NTSB Preliminary Report: Box Truck Overrode Van Killing Eight

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

The newly-released NTSB preliminary report describes June 3, 2019, Mississippi box truck/van crash with 8 fatalities: right front of the truck hit the right front of the van head-on. The truck OVERRODE the front of the van & penetrated the passenger compartment. Deadly PCI (Passenger Compartment Intrusion) occurred.

The driver of the van sat in a part of the van which did not go under the truck — no PCI (just like me). He walked away with minor injuries. The eight other van occupants all suffered fatal injuries.

Read it here. NTSB Preliminary Report, July 24, 2019: https://www.ntsb.gov/investigations/AccidentReports/Pages/HWY19FH009-preliminary-report.aspx

On October 21, 2010, the NTSB issue a Truck Underride Safety Recommendation based upon the investigation of a 2009 crash in which a truck overrode 3 cars and 10 people died as a result. The Recommendation reads like this:

Since 2003, European Union countries have required front underride protection systems on all newly manufactured heavy-goods vehicles, which indicates that such a standard is feasible. The NTSB concludes that collisions between passenger vehicles and the front of single-unit trucks or tractor-trailers are common types of crashes that result in fatalities, and front underride contributes to crash severity. The NTSB therefore reiterates its prior recommendations that NHTSA. . . require all newly manufactured trucks with gross vehicle weight ratings over 10,000 pounds to be equipped with front underride protection systems. . .

That was 9 years ago. Tell me, how many people could still be alive today had NHTSA acted upon that safety recommendation? Congress, I’ll say it again: the ball is in your court. Will you act decisively to STOP all forms of truck underride? Front, side, rear, tractor-trailer, single-unit truck, passenger vehicle, pedestrian, cyclist, motorcyclist.

Another Tesla Side Underride Tragedy Points to Need for Truck Side Guard Mandate

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

Late yesterday afternoon, I heard the news that another man has lost his life when his Tesla went under the side of a tractor trailer in Florida. No matter how it actually came about, doesn’t it seem tragic that we didn’t learn our lesson from Joshua Brown’s tragic death going under the side of a tractor trailer in a Tesla in May 2016?

Earlier today, a Tesla Model 3 owner died in a tragic accident with a semi truck. The Model 3 went under the truck’s trailer resulting “in the roof being sheared off as it passed underneath,” which is known as a “side underride” accident. Tesla Model 3 driver again dies in crash with trailer, Autopilot not yet ruled out

NTSB is sending a team to investigate this crash

Earlier this week, I wrote about the disturbing documentation that current Automatic Emergency Braking (AEB) technology on passenger vehicles is not reliably detecting large trucks: “AEB that reliably detects trucks could prevent underride crashes.” Meanwhile, what should we do? Yet, many of the voices opposing the STOP Underrides! Bill point to Collision Avoidance technology as the better route to prevent underride crashes.

Clearly, collision avoidance technology is not ready to prevent truck underride tragedies at this point in time. In contrast, comprehensive underride protection technology is ready to go — awaiting a mandate to get the ball rolling to save lives.

Here are two practical, viable solutions offered by engineers to prevent the gruesome, deadly passenger compartment intrusion (PCI) which occurs with side underride:

We cannot wait for the trucking industry to handle it themselves and the automotive industry is not prepared to prevent collision with large vehicles. Congress should feel proud to be the ones to make sure that this happens. Unless they want people to die!

D. C. Underride Crash Test, March 26, 2019

From the May 2016, Joshua Brown Tesla side underride crash: Witnesses reveal new details behind deadly Tesla accident in Florida

The police report indicated that Brown’s Model S collided with a tractor trailer that was perpendicular to it and continued to travel underneath it after having its windshield and roof sheared off. Because the vehicle was in Autopilot at the time, the vehicle continued to travel before veering off the road, careening through two fences, and finally coming to a rest after striking a utility pole approximately 100 feet south of the road.

Tesla released a statement on their blog:

“What we know is that the vehicle was on a divided highway with Autopilot engaged when a tractor trailer drove across the highway perpendicular to the Model S. Neither Autopilot nor the driver noticed the white side of the tractor trailer against a brightly lit sky, so the brake was not applied. The high ride height of the trailer combined with its positioning across the road and the extremely rare circumstances of the impact caused the Model S to pass under the trailer, with the bottom of the trailer impacting the windshield of the Model S.”

By the way, these are not “extremely rare circumstances.” Hundreds of vehicles collide with the sides of large trucks every year. Furthermore, both of these crashes clearly involved side underride. Why is this not being acknowledged and addressed?

Road Users Should Have the Right to Life: STOP Underrides!

Truck Safety, ,

I don’t know the exact fatality rate for people who experience Passenger Compartment Intrusion (PCI) when their passenger vehicle collides with a truck. But I imagine that it is close to 100%. After all, PCI means that the truck comes into your survival space. When a truck hits your body, what do you think is going to happen? You don’t stand a chance of survival, that’s what!

So, if there is technology which can prevent PCI, don’t you think that we should put it on large trucks? Don’t you think that road users should have the right to life?

STOP Underrides!

 

Another Successful TrailerGuard System Safety Skirt Crash Test : No Passenger Compartment Intrusion

Truck Safety, , , , , , ,

On Saturday, June 2, 2018, Aaron Kiefer’s volunteer crew of crash testers, conducted another round of crash testing with his TrailerGuard System consisting of a polyester webbing Safety Skirt connected to his aluminum Rear Reinforcement Attachment (which strengthens the existing rear underride guard).

Crash Test #1 showed some Passenger Compartment Intrusion (PCI), which means the people in the car would have been injured. Analysis of the results showed that the webbing was likely too low and not able to catch the car.

Crash Test #2, on the other hand, was very successful: no PCI. The car was damaged from the collision but did not go under the trailer and rebounded back. 35 mph Delta-V force, 31 mph impact speed

Aerial view from a drone:

Q. What does it mean that the air bags did not deploy?

A. The acceleration was low enough that the car decided that it didn’t need them. So the crash pulse was “long” due to the flexibility/energy absorbing of the webbing. According to the air bag control module report, the car deployed the driver seat and passenger seat belt pretensioners. However, the severity of the crash was judged below the threshold to require the frontal air bags. This is due to the fact that the deceleration was achieved over a long duration (over 200 ms) and that the decleration rate was low.
Q. So, how would occupants have fared?
A. The occupants would have been fine in this 30+ mph collision since PCI was avoided and the energy was absorbed by the webbing and the vehicle structure. the threshold for air bag deployment of a vehicle of this type striking a solid object is 10-15 mph.
Crash testing — especially without the backing of corporate R&D resources — is time-consuming but well worth the effort. Imagine where we would be in terms of preventing devastating truck underride if we all collaborated to get the job done!

A real-life crash between a semi-trailer & 2 cars shows the life & death difference which underride makes.

Truck Safety, , ,

A real life crash, where two cars collided with a semi-trailer, occurred in the Chicago area on October 16, 2017. One driver died; the other driver survived.

The 38-year-old driver of the Jaguar and the 27-year-old driver of the semi-tractor were each transported to area hospitals with non-life threatening injuries. The driver of the Envoy was pronounced deceased at the scene. 2 Dead, 1 Critically Injured in Aurora Crash Involving Semi

I don’t have proof yet, but it appears to me that the driver who survived may have done so because his car (the white Jaguar) hit the trailer tires, which activated the crush zone of the car and prevented underride ( or Passenger Compartment Intrusion = PCI). The driver of the other car was not so fortunate, the first point of impact was probably in his occupant space.

Exposing the Truth about the Truck Underride Conspiracy of Silence

Safety Advocacy, Truck Safety, , , ,

You cannot begin to imagine the riotous cacophony of emotions ricocheting about within this mother’s heart right now. Pain. Grief. Anger. Frustration. Outrage. Heartache.

These last few days, Lois and I have been on a journey together which has taken unexpected turns. After driving cross-country with my son to help him get settled in his new home in Santa Cruz, l took a red-eye flight to Chicago where Lois picked me up from the O’Hare airport.

Our original plan was to get on the highway and head for a cottage in Michigan. But it seemed good to us both to take this opportunity for Lois to give me a glimpse of her daughter Roya — the house where she grew up, a favorite restaurant, a school and church, her grandpa and the home he built, and finally her final resting place here on this earth.

It was a very good and a very hard thing for the two of us to do. And then we headed for my old stomping grounds.

We had made plans to spend a few days at a cottage on Lake Michigan where Jerry and I have created many memories. He and I discovered it one year on a getaway and thereafter brought our kids for many fun family times. It was also where we stayed with our nine children and their families when we returned North for my 90 year-old dad’s funeral in 2011. Twelve year-old Mary took over 600 photos on her hand-me-down camera that trip.

Perhaps you can imagine what it was like to arrive at a place so full of wonderful memories of AnnaLeah and Mary. Bittersweet. Heart-wrenching.

We enjoyed a beautiful sunset over the Lake that evening and contemplated our next steps in getting the Roya, AnnaLeah and Mary Comprehensive Underride Protection Act of 2017 introduced and passed as we tended a marvelous beach campfire.

The next morning, after sighting a rainbow on the Lake’s horizon, we set out for a local bagel shop to take advantage of their Wi-Fi. It was time to get down to business and compile a list of underride research which has been done over the years.

We had previously put together a list of underride recommendations and reports for the senator who intends to introduce the bill. Now we were responding to a request from her staff to add any additional underride research which we could find so that they could share it with Republican Offices in hopes of persuading them to jump on board with her in leading the way with this life-preserving legislation.

History of Underride Research & Reports: 1896 to 2017

In summary, this legislation is so vitally important because — all too often — it is not the collision of a car with a truck which is responsible for an ensuing tragedy but the lack of adequate underride protection. This results in a second collision where the truck collides with the passengers in the car and what is known as Passenger Compartment Intrusion (PCI) which occurs with truck underride.

The day before, we had updated Jerry and asked him to look for underride patents online. I knew of a couple in particular which we had already discovered in our unwelcome truck safety advocacy journey. What he then uncovered was beyond belief.

Jerry sent us a link to a U.S. patent for a side underride device invented in 1913. What?! That was before my 90 year-old father, who has been gone for six years, was born. Over a century ago!

But that’s not all! That patent from 1913 has been cited by 26 more recent patents — ones filed by engineers working on their own ideas for solving the problem of defective truck design which allows pedestrians, cyclists, motorcycles, and passenger vehicles to ride under the side of commercial motor vehicles. Unbelievable!

As if that were not enough to cause outrage to well up, we made another discovery as we began work on updating the research list. Jerry had also sent a link to an 1896 patent for a side underride device for streetcars. Again, this patent has been cited by numerous other patents for underride protection.

In the end, we were able to compile an extensive list of underride research, reports, and recommendations on front, side, and rear underride which provides incriminating evidence of an apparent conspiracy of silence. The negligence on the part of the trucking industry and the federal government to take the initiative to do whatever is necessary in order to protect the citizens of this country from a known deadly defect is appalling.

They can no longer cling to an excuse of ignorance. They have had more than enough time to put their heads together and come up with viable solutions.

The blood of countless underride victims has been unnecessarily shed. Our precious daughters have paid the price.

Whereas it is clear that there have been many individuals who have put forth effort to solve the underride problem, the overall inaction, on the part of the industry and government, and their refusal to take responsibility for effective collaboration to find a solution has taken its toll on American families. When will this behind-closed-doors conspiracy of silence end? Very soon, I hope! In fact, we have seen significant progress in recent years — although too little and too late to save our daughters.

I know that tomorrow, as Lois and I visit the cemetery where AnnaLeah and Mary saw their grandpa buried less than two years before we buried them close by, l will weep bitter tears. I only hope that our combined efforts will be fruitful and turn the tide.

I have often shared a photo of AnnaLeah and Mary with their arms raised in joyous victory. Yesterday, l was able, for the first time, to visit the luge victors’ stand in Muskegon State Park’s winter sports complex where that photo was taken. It broke my heart to see it empty and know that they will never be able to stand there again.

I look forward to the day when I can share their victory photo once more with the world because a step will have been taken to end this travesty once and for all. Mary will get her wish to be famous somehow.

May it be so. To God be the glory for orchestrating this difficult and long-time-in-coming strategy to end preventable underride tragedies.
