Safety Advocacy, Truck Safety, , , , , ,

The FMCSA and the Institute for Transportation Research & Education at North Carolina State co-hosted of the Commercial Motor Vehicle 2026 Safety Summit in Raleigh, North Carolina August 10-11, 2026. The organizers invited AnnaLeah & Mary for Truck Safety (ALMFTS) to arrange an underride crash testing demonstration by Aaron Kiefer (Collision Safety Consulting) and a volunteer TEAM Underride Crash Test Crew — as part of the Technology Showcase held at the NC State Highway Patrol training facility on August 11.

Educational resources available to participants at the STOP Underrides/Collision Safety Consulting booth in the Exhibit Hall and the Technology Showcase are provided here digitally:

Here is Video Footage from the Crash Tests:

  • Crash test into the side of a trailer WITH a side impact/underride guard at 39 mph
  • Crash test into the side of a trailer WITHOUT a side impact/underride guard at 40 mph

Media Coverage:

We know this unique opportunity to showcase the technical feasibility of underride protection could not have been accomplished without the commitment to safety evidenced by so many people. We are grateful to the individuals and organizations whose donations made this demonstration of life-saving technology possible — including gifts given in memory of several underride victims, as well as an engineer who made significant contributions to underride research. Additionally, we are thankful to the 25 members of the TEAM Underride Crash Test Crew, who volunteered their time and skills from around the country, as well as the help and resources from the NC State Highway Patrol, AWP Safety, and the Garner Fire Department.

WHP said troopers arrived to find a commercial motor vehicle vehicle had been struck head-on by a Chevy pickup truck. . .

The driver of the Chevy pick up, identified as Duane Derrick, 40, of Logan, Utah, died on scene. The driver of the commercial motor vehicle was transported to the hospital, was treated and released. Pickup driver going wrong way killed after head-on crash with semi truck in Wyoming

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. 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.

“Georgia looks to police to decide whether to start tracking deadly underride crashes”

Safety Advocacy, Truck Safety, , , , , ,

Proving that underride protection can save lives is not enough to convince federal regulators that underride mandates should be issued. The regulatory process requires that a rule be cost effective. There are many factors which should go into a cost benefit analysis equation. Unfortunately, we are aware of a multitude of flaws in this process and that includes excluding certain categories of underride victims:

  • Vulnerable Road Users (pedestrians, motorcyclists, and bicyclists) were not included in the 2023 Side Impact Guard ANPRM (See Senior Agency Officials Suppressed Side Guard Research — Impacting Regulatory Analysis);
  • victims of crashes where the posted speed limit is above 40 mph (not taking into account Delta-V forces in collisions);
  • victims of crashes which involve multiple vehicles (NHTSA only includes two-vehicle crashes in their regulatory analysis!);
  • as well as overestimating the weight of guards, not counting the fuel savings of side guards installed in conjunction with side skirts, or ignoring the cost to industry of lawsuits for preventable fatalities.

Another problem is the undercounting of underride fatalities, as we have previously documented, Joshua Brown/Tesla Side Underride Crash Coded as “No Underride” in FARS Data, and as described by Safety Research Strategies, GAO Concludes Underride is Underreported, Duh. In fact, very few states even have a checkbox for underride on their official state crash report form, as reported by the Institute for Safer Trucking in 2022:

A Georgia 11Alive investigative report continues to address that problem and is watching to see whether Georgia will add an underride checkbox to their state crash report form, Georgia looks to police to decide whether to start tracking deadly underride crashes:

Kaizen and Underride Protection: A New Industry Approach

Uncategorized, , , ,

What is the industry’s approach to underride protection? Is it anything like the Japanese attitude of Kaizen? This blogpost caught my attention:

I am reminded of a Japanese word: Kaizen. I read a book once that discussed the difference between the American mindset and the Japanese mindset – explaining that Kaizen is a Japanese word meaning “improvement or change for the better”. Kaizen is defined as a continuous effort by each and every employee… to ensure that there’s continual improvement. The book suggested the American mindset is to build something, work hard at it, step back, admire it, and then move on. The Kaizen mindset is to continue to improve what was built. . . This isn’t about perfectionism. The perfectionist mindset is fixated on what is wrong. The improvement mindset is fixated on what we can make better.

If that was our mindset in the United States, what might we hope to see in underride protection progress? How many more lives might be saved?

What’s New In Underride?

Safety Advocacy, Truck Safety, ,

There’s nothing new about underride. Despite the fact that it has taken loved ones from us for decades, bringing an end to preventable underride continues to be an uphill battle. We fight on.

Here are some recent instances of underride getting media coverage:

And, by the way, in case you missed it, here are videos from crash testing of collisions between bicyclists and tractor-trailers — conducted by Aaron Kiefer in Raleigh at the North Carolina State Highway Patrol training facility on September 13, 2024. . .

Advisory Committee on Underride Protection Reports to Congress & DOT Secretary

Safety Advocacy, Truck Safety, , , , , , , ,

On June 28, 2024, the Advisory Committee on Underride Protection (ACUP) completed a scathing critique of the Department of Transportation. In a 410-page report, it documented a long history of agency reluctance to regulate the trucking industry’s safety practices, exposed allegations of misconduct by senior officials, and called for the reversal of recent rulemaking that the committee believed made “no substantial progress” to improving public safety.

In its Biennial Report, commissioned by Congress in the Infrastructure Investment and Jobs Act of 2021, the committee contended that fatalities from underride crashes, in which large commercial trucks cause severe injuries to occupants of passenger vehicles, as well as pedestrians, bicyclists or motorcyclists, are largely preventable. But the committee found that, for over 50 years, the Department has not required manufacturers to install guards under the open sides of trailers, due to pressure from the industry.

The report exposed allegations from a whistleblower of serious misconduct. According to a former project manager at the Department in the agency that enforces rules for the trucking industry, senior Department officials in the Trump administration suppressed taxpayer-funded research into the cost-effectiveness of regulations requiring side guards on trucks. Trucking company lobbyists reportedly were angered by the research findings and pressed the Department to alter them. Officials in the Biden administration commenced a rulemaking process that ignored the key findings of the suppressed research. The report called upon the Biden administration to reverse course and start the rulemaking process over again, this time by counting the benefits it previously ignored. Advocates have asked the Inspector General to investigate.

Many of the ACUP’s critiques and recommendations were adopted over the objections of the trucking industry, which lacked the ability to veto the committee’s actions. They published their dissent in a minority report authored by the CEO of Utility Trailer Manufacturing Corporation, which recently was found negligent for the fiery death of a 16 year-old boy in a side underride crash. Utility’s share of the punitive damages was $18.9 million.

The committee, which was composed of engineers, emergency medical professionals, victims, safety advocates, law enforcement, and the trucking industry, sent its Report via NHTSA to Congress and the Secretary of Transportation on July 2, 2024. 

Below are links to the complete ACUP Biennial Report, the Majority Report, a Minority Report, and Appendices, including the statements of concurrence or dissent from ACUP members:
