before seeing their contributions to underride research fully implemented to benefit road users. That includes Mark Roush from Vanguard Trailers, who held a side underride guard patent and who worked on Vanguard’s TOUGHGuard design. It also includes Rod Ehrlich, who among other accomplishments worked on a side underride guard design while an engineer at Wabash Trailers.
My Underride Hero Hall of Fame is full of well-known as well as unsung heroes, who have made important contributions to solving the underride problem:
Imagine what we could accomplish if the hard work of these engineers, who are no longer with us, were to be acknowledged and embraced by key members of the trucking industry, the National Highway Traffic Safety Administration, and the Advisory Committee on Underride Protection. Together, how many lives could we save? Let’s take the baton and finish the race.
However, after reading the many and varied comments on the YouTube video of the broadcast, I decided to respond in detail by posting my thoughts here. I hope that, no matter how much you know about underride, you’ll take some time to hear what I have to say:
Progress has been made in reducing underride deaths. But we’re not done yet; we’ve got a lot more work to do.
For example, seven trailer manufacturers are installing stronger rear underride guards as Standard on all new trailers. However, two trailer manufacturers, who have also designed a stronger rear underride guard, are merely offering it as an Option and are, in fact, still selling tens of thousands of new trailers every year with a too-weak rear underride guard — putting road users at risk of Death By Underride.
Not only that, despite the availability of Rear Impact Guard (RIG) retrofit solutions, millions of trailers on the road still pose a known unreasonable risk. It certainly doesn’t help that NHTSA recently issued a new RIG Rule but failed to require that these safety devices meet a technically feasible level of strength proven possible by nine manufacturers.
Families of underride victims gathered on September 14, 2023, in front of the U.S. Department of Transportation at 1200 New Jersey Ave SE in Washington, DC — with crash test cars from the Insurance Institute for Highway Safety 2017 side underride research in the background — to remember loved ones, who lost their lives due to truck underride.
The families rang a commemorative bell for over 750 victims, primarily from the last few years, and called upon the Department to re-evaluate publicly available data, end their decades of inaction, and issue strong underride regulations. Their message was this: Delay = Death.

The names, included in this solemn event, were taken from a combination of sources, including victims from families known to me and memorial posts on this website. In order to raise awareness and preserve the memories of underride victims — precious ones gone too soon — I have been writing memorial posts on what appear to me to be underride crashes, from daily Google Alerts which I receive on truck crashes. I am not a crash reconstructionist, and I do not have all the facts on these crashes; but underride should be investigated as a potential factor in truck crash injuries and deaths.
This is not an exhaustive list — merely the tip of the iceberg. But I hope that it serves to demonstrate the ongoing nature of a preventable public safety problem.

“Underride crashes, which occur when a car slides underneath the body of a truck, have tragically become all too common on our highways. These crashes are preventable. Underride guards on large trucks save lives. I urge @NHTSAgov to implement stronger protections without delay,” said Congresswoman Jan Schakowsky. “I would be remiss if I did not mention all the survivors and family members who are turning their personal tragedy into advocacy. We could not do this without you.”
A local photographer became part of the all-volunteer TEAM Underride — offering his skills to capture a day in the life of an underride crash test crew at the Raleigh Underride Crash Test Event on August 3 at the North Carolina State Highway Patrol training facility. Here’s a glimpse of that day from a photographer’s perspective: Team Underride Crash Test Event.
