The Significance of March 19, 1969, & Truck Underride

Of special interest to those concerned about truck underride is information which I discovered on March 2, 2016. It refers to a published statement by a U.S. DOT agency on March 19, 1969.

That information stuck in my mind more than it would for most people because March 19 is my anniversary and today I celebrated 42 years of marriage to my loving husband, Jerry. Only at the time, I was 13 — not even driving yet.

On that day, 50 years ago, the DOT said that they intended to extend underride protection to the sides of large vehicles. Why would they do that? Because underride is a potential risk all around the truck (except at the tires). They had mandated a weak (we found out thanks to IIHS) rear underride guard but not side.

Imagine. They still have not done so! Many years have come and gone. I have raised a family of nine and buried two of them due to truck underride. And, yet, this country has dragged its feet and neglected to make it a priority to solve the underride problem — despite the fact that technology has advanced by leaps and bounds in other areas.

From that March 2, 2016 post: A Public Comment on Underride Rulemaking re: original intent of NHTSA in 1969

I just read an interesting Public Comment on the Underride Rulemaking: Comment from 7-E Seven Hills Engineering, LLC – Transport Canada

Perry Ponder also commented on the Single Unit Truck Underride Rulemaking last fall: Comment from 7-E Seven Hills Engineering, LLC – Transport Canada

Of special interest to me was the information in both of his Comments on 1969 rulemaking:

“I will begin by pointing out that continuing to allow truck and trailer induced PCI to occur at otherwise survivable crash speeds (delta-V’s of 45mph and beyond) discards years of crashworthiness efforts and wastes the safety benefits we have come to expect and pay for in our cars.

From an engineering perspective the need for vehicle crash compatibility in the form of adequate heavy truck underride guarding is apparent in order to protect against the hazard of PCI which exposes the vulnerable head and neck region to severe, potentially fatal or crippling injury.

This hazard – easily remedied by readily available materials and simple structural analysis – is present also on the sides of heavy trailers and trucks. The FMVSS standard should be broadened to include guarding for the sides and rear of heavy straight trucks, as well as the sides of heavy trailers. This was the original intent of NHTSA rulemakers in the 1969 NPRM, Docket No. 1-11; Notice 2.

Note: Perry Ponder later that year came to the First Underride Roundtable and through connections made there completed development of his AngelWing side guard — successfully tested on March 30, 2017 at the Insurance Institute for Highway Safety:   https://www.youtube.com/watch?v=mrL7AUMT4To

The AngelWing, along with the Safety Skirt, will be tested at the D.C. Underride Crash Test Event on March 26 — as well as a crash into the side of a trailer with no side underride protection.

Other March underride posts:

March has indeed been an eventful month for truck underride. And next week at this time, we will have hosted the first ever D.C. Underride Crash Test Event. 

 

Industry opposition to life-saving measures deepens my grief. Peace in my soul & pain in my heart.

There is peace like a river in my soul but pain does not leave my heart. The ongoing inaction and opposition of the trucking industry, to solutions which could prevent such grief for others, does not make it any easier. In fact, the frustration and anger it stirs up is one more grief too hard to bear.

The power of misinformation and subtle suggestions have the power to sway and delay decisive action. This has gone on far too long. May truth and mercy prevail.

To still my soul in the midst of this raging battle, I am reminding myself of the joy and love of life shared by my daughters during their short time here on this earth before their lives were so abruptly ended by a preventable truck underride crash.

Mary loved to capture every moment on her camera–from the mundane to the amazing. That included our walk on the trails of Battle Park on a beautiful day in January 2013 in her new home of Rocky Mount, North Carolina. Mary’s photo story of the walk with her sister, AnnaLeah, dad, and mom is set to Horatio Spafford’s well-known hymn, “It Is Well With My Soul.” Fitting in so many ways. Peace like a river attendeth my soul.

A Mom’s Response to the OOIDA Letter of Opposition to the Life-preserving #STOPUnderrides! Bill

The STOP Underrides! Bill was re-introduced into Congress on March 5, 2019. On March 7, the Owner Operator Independent Drivers Association wrote a letter of opposition and sent it to the bill’s sponsors.

The following is a combination of the OOIDA letter (bolded) and my response.

Response to the OOIDA Letter of Opposition

(dated March 7, 2019)

To the STOP Underrides Bill

Dear Senator Gillibrand and Senator Rubio,

The purpose of this letter is to convey the Owner-Operator Independent Drivers Association’s (OOIDA) strong opposition to S. 665, the Stop Underrides Act, which would mandate the installation of rear, side and front underride guards on all commercial motor vehicles (CMV) and trailers that exceed 10,000 pounds in gross vehicle weight (GVW).

OOIDA is the largest trade association representing the views and interests of small-business truckers and professional drivers. We have more than 160,000 members nationwide, all of which would be directly impacted by S. 665.

This raises an interesting question. I have personally asked the management of OOIDA to provide me with information about how many owner-operators own their own trailer. He said that he did not have those numbers. Although numbers (1.2 trailer/owner-operator) are listed online, I have seen no documentation that this is the case. I’d love to have proof of this claim but, until then, it does not seem valid to make a blanket statement that all of the OOIDA members would be directly impacted without spelling out what that means.

Over the last several decades, the National Highway Traffic Safety Administration has considered numerous options involving underride guards, but has consistently concluded federal mandates would be impractical and costly, thus outweighing any perceived safety benefits. The reintroduction of the Stop Underrides Act intentionally disregards this reality and ignores the safety, economic, and operational concerns we raised with you last Congress.

Many Public Comments were submitted to the Federal Register, in response to NHTSA proposed underride rulemaking, which raised questions about the validity of the NHTSA cost/benefit analysis. Additionally, Senator Gillibrand responded to all of the concerns, which OOIDA raised in their January 2018 letter, in a letter which she sent to OOIDA on March 16, 2018. Read her reply here.

To be clear, OOIDA supports efforts to improve highway safety. In fact, we agree the existing rear underride guard on trailers – commonly referred to as a “DOT Bumper” in the United States – could be enhanced to reduce the risk of rear underrides for personal automobiles. If the Canadian standard was applied in the U.S. on the manufacture of new trailers, we would not oppose it.

Actually, many of the trailers on the road today in the U.S. already meet the Canadian standard because U.S. transport companies which cross the border need to comply with it. So the U.S. trailer manufacturers responded to that situation. However, those are the same guards which have been tested by the IIHS and found to be ineffective and too weak to withstand offset crashes — even at 35 mph. So simply upgrading the U.S. standard to meet the Canadian standard would not solve the problem — underride, with deadly Passenger Compartment Intrusion (PCI), would still be occurring.

The eight major trailer manufacturers have exceeded the Canadian standard by stepping up to meet the new de facto standard of the IIHS ToughGuard award. It is that standard which we are requesting be mandated by the STOP Underrides legislation to ensure that it is installed on every new trailer manufactured. As of this date, some manufacturers are still selling the older, ineffective rear guard as Standard with the improved guard being offered as Optional.

In addition, there are millions of existing trailers on the road today which still will allow deadly passenger compartment intrusion upon collision. Yet, there are Retrofit Kits available for $500 (or less) which can be installed to upgrade the safety level of rear guards — compared to the $125 it would cost to replace rusted, cracked or bent horizontal tubes at the existing level of ineffective protection.

Unfortunately, S. 665 goes too far. Regarding rear underride guards, it would mandate truckers install them on trailers that can’t physically accommodate them, such as low boys, household goods trailers, auto transporters, etc. The mandate would retroactively apply to all trailers, including those nearing the end of their service.

This comment ignores a basic fact about federal standards. If a CMV is designed in a way that underride is not possible (i.e., there is no geometric mismatch because the truck body is low enough to engage with the passenger vehicle bumper), then, of course, the manufacturer or owner can apply for an exemption. Why would we demand installation of unnecessary equipment?

665 would also mandate the installation of side underride guards. While existing technologies may reduce passenger compartment intrusion in certain situations, the bill fails to recognize numerous other issues limiting the real world practicality of side underride guards. For example, installation of the equipment would unquestionably create challenges for truckers navigating grade crossings and high curbs, backing in to sloped loading docks, properly utilizing spread-axle trailer configurations, conducting DOT-required trailer inspections, and accessing vital equipment located under the trailer – such as brakes. We also want to reiterate S. 665 would mandate side underride guards on trailers that can’t physically accommodate them, such as intermodal, bulk, specialized, and flatbed trailers.

This comment uses an interesting choice of words, e.g., claiming that side guards would “unquestionably” create challenges for truckers. As far as I can tell, these statements are all based on speculation rather than proven fact or documentation. As far as ground clearance (a complaint heard over and over), please see this University of West Virginia study: Development of Design Vehicles for Hang-Up Problem

Here is a quote from the inventor of the AngelWing side guard, Perry Ponder:

AngelWing has undergone extensive standard industry testing and analysis including durability track testing. Designed by a trailer engineer (me), AngelWing works in harmony with existing trailer designs with no effect on the trailer structure or durability.

Here is a video of a trailer with Aaron Kiefer’s SafetySkirt side guard backing over a raised median without any problem:

Further, because the bill applies the underride guard mandate to all CMVs in excess of 10,000 pounds GVW, it would require dually trucks pulling wedge trailers – commonly referred to as “hot shots” – to install these devices. Yet, the exact same dually not operating commercially wouldn’t be required to have them. Here again, most wedge trailers can’t physically accommodate what this bill would mandate.

As stated previously, this comment ignores a basic fact about federal standards. If a CMV is designed in a way that underride is not possible (i.e., there is no geometric mismatch because the truck body is low enough to engage with the passenger vehicle bumper), then, of course, the manufacturer or owner can apply for an exemption. Why would we demand installation of unnecessary equipment? If it is a matter of a unique truck design, which would allow underride if there were no added protection but presents installation challenges, then I would call upon the engineering community to create collaborative solutions. In fact, the bill encourages such communication through the establishment of a Committee On Underride Protection.

665 also mandates a front underride guard on CMVs. Admittedly, we’re less familiar with these devices, because they aren’t currently commercially available in the U.S. However, similar to the rear and side underride guard provisions, this requirement would likely be extremely problematic for reasons we can discuss in more detail at a later time.

I am confident that, if OOIDA genuinely delved into the front underride/override problem — as I did — they would find that there are practical solutions available to change the outcome of crashes which involve trucks rear-ending passenger vehicles or head-on collisions. In fact, U.S. truck manufacturers have patents for front underride protection devices and some are already selling them in countries which have a FUP mandate — including Europe, India, Japan, and Australia.

We would also point out that the bill would require the creation of performance standards for underride devices. Meaning, if an underride guard fails to meet the standard while in operation, the vehicle would be placed out of service and unable to operate. We have no idea how a trucker would get a side underride guard, weighing approximately 1,000 pounds, delivered to the roadside.

Admittedly, it is a challenge to get trucks safely off the road to a repair facility when they have underride protection in a condition which makes them unsafe to travel around. The Commercial Vehicle Safety Alliance ( CVSA ) has addressed this concern in their consultation with the bill sponsors regarding the bill language. But do we just ignore the problem when it is challenging? Do we simply allow the truck driver to continue on with business as usual? Besides, ideally, the truck driver/transport company will do regular pre-trip inspections of the underride protection and address the problem with preventive maintenance or appropriate repair BEFORE the truck ever gets on the road.

Furthermore, OOIDA does not appear to have done their research regarding the weight of side guards currently available. The AngelWing upon early production was weighing in at 800 pounds and has, since then, been reduced to about 500 pounds. Likewise, the Wabash Trailers side guard prototype was reported to weigh approximately 500 pounds.

Nor do we have any idea how the equipment would be installed on the roadside. In sum, the bill mandates devices that aren’t practical, that don’t physically work, and that would create operational impossibilities. We should also note that the bill impacts millions of CMVs, trailers, straight trucks, and other vehicles. With an estimated price tag of tens of billions of dollars, S. 665 would implement the single most costly federal trucking mandate in history.

It seems irresponsible to make a claim about an estimated price tag of tens of billions of dollars. DOT is reportedly a data-driven agency. Please provide specifics as to the equation for reaching conclusions about a safety countermeasure which could save countless lives. In fact, the previous cost/benefit analysis reported by NHTSA actually uses underride data which is well-known to be undercounted. As is also a widely-accepted fact, once the safety equipment is mandated, solutions and manufacturers are likely to rise up to meet the need. Costs will likely go down from their current amounts with competition in the marketplace and improvement of designs/products.

Let’s do some of our own back of the envelope math. Just for the sake of discussion, let’s say that a tractor-trailer owner put $3,400 into underride protection equipment — and that’s for a retrofit. Divide that $3,400 into 15 years average trailer life and you have $227/year or $0.62/week. Don’t forget IRS Section 179 allows a tax deduction for business equipment.

And on what information does OOIDA base their claim that “S. 665 would implement the single most costly federal trucking mandate in history”? From what I read, the Electronic Logging Device (ELD) mandate cost truck owners on average $495/truck/year. And read what that website says about the rumors spread about prohibitive costs of ELDs which would put trucking companies out of business (sound familiar?): Considering the overall operational costs of a trucking business, ELD investment doesn’t rank when compared to operating expenses, like fuel, liability insurance, tractor-trailer equipment, and permitting costs.

Is it truly inappropriate to think that safety equipment, like underride protective devices, should be considered a normal, acceptable Cost Of Doing Business (CODB)?

While we’re at it, please answer a question which I have had for several years now. . . even if you estimate the industry’s safety budget at $9.6 billion, as Chris Spear did in a conversation with me in March 2017, please tell me what percentage that is of the total operating budget — or revenue or profit or whatever figure you want to use — for the trucking industry.

Well, if they don’t want to tell me, I’ll have to estimate it myself. This article quotes ATA as saying that in 2017 the trucking industry revenue was $700.3 billion. That would mean that the safety budget (which included drug tests for drivers) was 1.4%. What is included in that?

These investments include technologies on the truck such as collision avoidance systems, electronic logging devices for driver hours of service compliance and video event recorders. They also include driver safety training, driver safety incentive pay, and compliance with safety regulations (e.g., pre-employment and random drug tests and motor vehicle record checks). The largest investment category is in driver safety training, equaling 36% of all investment. Driver safety training was followed by expenditures in compliance with safety rules (26%), on-board safety technologies (25%) and driver safety incentive pay (13%). https://www.trucking.org/ATA%20Docs/News%20and%20Information/Reports%20Trends%20and%20Statistics/06%2028%2016%20-%20Trucking%20Industry%20Invests%20%249%205%20Billion%20in%20Safety%20Annually.pdf

OOIDA hasn’t shared with us their back of the envelope math equation. But here is mine:

Let’s say that there are approximately 2 million existing trailers and 300,000 new trailers/year. Make that 2,500,000 or even 3,000,000 x $3,000/tractor-trailer = $9,000,000,000 or $9 billion. That would be 1.3% of the revenue amount. Is that an unreasonable cost of doing business?

If 1000 lives were saved (plus untold catastrophic, debilitating injuries prevented), that would be $9,000,000/life saved. The DOT sets the Value of a Saved Life (VSL) at $9.6 million.

Obviously, that amount includes retrofitting existing trailers which would not have to be repeated every year. But, even with this rough math calculations, I’m having a hard time seeing what is causing a panic.

Furthermore, is OOIDA helping their membership to look at the broad picture of how comprehensive underride protection can actually benefit the trucking industry? That includes the greatly decreased insurance risk when truck crashes lead to fewer fatalities.

We would encourage you to learn more about the trucking industry, including its incredible diversity, before continuing to promote S. 665. One-size-fits-all solutions simply don’t work.

I would encourage OOIDA, and others in the trucking industry, to thoroughly do their due diligence on the underride problem and solutions. Take it on as collaborative challenge to reach a mutually-beneficial goal: safer trucking. Take advantage of the upcoming opportunity to witness an underride crash and two successful side underride protective devices firsthand at the D.C. Underride Crash Test on March 26.

As a bonus, here are my responses to concerns expressed by the American Trucking Associations (ATA) about the STOP Underrides! Bill:

Question for the ATA: Is it necessary to choose EITHER crash avoidance OR occupant protection — not BOTH?

My knee-jerk reaction to the ATA Letter of Opposition to the STOP Underrides! Bill

Back-of-the-Envelope Math for Underride Protection Retrofit Cost/Trailer Equation

Back-of-the-Envelope Math for Underride Protection Retrofit Cost/Trailer Equation

Let’s do some simple back-of-the-envelope math. How much would it cost to retrofit a trailer? The current estimated cost would be:

Rear guard $ 500

AngelWing Side guard $2,900

Equipment total $3,400

(TrailerGuard SafetySkirt side/rear underride protection system estimate $2,500)

Estimated years of service for a trailer = 15 years

$3,400/15 years = $227/yr

$227 yr./365 days = $0.62/day

So, for $0.62 per day, the trailer owner has the following benefits:

  1. An underride crash with fatalities or life-altering injuries can take a settlement beyond insurance policy limits. Current minimum liability is $750,000; many carriers carry $1 million — large carriers may carry more.
  2. Underride crashes can lead to bankruptcy for independent owner operators and small motor carriers.
  3. Those opposing the bill are not doing a favor to truck drivers, owner operators, and small carriers.
  4. Truck drivers, in general, don’t understand that underride protection will benefit them. It will save their livelihoods.
  5. It will keep truck drivers, who are at fault in a crash, from going to jail if an underride death can be prevented.
  6. It will decrease liability costs, which should decrease their insurance costs.
  7. It could prevent PTSD from being involved in a fatal truck crash (no matter what caused the crash).
  8. A “closed casket crash” impacts truck drivers for a lifetime.
  9. If truck owners would break down the costs of adding the protection over the life of a trailer (10-15 years), it comes out to a very small amount/month — approx. $ .62/day.
  10. Tax deduction from IRS Section 179 for safety equipment purchase.
  11. When side guards are combined with side skirts, it can provide additional fuel savings.
  12. By the way: Allowing underride crashes wastes all of the safety R&D which the auto industry has put into improving the safety features of cars (crush/crumple zone, airbags, seatbelts).

Senators Gillibrand & Rubio and Representatives Cohen & DeSaulnier Reintroduce Bipartisan Underride Bill

March has been a momentous month for truck underride. Continuing along that line, the STOP Underrides! Bill has been re-introduced to Congress by its sponsors, Senators Gillibrand and Rubio and Representatives Cohen and DeSaulnier, on March 5.

See Senator Gillibrand’s Press Release here and Senator Rubio’s here.

To convince Congress of the importance of this bill to end Death By Underride, we will be hosting an Underride Crash Test Event in Washington, D.C., starting at 10:00 a.m. on March 26 (watch for livestreaming from Eric Flack & WUSA 9).

Consumer Reports urges Congress to pass the Stop Underrides Act

The STOP Underrides! Bill is now S.665 (referred to the Senate Commerce, Science, & Transportation Committee) and HR.1511 (referred to the House Transportation & Infrastructure Committee).

@NTSB & @NHTSAgov didn’t call for side guards after 2016 Tesla underride fatality; will they after a 2nd?

NHTSA investigated the May 2016 side underride crash of Joshua Brown’s Tesla. Here is the report which they published in January 2018.

Special Crash Investigations:
On-Site Automated Driver Assistance
System Crash Investigation of the
2015 Tesla Model S 70D 812481

Read this description of the injuries which the driver suffered as a result of Passenger Compartment Intrusion (PCI) from truck underride:

The front plane of the Tesla underrode the mid-aspect of the semi-trailer in the intersection, and the first crash event occurred as the base of the windshield and both A-pillars of the Tesla impacted and engaged the sill/frame of the semi-trailer’s right plane/undercarriage. Directions of force were in the 12 o’clock sector for the Tesla and the 3 o’clock sector for the UTI semitrailer. The Tesla maintained its momentum and completely underrode the semi-trailer, which sheared the entire greenhouse and roof structure from the Tesla.

During the underride impact, the driver’s face and head contacted multiple intruding components. These contacts produced fatal injuries to the driver. Intruding components and the semi-trailer also contacted and deformed both front row seatbacks and all of the Tesla’s structural pillars. The sheared roof and tailgate/hatch of the Tesla were captured by the right plane of the semi-trailer as the vehicle continued beneath it, and became deposited in the roadway at the location of the impact.

Please explain to me why NHTSA did not suggest that side guards might have changed the outcome of the crash and, furthermore, took no action to initiate rulemaking to mandate side underride protection.

NTSB also investigated the May 2016 Tesla crash and made no side guard recommendations.

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

Congress, Act Now To End Deadly Truck Underride!

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

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:

STOP Underrides! Petition

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?

“AEB that reliably detects trucks could prevent underride crashes.” Meanwhile, what should we do?

Automatic emergency braking (AEB) on passenger vehicles is a good thing. It’s purpose is to reduce the chance of a rear-end collision or decrease the severity of the impact if it does occur. But does it function as intended when the vehicle in front of a car is a large truck?

A recent report from the Insurance Institute for Highway Safety (IIHS) implies that it does not reliably do so:

When it comes to preventing typical front-to-rear crashes, automatic emergency braking is a proven winner. Extending its functionality to address less-common types of rear-end crashes involving turning, changing lanes or striking heavy trucks or motorcycles, for instance, would help maximize autobrake’s benefits, a new IIHS study indicates. . .

Autobrake systems that reliably detect large trucks could prevent underride crashes. Twelve percent of U.S. passenger vehicle occupant deaths in 2017 were in crashes with large trucks, and 1 in 5 of these deaths occurred when a passenger vehicle struck the rear of a large truck.

Autobrake is good, but it could be better, IIHS, Status Report, Vol. 54, No. 2, February 21, 2019

If I am interpreting this correctly, this means that, currently, AEB on many vehicles do not reliably detect large trucks in order to prevent underride crashes. This is no surprise as there is almost 4 feet from the bottom of most trucks to the ground; the sensors are apparently not located in such a way as to be able to detect the truck body. No threat is recognized.

Therefore, it appears to me that we cannot rely on the current collision avoidance technology to prevent rear-end collisions of cars into trucks. If we want to more reliably prevent deadly underride and gruesome passenger compartment intrusion, why then would we not install effective comprehensive underride protection on all large trucks?

See what happens when collision does occur into the rear of a truck which is and is not equipped with an effective rear underride guard:

By the way, the same is, of course, true for the sides of large trucks where there is nothing but open space — nothing for the car’s sensors to detect. What will we do about that?

AngelWing Crash Test at IIHS, March 30, 2017

Trucker Slow-Roll Protest Raises Awareness of Controversy Over How to End Truck Driver Fatigue Tragedies

There is ongoing and complicated controversy over how to prevent Truck Driver Fatigue. It involves how they are kept accountable for their time on the road (the paper logbook was converted to Electronic Log Books in December 2017), as well as the details of Hours Of Service (HOS) requirements. But the bottomline is how truck drivers get compensated.
Some truck drivers have taken the matter into their own hands to raise awareness of the problem and staged a “Slow-Roll Protest” in Indiana on February 21, 2019. Read about it here: Truckers ‘slow roll’ in Indiana protest
 
This is why I hope to realize my goal of organizing a Tired Trucker Roundtable — to catalyze collaborative conversation and action in order to end the ongoing tug-of-war over these regulations (or lack thereof).
