More research on side underride has just been published by SAE International following a presentation by Garrett Mattos of the Friedman Research Center at a SAE Conference. Hopefully, the Department of Transportation now has enough research to make good on their March 19, 1969 intention to add underride protection to the sides of large vehicles.
A tractor-trailer, with and without side impact underride protection, was impacted by a passenger car and SUV under a range of impact conditions. Passenger vehicle intrusion metrics were calculated to provide an indication of relative risk for each impact condition. The results can support the development of side underride protection recommended practices. Protecting Passenger Vehicles from Side Underride with Heavy Trucks
Eight major trailer manufacturers have designed stronger rear underride guards to withstand a crash test at 35 mph all the way across the back of the trailer — earning them the TOUGHGuard Award from the Insurance Institute for Highway Safety (IIHS). This is significant because their previous designs — though meeting the current federal standard for rear guards — have been proven too weak and ineffective by IIHS.
There are about 300,000 new trailers sold every year. Some manufacturers are selling the stronger guard as Standard on all new trailers. Others are selling it as an Option, meaning that trailers may still be sold with guards known to be too weak to stop cars and save lives.
In addition, if we don’t retrofit the existing 11 million+ trailers with stronger guards — which will meet the TOUGHGuard criteria (plus side and rear underride protection) — it will be years before the entire fleet will be safer to drive around.
Fortunately, some of the trailer manufacturers have a retrofit kit for the rear guards, so that a trucking company could theoretically purchase kits to make their trucks safer. However, without a mandate to do so, I don’t imagine that will happen too quickly.
But I am encouraged by the work of Aaron Kiefer, a North Carolina crash reconstructionist who has seen so many underride tragedies that he decided to design some solutions on his own — primarily out of his own pocket and on his own time, with the support of his family who share their husband and dad with his life-saving project.
Just this weekend, Aaron installed the latest version of his Rear Reinforcement Attachment to a 53 foot trailer. Over the last five years, Aaron has been developing a design for two aluminum triangles, which are fastened to both sides of the trailer and then attached to both ends of the existing rear underride guard.
The latest version installed on September 15, 2019.
This reinforces the strength of the rear guard — improving its capability to stop a car and prevent underride. But it, also, serves as the point of attachment for Aaron’s side guard invention, the SafetySkirt — polyester webbing which can be combined with a side skirt to both save fuel and save lives.

You can see the SafetySkirt being tested at the D.C. Underride Crash Test Event on March 26, 2019:
We are looking forward to the day when Aaron’s SafetySkirt System can be tested at IIHS to prove its usefulness as an affordable, lightweight solution, which could theoretically be available as an option to retrofit any truck on the road with effective side and rear underride protection.
Aaron, like Perry Ponder who invented the AngelWing side guard, and countless other engineers, who should be given a green light to solve the underride problem, are amazing members of my Underride Hero Hall of Fame — along with my husband Jerry who has contributed a wealth of ideas in this underride advocacy journey.
Allen and Donna Smith, trucker advocates, host the Ask the Trucker Radio Talk Show. Underride was discussed on the show in March 2018 and again on April, 27, 2019. We appreciate their open mind and willingness to draw attention to this issue and foster open and honest conversation with truck drivers. Listen in here:
We strive for facts & truth rather than talking points. Truckers have valid concerns about underrides and we want to address them. Proponents of underrides also have legitimate concerns for supporting the Stop Underrrides Act. Let’s hear both sides.
Guests on the show:
Jerry and Marianne Karth and Lois Durso advocates for Underrides and have lost loved ones due to Underride crashes. These underride deaths were not the fault of either 4 wheeler. One was an improper truck lane change, the other was icy roads.

Perry Ponder, inventor of the AngelWing side guard, has made another great contribution in the pursuit of improved underride protection. Earlier this week, I saw that I had received a notification of a new public comment on the rear guard NPRM.
His letter begins with this comment:
As NHTSA moves at a glacial pace toward revising FMVSS 223 and 224, I’d like to point out an underride guard mode of failure I have observed while investigating a number of trailer and truck underride accidents.
I hope that Perry Ponder will be one of the members of the Committee On Underride Protection (COUP) which the STOP Underrides! Bill calls for in order to establish transparent, consistent, and ongoing communication and collaboration to help us more quickly end preventable Death By Underride.
On March 30, Jerry and I witnessed a crash test at 35 mph of a car into the side of a trailer — with an AngelWing side guard installed — at the Insurance Institute for Highway Safety (IIHS) Vehicle Research Center in Ruckersville, Virginia. The guard was successful in stopping the car from riding under the trailer, i.e., passenger occupants would have survived.
The next day, another car was crashed at 35 mph into the side of a trailer — with a side skirt but no side guard. The car went under the trailer. Occupants would not have survived.
See it for yourself because Seeing Is Believing:
This one may be tough to watch:
The IIHS released the news today:
Note this quote from David Zuby, IIHS Chief Research Officer:
“Our tests and research show that side underride guards have the potential to save lives,” says David Zuby, the Institute’s executive vice president and chief research officer.“We think a mandate for side underride guards on large trucks has merit, especially as crash deaths continue to rise on our roads.”
The wheels on a tractor and trailer offer some underride protection if a passenger vehicle were to strike them. With no side underride guard, only 28 percent of a 53-foot trailer’s length would be protected from underride. With the AngelWing side underride guard in place, 62 percent of the trailer’s length would be protected. Side underride guards can be retrofitted to existing semitrailers.
The IIHS also released data from their recent in-depth analysis of NHTSA FARS truck crash fatality information:

If this many people were dying from an automotive defect and we knew it and we knew how to fix it, would we stand by and let those deaths continue?! Maybe that is the wrong question to ask because those kinds of deadly defects have been neglected as well. But the point is,
What will we choose to do at this crossroads?
Continue to allow underride deaths?
OR
Act responsibly to prevent these tragedies?
This is not the first time we have witnessed successful prevention of deadly side underride:
Robert Martineau, President and CEO of Airflow Deflector, Inc., discusses the problem of side underride:
It’s one of the most devastating traffic accidents: A car slams into the side of a tractor-trailer and crashes underneath and where most of its many safety features like airbags and other sensors are rendered worthless. As a result, the top of the vehicle may be sheared off; in many cases, the occupants are fatally injured.
Perry Ponder, inventor of the AngelWing side underride protective device, explains to Jerry Karth how his side guard is installed and does its life-saving work.
NBC News received a letter from the Truck Trailer Manufacturers Association about the Today Show investigative report on Side Underride. After further investigation, NBC News added this to their article on the report:
Update and correction: After the publication of our story, we received a letter from the Truck Trailer Manufacturers Association (TTMA), which argues that our report overstated the simplicity of the side guard fix and that prototypes have been technical and commercial failures. TTMA made the same argument to NHTSA in a letter we referenced in our report, which you can read here. They also told us that TTMA has not made any political donations to lawmakers on the issue of side underrides, including to Senator Thune. In response to other points made by TTMA, we have updated our online report with TTMA’s response that guards in Europe are focused on protecting bicyclists and pedestrians, not automobiles and that NTSB said injuries and deaths “could” be reduced by side guards, instead of “would.” We also have updated campaign finance data, broken out donations from the trucking sector of the transportation industry, and corrected the period during which those donations were made.
I previously wrote about the TTMA’s May 13, 2016 letter to NHTSA about side guards. Read it here.
Despite the TTMA’s objections to the report, the fact remains that almost as many people die from side underride crashes each year as from rear underride crashes. And, furthermore, I have seen with my own eyes the difference that side guards can make in stopping deadly underride.
Will we let the technical and commercial failures of side guard prototypes in the past stop us from keeping at the task of solving this problem? I thank God for people like Aaron Kiefer and Perry Ponder who have kept at it until they successfully proved what human ingenuity could do to save lives.
Note: In fact, Europe’s side guard standards are designed to protect pedestrians and cyclists — which the U.S. should do, too! But Europe does not require the prevention of cars from underriding trucks. I have been in communication with a global automotive regulation specialist, and I hope that what happens here in the U.S. will have a ripple effect globally.
Great progress is being made in underride protection on the sides of large trucks in the month of January 2017. While Aaron Kiefer is preparing for a crash test of his innovative TrailerSafe System side/rear guard on January 20 in North Carolina, Airflow Deflector tested Perry Ponder’s Angel Wing side guard design in New York.
The Angel Wing crash test was declared a success: the side guard prevented the side of the trailer from going past the windshield thus promising protection from Passenger Compartment Intrusion (PCI). In other words, it is likely that, due to the side guard in combination with the crashworthiness of the car, no one would have been killed or seriously injured by the collision between the side of this truck and a smaller passenger vehicle.
Side underride is not a new problem. For too long, nothing has been done about it. Yet here are two unique and innovative solutions to protect us from deadly side underride. Two Life-Savers.
I count myself privileged to be cheering these innovative and compassionate engineers on in their important work which will save countless lives. Now, here’s to getting these marvelous inventions onto the trucks we all drive around each day. . .
