Unguarded: Death By Underride

Safety Advocacy, Truck Safety, , ,

Looking for an explanation of the truck underride problem and solutions? Look no further. Eric Hein, the father of side underride victim Riley Hein, has put together a detailed tool for learning more about underride and what can be done about it:

Unguarded: Death By Underride

Here are a few excerpts:

People die every day from side underride crashes

An “underride” is a collision between an automobile and a truck or semitrailer, and due to the height differential between the passenger vehicle and the frame of the semitrailer, the vehicle goes partially or completely under the side of the semitrailer. During a collision (see unguarded and guarded crash test here), the passenger vehicle impacts the side of the semitrailer with parts of the vehicle not designed to absorb crash forces, namely the windshield and those areas above the hood. This type of collision causes deaths and severe injuries – death by decapitation, crushing, or explosion commonly result. These catastrophic collisions would otherwise be survivable, but side underride guards on trucks and semitrailers are lacking.

Sadly, the recognized hazard of side underride collisions with towed trailers can be traced back to at least 1935 when Robinson patented an invention for a peripheral guard on a hitch-mounted trailer.

Industry Opposition Claims Are False

The technology is feasible and available. The trucking industry has lobbied against underride guards since 1971 and continues to inaccurately claim that side underride guards are infeasible. Contrary to industry, side underride guards ARE available – they are widely used in Europe, and have been tested and installed in the USA such as the AngelWing and Fortier in Canada.

Underride Guards Are Aerodynamic and Save Fuel Cost. Wabash engineered a combination side impact guard and skirt that passed tests for a 90-degree centerline vehicle impact at 35 miles per hour, and uses a braided cable and is 40 to 50 percent lighter than other designs. With an aerodynamic skirt installed on the underride guard, about 704 gallons ($2,153 using $3.06/gallon) of diesel fuel would be saved annually (8,448 gallons or $25,836 over the 12-year life of a semitrailer) and would completely offset the guard’s cost.

Underride Guards Safeguard Truck Drivers. Side guards on semitrailers change the outcome of collisions to fender benders and reduce the risk of death for people in passenger vehicles, which shield truck drivers from the prospect of jail time or losing their jobs.

All this talk of side skirts for fuel savings & not one word about side guards for life saving!

Safety Advocacy, Truck Safety, , , , ,

A recent article from Transport Topics caught my eye. It’s all about this & that concerning side skirts on trailers (for fuel savings). Lots for a trailer buyer to consider when making a decision.

Installing the complete system takes 2.5 man-hours, he said.

Wikipedia has to say this about cost: As of 2009, a set of trailer skirts cost between C$1500 and C$3000 (US$1300 to $2700). Standard trailer skirts have an estimated payback period of ten to eighteen months, while “advanced” skirts (those that improve fuel efficiency by over 7%) are estimated to pay for themselves in seven to fourteen months.

Seriously?! An AngelWing side guard can be installed in close to that amount of time. And if side guards were socially acceptable and widely embraced so that they readily available to purchase (you know how supply and demand works, right?), the price could quite likely be comparable. Plus side guards may enhance fuel savings when used with side skirts.

So why the fuss from the industry about the cost of LIFE-SAVING side guards!?

Read the whole article for yourself and tell me why there is such resistance to installing comprehensive and effective underride protection and outright opposition toward a mandate which would require it.

Super Single Tires Could Offset Cost of Side Guards: Save Weight/Cost/Lives!

Safety Advocacy, Truck Safety, , , , , ,

Super single tires (in place of the more common dual tire set-up) on semi-trailers could actually save weight, cost, and — when combined with side guards — lives! Sounds like a Win/Win scenario to me! But don’t take my word for it, read about the potential benefits in this truck driver blogpost:

Essentially, instead of having eighteen tires to support the trailer and truck, only ten will be needed because of the improved design of the tire itself. The super single truck tires can withstand the weight of the trailer and vehicle over the same time period as their dual counterparts. A study performed by the Oak Ridge National Laboratory showed that trucks could save an average of almost 3% on gas or diesel fuel. While 3% may not sound like much, over 125,000 miles and averaging five miles per gallon that results in a savings of 728 gallons per year.

In addition, the new tires actually offer more stability with a wider truck frame. However, the most interesting advantages are that these tires can hold up for about 200,000 miles as opposed to the standard 160,000 miles for the conventional tires. This means that money is saved on replacement as well since the fewer number of super singles which actually last 40,000 miles longer.

However, the main advantage that super singles offer is that they are stronger, yet lighter in weight than their standard counterparts by roughly 1,000 pounds in total. While this weight savings may translate to better fuel mileage, trucking companies see this as being able to add 1,000 more pounds to the cargo. This means that more can be hauled on a single trip which can earn the company even more money than before.

Possible Drawback (as mentioned in the video below) is what could happen when there is a tire blow-out.

Prior to Our Crash on May 4, 2013, our family had become good friends with another family. Their youngest, a pre-schooler at the time, followed Mary (13) around and was sure that he was going to marry her. Last week, his mom shared this with me:
 
Marianne, a couple of days ago I took [her son, now 8] to WalMart. On the way out of the parking lot, he started YELLING, “Mom! Mom! Mrs. Karth got the law passed, Mrs. Karth got the law passed!!!”
 
Huh? What on earth was that boy talking about??? I turned around and there was a semi with the guards on the side! I had no idea he knew anything about what we’ve been talking about all these years! 🙂
 
I wish it were true. . . 
 
Bless his heart!!!!!! 🙂   What he likely saw was a side skirt for fuel savings ($).
 
I look forward to that day when we can all drive down the road and rejoice at the safer trucks because, finally, saving lives will have become more important than saving $! I will sing & dance & thank the Lord for all that He has done.
I’m sure that Mary & AnnaLeah — were they here — would join me!

Truck Underride 101: Part IV Win/Win

Truck Safety, , , , ,

Becoming educated about underride was not a direction I had planned on going with my life and time. But I have gained a great deal of knowledge related to the fact that AnnaLeah’s and Mary’s deaths (and Roya’s, too, along with countless other individual loved ones) might have been prevented had adequate underride protection been on the truck, into which our sturdy Crown Vic crashed — along with the fact that many more countless, unknown individuals will die unless this country takes decisive action.

This information, along with my unresolved grief due to the frustration of knowing that years have gone by without effective protection, fuels my efforts to work collaboratively to bring about widespread and significant change. It is now my aim to equip everyone with the same information — without the accompanying unwanted grief.

When you think about it, this should really be a win/win situation. Here is Truck Underride 101: Part IV Win/Win.

IV. Win/Win

  1. Job Creation Quite simply put, a mandate for comprehensive underride protection (which some members of the manufacturing industry have said would take the burden off of them to persuade their customers to install these safety features) would lead to a demand for equipment which would, in effect, create new jobs.

  2. Fuel Savings/Super Truck Project: 

  3. Underride Protection: RETROFIT 

  4. Second Collision: Crash Avoidance/Underride Protection: What is a “Second Collision”? Read about it here: Second Collision and Underride Protection

  5. BOTH/AND and opposing arguments: This post contains numerous links dealing with the issue of crash avoidance vs underride protection: Preventing deadly crashes doesn’t require Either crash avoidance Or underride guards but Both/And.

Editor’s Picks from Trucks.com include these recent articles:

 

  • All these programs are funded locally and don’t rely on federal dollars. Nagrani said federal green truck grants, for example, will amount to just one tenth the level of what California offers and are split among all 50 states.He expects continued interest.

    “Everybody wants clean air regardless of what the Trump administration has said,” Nagrani said.  Alternative Fuel Trucks Abound at Industry Show, But Buyers Sparse, JERRY HIRSCH MARCH 17, 2017 EDITOR’S PICKS, TRUCKING TECHNOLOGY, Trucks.com

Will truckers be provided with working conditions which foster their own personal well-being as well as safe driving behavior?

Side guards on trucks could provide fuel savings and save lives by preventing deadly side underride.

Does everybody want safer trucking? Do we?

DOE pours millions into SuperTruck fuel savings research projects; $0 devoted to side underride protection?

Safety Advocacy, Truck Safety, , , ,

How is it that the DOE and Volvo poured resources into research and development of SuperTrucks but did not bother to (as far as I can tell, though I am not done looking into this yet) include improved underride protection as a goal of this project?!

  4. Aerodynamic improvements that reduce the trailer’s drag coefficient by more than 30%. The vehicle is part of the DOE’s SuperTruck program – a five-year research and development initiative aimed at improving freight efficiency, based in the measure of the payload carried while burning less fuel.

Its objective is to develop and demonstrate a 50% improvement in overall freight efficiency on a Class 8 tractor-trailer vehicle as measured in ton-miles per gallon of diesel fuel.

Could they not have combined resources with DOT to accomplish such a thing?

Again, cost-savings over life-savings.

Can we use the potential fuel efficiency cost-savings of side guards advantageously to win the cost/benefit analysis battle?

Super Truck II is announced! Let’s get DOT to be involved with this project! $20,000 fuel savings/year could go to safety research!!!!!!!!!!!!

U.S. Energy Secretary Ernest Moniz was present for the unveiling of Volvo’s SuperTruck concept/demo rig in Washington, D.C. Here’s what he had to say about reaching the DOE’s next step in the fuel economy/freight efficiency project: SuperTruck II. http://www.truckinginfo. com/video/detail/2016/09/on- the-spot-reaching-for- supertruck-ii-video.aspx

More information on this SuperTruck project and random frustrated reactions:

$20 million in federal funding for the Super Truck II project and we can’t get diddly for side guard research?!?!?!!?!

http://www.truckinginfo.com/channel/fuel-smarts/news/story/2016/08/volvo-group-outlines-supertruck-ii-plans.aspx  Volvo Group has outlined how it plans to use $20 million in federal funding to further the freight-moving efficiency of heavy-duty trucks as part of the SuperTruck II initiative.

Volvo Group said its team of researchers and engineers will use alternative engine designs and an integrated system approach to build a lightweight tractor-trailer concept that will exceed the freight efficiency goal of 100% improvement on a ton-mile-per-gallon basis compared to a 2009 baseline. The team is also tasked with demonstrating powertrain capable of 55% brake thermal efficiency. Volvo Group and its partners will match the development funds dollar-for-dollar.

To achieve these goals, the company plans to leverage its experience in vehicle development along with established partnerships with advanced technology and trailer equipment vendors.

Those partners include Michelin Americas Research Company for tires, Wabash National for trailers, Metalso for lightweight frames, Johnson-Matthey for exhaust aftertreatment systems, and Peloton Technology for platooning and connected vehicle tech. . .

Daimler Trucks North America will develop and demonstrate a tractor-trailer combination using a suite of technologies including active aerodynamics, cylinder deactivation, hybridization, and the electrification of accessories. . .

Yet more disturbing information:

This gives links to multiple articles on the SuperTruck project: http://www.truckinginfo.com/list/tag/supertruck.aspx

Trailer aerodynamics have become increasingly important in recent years as truck operators see that they can save fuel money. They’re so important that the federal government is paying several teams of truck and trailer makers to design concept rigs that show what’s possible in this area of science.

As far back as the 1980s I’ve written about various types of trailer aero fairings, from Nose Cones to TrailerTails and many brands of skirts and other appendages in between.

Here’s one I don’t recall writing about, at least not lately: the UnderTray and other products from SmartTruck. The company has posted a YouTube video depicting a tractor-trailer moving through the air at highway speed, with streamlines showing how the devices smooth air flow over the vehicle. Check it out here. 

Also note the Diffuser, SmartTruck’s device mounted ahead of the rear underride guard that redirects air away from its vertical and horizontal members. These otherwise grab at the air and create drag. (Old timers still call this the “ICC bumper” because the old Interstate Commerce Commission required them, something I definitely don’t recall being a fact, but it’s part of trucking vocabulary.)

The trailer portion of Freightliner’s SuperTruck of course got large panels that improve air flow around corners, deep skirts to keep air away from the Strick van’s undercarriage and tandem, and a boat tail similar to a Trailer Tail, but home-made. One would expect all of those.

What?!?!?!?!?!?! All of this government money going into research & development for fuel savings but not a word or project related to underride protection/SAFETY?!
