What is Front Underride Protection? (Find out on April 17)

Truck Impact Guards = Underride Protection

“As a. . . result of Utility Trailer’s negligence. . . Riley Hein LOST A CHANCE AT A BETTER OUTCOME”

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

According to a WUSA9 Investigative Report on Underride, court documents show, “As a direct, legal, and proximate result of Utility Trailer’s negligence, Plaintiffs’ decedent Riley Hein LOST A CHANCE AT A BETTER OUTCOME when instead of simply colliding with the semitrailer, his car became trapped underneath the semitrailer, resulting in a fire and directly leading to his death.”

That’s what the #STOPunderrides Bill is all about!  If passed, this legislation will give motorists and vulnerable road users A CHANCE AT A BETTER OUTCOME when they have the misfortune of colliding with a truck. Effective underride protection will prevent underride and enable the car’s crashworthy safety features, like the crumple zone, airbags, and seat belt tensioners, to do their job and protect the car’s occupants from deadly injuries.

This includes not only SIDE underrides but also those collisions that occur at the FRONT and the REAR of trucks. A few weeks ago, I obtained a FARS data report from NHTSA (DOT) for “reported” underride deaths during 1994-2017. It clearly shows that the number of reported underride deaths did not significantly decrease after a federal standard for rear underride guards was implemented in 1998.

NHTSA Fatality Analysis Reporting System (FARS): Underride Deaths, 1994-2017

Apparently, neither NHTSA nor the trucking industry bothered to make it a priority to look at those statistics and ask some hard but important questions, “Why are people continuing to die under trucks?” and “What can we do about it?”

In fact, just the opposite apparently occurred as evidenced by court documents which reveal that the trucking industry deliberately acted to protect themselves from being forced to add underride protection to their trucks. The TTMA (Truck Trailer Manufacturers Association) did not do this alone; the ATA (American Trucking Associations) played their part as well.

The question is: Where do we go from here? Congress, I’d say that the ball is definitely in your court.

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.

Overlooked Vulnerabilities in Truck Crashes: Damage to Steering Mechanism & Fuel Tank

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

Being a passionate advocate for making truck crashes more survivable, I signed up for Google Alerts on truck crashes. Every night I get an email notifying me of truck crashes across the country. Mostly I look for evidence of underride. But I have noticed the frequency of truck crashes that involve fire. Why is that?

Last fall, I looked further into the problem of front override/underride of trucks over passenger vehicles — either in head-on collisions or when trucks rear-end passenger vehicles. What I found was that many countries have front underride protection standards to improve the outcome in such crashes — including Europe, Australia, India, and Japan.

The front underride/override protection (FUP) protects the passenger vehicle occupants. However, it also protects the truck’s components from damage — including the steering mechanism, which means a truck driver will be more likely to maintain control in a collision. Additionally, underride protection can potentially prevent contact with a fuel tank and thus prevent a fire from starting.

NTSB Recommended FRONT OVERRIDE PROTECTION In 2010

after Truck OVERRODE 3 vehicles

Note the mention of fire and damage to the steering mechanism related to an underride crash in this research study, REVIEW OF TRUCK SAFETY: STAGE 1: FRONTAL, SIDE AND REAR UNDERRUN PROTECTION

Offset front underrun in head on crashes where the light vehicle is likely to collide with
the steer axle and compromise the heavy vehicles steering, and/or the underrun leads to
heavy intrusion of the cabin space by the heavy vehicle structure. Front underrun in truck into car crashes where the underrun can:
• rotate the light vehicle downwards and lead to the heavy vehicle running over the light
vehicle with catastrophic results;
• push the petrol tank down and lead to fire when the truck impacts the rear of the light

vehicle (p.4).

Where there was the ability for the truck to overrun the car bumper bar, the effect would be to compromise the cars energy absorption and increase the likelihood of intrusions into the cabin space. A further effect is that the rear of the car is pushed down and so there is an increased likelihood of fuel tank ruptures and of sparks being generated by steel contact with the road surface and hence significant increases in the risk of fire.  Hence overrun would be likely to increase the chance of fatalities in these crashes. (p.31)

Watch the rear of the car being pushed down in this side underride crash test:

The protection for the components of the truck are noted in this video of Volvo Front Underrun Protection System crash testing (starting at around 44 sec.):

So, tell me again why there is opposition and lack of action in the U.S. to mandate and install comprehensive underride protection — including Front Underride Protection (FUP). We are at a fork in the road: we can continue to let people die horrific underride deaths OR we can act decisively to mandate and move forward with comprehensive underride protection.

Myth: Significant differences in vehicle mass responsible for truck crash severity. #STOPunderrides

Truck Safety, , , , , , , ,

Two days ago, I found an Insurance Institute for Highway Safety (IIHS) Status Report from August 26, 1989. It had two articles about front underride protection which clearly demonstrated the benefit of installing that kind of technology on large trucks to reduce the severity of collision injuries.

“Front End, Energy-Absorbing Truck Guards Reduce the Risks for Motorists”, 8/26/89, IIHS Status Report

Here’s another report which I found the next day. It is a NTSB Safety Recommendation from May 8, 2006, which clearly explains the benefits of front underride protection. Thirteen years ago. And I find myself to be the only one in the country talking about this at any level of insistence that we do something about this. Now.

https://www.ntsb.gov/…/safety-recs/recletters/H06_16.pdf

I found it interesting that NHTSA stated in June 2000 that, “the common belief is that not much can be done to diminish the consequences of crashes between smaller vehicles and large trucks because of the significant differences in vehicle mass.

[I know this to be a MYTH both because I know that underride protection can significantly change the outcome and because I am a truck crash survivor of a horrific crash due to the fact that the truck did not come into my part of the car.]

“However, research has shown that geometric height differences and a lack of forgiving front truck structures CAN be modified to help reduce heavy truck aggressivity and to mitigate the severity of these types of accidents. Examples of these modifications, often referred to as ‘front underride protection systems’–which can result in reduced intrusion or occupant injury–include energy-absorbing front structures to offset the weight differences between two impacting vehicles, as well as bumpers designed to deflect the impacted vehicle away from the front of the truck, thereby reducing the total change in velocity of the smaller vehicle.”

This added information stirs up anger in me at what could have been done well before our crash — in which a truck hit us (front underride protection) and in which we collided with the back of a second trailer (rear underride protection). Fortunately, it also stirs up in me renewed energy and zeal to bring down the walls of Jericho and an end to this senseless loss of lives.

Every evening, I receive an email notification from Google Alert letting me know about recent truck crashes. Cheery, right? Many of them are frontal, head-on crashes between a car and a truck — or crashes when trucks rear-end cars, too. I know from research that Front Underride Protection (FUP) on trucks could reduce the severity of these crashes.

So when I read about one more of those in tonight’s Alert, I decided to do some more searching online about how FUP might help to prevent the fiery crashes which I frequently read about. One thing I found, that I had not read in the past, was a Status Report from the Insurance Institute for Highway Safety describing the benefits of FUP to reduce frontal crash severity. It was published on August 26, 1989 — thirty years ago.

Read it for yourself:  IIHS Status Report on Front Underride Protection August 26 1989

Now, tell me again why we don’t have FUP on trucks in the United States (though many other countries do). I’m waiting. . .

The chart below shows that NHTSA has recorded front underride deaths for decades (although it is known to be greatly underreported). Yet, they have done nothing to mandate technology which could prevent these deaths.

In 2002, the trucking industry predicted that there would be front underride regulations by 2006 (dubbed frontal aggressivity). Yet, they have done nothing to make sure that their trucks are as safe as possible around the traveling public.

@VolvoTrucksNA Why would you install safety equipment on your trucks in some countries but not others?

Truck Safety, , , , , , ,
Why would a major semi-truck manufacturer, Volvo Trucks, install FRONT UNDERRIDE PROTECTION [FUP] — safety equipment which could prevent catastrophic injuries and unimaginable deaths — on their trucks in some countries (Europe and Australia) but leave it off in other countries (North America)? Any guesses?
 
 
I would like to talk to their CEO and/or President and find out if they are aware of this situation.

Previous Front Underride Posts

A Road to Zero Coalition quarterly meeting was held on March 20, 2018, at the National Transportation Safety Board Conference Center in Washington, DC. The topic was Commercial Vehicles, from Safe Systems to Technology Innovations. (View the March 20 meeting agenda.)

The speakers and panelists at the Road to Zero Coalition spent the morning talking about Commercial Motor Vehicle Safety. Not one word was mentioned about underride until the end of the panel when the Safety VP of Schneider Trucking, Tom DeSalvio,  mentioned that they are looking at using the improved rear bumper (on new trailers). I think that they have something like 56,000 trucks in their fleet. I could be wrong.

When I asked him if they would retrofit existing trucks he talked about looking at the fleet and what ones would be turning over. I assume by that that he meant when they would get rid of old trailers and purchase new. Not retrofit existing.

I asked Skip Yeagel, Volvo Trucks, about when would Volvo put Front Underride Protection (FUP) on their trucks [in the United States] or does he think that it would take a federal mandate for them to do so. He said that he couldn’t really say but he figured that it would probably take a mandate.

I just found this pdf from the expert from the European Commission. . . a draft amendment to update the Frontal Underrun Protection regulation. “The amendment is proposed in particular to allow more rounded shape of the cab in light of better aerodynamic performance.”   https://www.unece.org/fileadmin/DAM/trans/doc/2018/wp29grsg/GRSG-115-25e.pdf

Good job! Join my Underride Hero Hall of Fame. Certainly ongoing traffic safety research & development is appropriate if the pursuit of the best possible protection for road users is our goal.

Well, then. . . let’s get on with it, shall we?
