A woman in a motorized wheelchair was hit and killed Tuesday afternoon in Winter Springs, a spokesperson for the city told WESH 2. . .

Officials said they found the woman lying in the roadway, “deceased from what appeared to be injuries suffered from being struck by a semi-tractor-trailer.”

The woman was on the sidewalk when a semi heading east on SR-434 was attempting to make a right turn on Belle Avenue.

As the semi began to turn right onto Belle, the woman started to cross Belle and was hit by the trailer of the turning semi, thrown from the wheelchair and killed, officials said. Woman thrown from wheelchair, killed after being hit by semi making turn in Winter Springs

Colene Ruhl, Precious One Gone Too Soon

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. This is also true for Vulnerable Road Users, such as pedestrians, bicyclists, motorcyclists and wheelchair users, who can suffer catastrophic injuries when they collide with the unguarded side of a large truck.

Note: 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 could potentially 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. See Underride Crash Memorials posted here and at #STOPunderrides Tweets.

Critique of NHTSA-Contracted Elemance Rear Impact Guard Research

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

Secretary Duffy,

The Department of Transportation (DOT) engaged Elemance LLC in 2022 to evaluate three current designs of rear impact guards. Unfortunately, Elemance conducted Finite Element analysis of two obsolete rear underride guards that were not current designs at the time of the contract. In fact, both of those designs had been proven a decade earlier to be crash-deficient. The two manufacturers — Great Dane and Wabash — have developed designs with safer, stronger rear-guard designs. Elemance compounded that error by employing an erroneous definition of Passenger Compartment Intrusion. Elemance’s research findings, Heavy-Truck Rear-Impact-Guard Finite Element Simulation and Analysis, are flawed and backwards-looking rather than helpful to the Department and Congress in evaluating current and future rear underride guard performance and regulatory standards.

Please find attached a detailed critique by engineers who are well-acquainted with the underride problem and solutions. This is what the engineers concluded about the NHTSA-contracted research:

In view of the defects in the Elemance report, a follow up study should be commissioned to evaluate examples of current state of the art rear impact guards that have been in service since 2016 and 2017 respectively. The study should utilize the correct definition of PCI and more accurately assess injury risk.

The Department should act promptly to address the flaws in this federal research in order to fulfill its mission to reduce roadway injuries and deaths.

The Missing Piece of the Roadway Safety Puzzle: National Roadway Safety Advocate

Safety Advocacy, , ,

It was puzzling to me how very challenging it is to advance safety measures to save lives. Then I realized that there is a MISSING PIECE of the PUZZLE: there is no National Roadway Safety Advocate at the US Department of Transportation.

Put together this online jigsaw puzzle: https://jigex.com/NfTV3

Then make a comment online to Secretary Sean Duffy (at USDOT). Let him know that you want him to put a person to work as soon as possible who will be a dedicated resource to victims and their families – a National Roadway Safety Advocate.

DOT Is Asking For Input. Tell Them To Give Crash Victims a Voice

Safety Advocacy, , , , , , , , ,

When it comes to changes needed to make our roads safer, who cares more deeply than crash survivors or victim families? The Department of Transportation is asking for the public to submit their comments on what should be included in the 2026 Surface Transportation Reauthorization Bill; Secretary Duffy is looking for ideas to make our roads safer.

Let him know that you want victims to have a voice within the Department and that a means to do so has already been proposed by Senator Lujan and Congressman Cohen. The DOT Victim & Survivor Advocate Act would create a National Roadway Safety Advocate to serve as a voice for victims and survivors of roadway crashes and their families — ensuring their perspectives are considered in transportation safety policies.

I know from twelve years of road safety advocacy that this resource is extremely important but is not currently available to assist those who are keenly motivated to bring about change. Let Secretary Duffy know that you want him to put that plan into place.

Good News: Stoughton extends IIHS-award-winning underride protection to container shipping

Safety Advocacy, Truck Safety, , , , ,

Good news on underride protection: IIHS has given the TOUGHGUARD Award for rear impact underride protection on intermodal chassis trailers to Stoughton Trailers — the first trailer manufacturer to earn it and one of the largest chassis manufacturers in North America. Should this lead to speculations about what engineering ingenuity could actually produce — despite industry grumblings about the operational issues regarding underride protection, particularly at the sides of intermodal chassis trailers?

Underride guards that meet the Toughguard criteria are substantially more likely to withstand an impact, reducing the severity of the crash. Until now, only dry van, refrigerated and flatbed trailers have qualified. But with the growing importance of shipping containers in global trade, more and more freight is being transported using intermodal chassis.

Chassis-type trailers present a unique challenge when it comes to underride protection. The frame of a dry van, refrigerated or flatbed trailer extends across its entire wheelbase, supporting the underride guard for its full width. In contrast, an intermodal chassis is a ladderlike structure that lies between the trailer’s wheels to support the removable container.

For that reason, the underride guard required a completely new design. Instead of a vertical support attached to the trailer deck, the chassis guard features long, diagonal supports running from the guard’s outboard ends to the chassis rails. Stoughton Intermodal Chassis Earns Underride Guard Award

I’m grateful for Stoughton Trailers’ continued commitment to safety. Unfortunately, not every trailer manufacturer is equally safety-minded. And NHTSA has not shown an inclination to send a strong message to industry; in fact, they declined to include Stoughton’s dry van RIG solution in their regulatory analysis for a 2022 update of the rear guard rule. Decades of government and industry inaction means that there are still far too many (almost ALL of them) trucks on the road which do not have adequate underride protection.

Engineers know how to creatively solve problems. Give them a green light to SAVE LIVES!

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. . .

Certified Letters Alert Carriers of Underride Dangers, Liability & Solutions

Safety Advocacy, Truck Safety, , , , ,

The fact that truck and trailer designs can potentially allow underride when there are collisions with passenger vehicles has a long history of being misunderstood. With that in mind, on October 12, 2024, we sent letters to two lists of “100 top carriers” in North America via Certified Mail. We wanted their Boards and CEOs to be aware of the September 2024 $462 million verdict in a product liability lawsuit against a trailer manufacturer for failing to install a protective rear guard, leading to two fatalities — indicating that juries will not accept more of these preventable deaths.

“We hope the decision the jurors reached sends a clear message to the trucking and trailer industry and will finally force them to build safer trailers,” CVN noted, quoting plaintiff co-counsel Brian Winebright https://www.freightwaves.com/news/wabash-national-hit-with-462m-verdict-in-trailer-equipment-case

 We also encouraged trucking companies to take steps to protect road users and their bottom line by making sure that their fleets are equipped with Rear Impact Guards (RIGs) which qualify for the IIHS TOUGHGUARD Award and side impact guards that prevent side underride fatalities.

The mailing list for the 200 companies can be found here.

The Carrier Letter Template can be found here. 

A similar Certified Mail Letter went out to carriers in 2020. Relevant information is posted here.
