The guard didn’t break off AS the car went under the truck; the car went under BECAUSE the guard broke off!

Truck Safety, , , ,

I have read many news reports of truck crashes. It often strikes me how little the media, along with everyone else, understands the underride problem. Last night I read an article about a truck crash which happened in November in Dallas; it was a good example of this common misunderstanding of what an underride is.

A car was traveling northbound along Harry Hines Boulevard when it started coming up on a UPS truck at the Lombardy Lane stoplight. The 18-wheeler’s 53-foot trailer was empty at the time. However, the car’s driver did not stop and slammed into the back of the big rig. The UPS truck’s rear bumper broke as the car went underneath the trailer.   http://dfw.cbslocal.com/2017/11/13/car-slams-into-big-rig-dallas/

What the reporter apparently misunderstood was that the rear bumper did not break off as the car went underneath the trailer. No, the car went underneath the trailer because the bumper broke off!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! It was too weak — just like on the majority of the millions of trucks on the road today. Underride tragedies waiting to happen.

At first I was frustrated with the way underride gets reported (or rather does not get reported). But then I realized that this is a perfect example of the common misperception that something about the severity of the crash forces/dynamics itself is what leads to the car knocking off or bending the rear underride guard. In fact, it is the weak guard which gives way, fails, and bends or comes right off the trailer and then there is nothing to stop the car from going into the empty space under the truck.

Or, as Jerry Karth says, to put it another way, “the guard failed to perform as it was designed to do.” (As this IIHS video so thoroughly explains.)

In contrast, see what happens when there is an effective underride protective device to cause the car to bounce off the guard (deflects the crash forces) and allows the car’s crush zone, airbags, and seat belts to work like they were supposed to upon collision.

The car is damaged, but the passengers are safe:

I hope this helps people to better understand the dynamics of an underride crash.

In underride, first point of contact with the truck is your windshield, then your head.

Truck Safety, , , , , , ,
Just yesterday, as Isaac and I were nearing the end of our road trip from the Atlantic coast to the Pacific coast, Isaac said, “Maybe next time we make this trip, the trucks will look different and be a whole lot safer.”
 
I am very grateful that we are seeing significant progress in underride protection. And the gathering of almost 100 people at the Insurance Institute for Highway Safety on August 29 has helped to continue the work of many people to make that possible.
 
Dawn King, president of the Truck Safety Coalition, with photos and video, describes the recent Underride Roundtable at the IIHS and why it was so important. Because a truck underride crash can happen to anyone. To AnnaLeah & Mary. To you or somebody you care about.
 
As Dawn explained,
“When you slide under a trailer your car’s safety features aren’t activated because your front bumper doesn’t hit anything. The first part of your car to come in contact with the trailer is your windshield. And then your head.”
 
“Someday soon the results of lots of peoples dreams will come to fruition. And it will happen because people from all walks of life sat down and talked. Trailer manufacturers, truck companies, safety experts, devastated families, government officials.”
 
Just what I’ve been hoping for:
 
After our crash, Jerry wrote to numerous trailer manufacturing companies asking them to voluntarily step up their underride guard standards. We got some positive response and stirred up interest in companies — to whom he also wrote — who purchase trailers–enlightening them as well. One of the manufacturers, Great Dane, invited us to tour their Research & Design Center on June 25, 2014.
 
Afterwards, I posted this: Underride Guards: Can we “sit down at the table together” and work this out? with this video: “Underride Guards: Now What?” to summarize what I saw as the frustrating lack of progress on improving underride guards and the seeming lack of communication among the various responsible parties with the authority to do something about it.
 
Of course, we weren’t the only ones frustrated with the inaction on what seems to be a drastically-needed change. When we took our 11,000+ signed petitions to DC in May 2014, we met with the Insurance Institute for Highway Safety (IIHS). At that time, they put it like this: “It is safer to run into a brick wall than into the back of a truck.” Yet, seemingly, nothing was being done about it. So we helped to organize the first and then the second Underride Roundtable.
 
Now something is being done about it.
 
We don’t have to let this continue to happen. We can do something to prevent deadly truck underride crashes. I’ve put together some ways that YOU, too, can help make trucks safer: https://annaleahmary.com/how-you-can-help/

Needed for an Underride Crash Test: Beat-up 53′ Box Trailer & a Chevy Malibu

Safety Advocacy, Truck Safety, , ,

Aaron Kiefer is making plans to do a preliminary crash test of his innovative side/rear underride protection system – before taking it to the Underride Roundtable at the IIHS on May 5, 2016.

He has asked us to be on the lookout for two things which he needs for the crash test:

  1. a used 53′ box trailer with its rear underride guard and its landing gear intact (not bent or rusted) and
  2. an older model Chevy Malibu–from the year 2000 or younger.

If you have either one of those which you could donate (or sell for almost nothing) to make this important crash happen, please email me at marianne@annaleahmary.com.

Here is more information about Aaron’s hard work to make trucks safer to be around:

Aaron plans on using the crash test results to refine his design and make it as effective as possible. Please spread the word about this need. Thank you.
