I have seen quite a few underride guard crash tests in the last two years. It’s not something I ever planned to do and it is never easy. Some of them ended in severe underride and it always shakes me up at how quickly life can change forever. In a matter of seconds.
The crash test I viewed at IIHS on January 19, 2017, was particularly hard to watch. It was a test of Great Dane’s newly designed rear underride guard. A Great Dane trailer was what our Crown Vic collided with on May 4, 2013 — with tragic results.
Demonstration of Improvement in Rear Underride Guard; Great Dane Trailers Crash Test at IIHS, January 19, 2017:
They have proven that creative minds can come up with better underride protection. The cars are damaged from the crash, but underride and Passenger Compartment Intrusion (PCI) are prevented. Lives are preserved.
Here is a Youtube video, posted by Cars-Trucks TV, which demonstrates the effectiveness of the improved rear underride guards designed by five of the major trailer manufacturers — Great Dane, Manac, Stoughton, Vanguard, and Wabash — from 2013 to 2017. They received a Toughguard award from IIHS — as announced on March 1, 2017.
Here is an excerpt: It is my fervent hope that, when March 2017 rolls around, we will be celebrating a vastly improved federal standard–enthusiastically and immediately adopted by the trucking industry–for all-around-the-truck underride protection at higher speeds, including now-exempt single unit trucks as well as retrofitted to existing trucks and trailers.
If this seems like a costly venture, try comparing it to the price paid by thousands upon thousands of individuals and families during the past decades of ineffective underride protection–added to the countless precious people who will be saved in the years to come from tragic, preventable death by underride.
We aren’t finished yet, but we have come a long ways!
On March 1, 2017, IIHS announced a new award, Toughguard, given to trailer manufacturers which have passed the IIHS rear underride guard crash testing:
Five North American semitrailer manufacturers earn the Insurance Institute for Highway Safety’s new TOUGHGUARD award recognizing rear underride guards that are designed to prevent a range of deadly underride crashes. Semitrailers from Great Dane LLC, Manac Inc., Stoughton Trailers LLC, Vanguard National Trailer Corp. and Wabash National Corp. earn the accolade. IIHS recognizes semitrailers with good underride guards
Thank you, IIHS for your commitment to this crash testing project, which has highlighted the continuing underride problem and guided the way to a solution. Thank you, as well, to the trailer manufacturers who have voluntarily improved the rear underride protection on the trailers which they produce and sell (and/or lease).
After two full days of attending the ATA’s Technology & Maintenance Council conference in Nashville, I am having a hard time figuring out what to talk about first.
It has been very good to spend that time with Lois Durso, a mom who also lost a daughter to truck (side) underride. We first began talking on the phone a couple of weeks ago and planned to meet at the conference. Having a bond of similar grief, we have talked almost non-stop — both about our daughters as well as strategies for truck safety.
In fact, we were both guests of Stoughton Trailers at the conference and they asked me to share our family’s crash story and the safety advocacy which followed, as well as our appreciation of how Stoughton stepped up and voluntarily improved their rear impact guard and are able to offer it as standard on all new dry van trailers — at no added cost or weight penalty to their customers.

I received a wonderful surprise this morning when I unexpectedly found out that Stoughton now has a rear impact guard (RIG) retrofit kit available for purchase to install as a replacement on all existing (compatible) Stoughton trailers, as far back as 2007. I talked with the Products manager and she roughly estimated the cost to trailer owners to be around $500-600.
I am not indicating that Stoughton’s new RIG is necessarily better than any of the other manufacturers who have also stepped up to the plate and designed rear guards to receive the Toughguard award. But I am commending them for making the safety of the driving public a priority. In fact, I do not have specific crash test information to rate one new design compared to the others. At the end of the day, Jerry and I are thankful to the many persons and companies which have helped to bring about this progress in underride protection.
We will continue to advocate for the strongest possible underride protection on all trucks. That, of course, includes side underride protection, which Lois and I discussed with many industry leaders this week. It also means that Single Unit Trucks still need to be addressed, along with front override, retrofitting, maintenance, and identifying the outer limits of underride protection.
We are not done yet. They haven’t seen the last of us. We’ve got more lives to save.

Stay tuned for news from IIHS on trailer manufacturer underride protection awards.
Thank you, IIHS for your commitment to this crash testing project, which has highlighted the continuing underride problem and guided the way to a solution. Thank you, as well, to the trailer manufacturers who have voluntarily improved the rear underride protection on the trailers which they produce and sell (and/or lease).
Here is a Youtube video, of IIHS crash testing research, which shows improvement in the rear underride guards of major trailer manufacturers.
They have proven that creative minds can come up with better underride protection. The cars are damaged from the crash, but underride is prevented and lives are preserved.
The challenge mentioned here is for car companies to address the need for occupant protection on the passenger side as well as the driver side in frontal crashes. Duh!
As a mom of nine — although they are now grown — it seems commonsense to me to provide occupant protection throughout the entire vehicle! Including protection for passengers from seatback failures.
I am thankful for the valuable work which the Insurance Institute for Highway Safety does to advance vehicle safety through their crash test ratings. That includes large trucks.
I hope to see a 5-star crash rating system for the underride protection system on large trucks soon. It could mean the difference between life and death for someone.
May 5 Underride Roundtable will explore ways to address deaths and injuries in truck underride crashes
RUCKERSVILLE, Va. — The Insurance Institute for Highway Safety, Truck Safety Coalition and AnnaLeah & Mary for Truck Safety will hold a national meeting on the problem of truck underride crashes on Thursday, May 5. Researchers, government officials and industry leaders will gather to discuss how to reduce the risks for passenger vehicle occupants, bicyclists and pedestrians.
In 2015, 371 of 2,485 passenger vehicle occupants killed in large truck crashes died when the fronts of their vehicles struck the rears of trucks. Pedestrians and bicyclists also died in collisions involving the sides of trucks.
IIHS will conduct a crash test of a trailer with an improved underride guard.
Who: IIHS, Truck Safety Coalition and AnnaLeah & Mary for Truck Safety
What: Truck Underride Roundtable
Where: IIHS Vehicle Research Center, 988 Dairy Road, Ruckersville VA 22968
When: Thursday, May 5, 2016 from 9:00 AM to 4:00 PM
Crash test will be conducted at 12:30 PM.
Media need to be in place by 12:15 PM for the test.
A proposed upgrade to rear underride guard regulations for tractor-trailers is a move in the right direction but isn’t comprehensive enough to deliver the safety gains IIHS outlined in a 2011 petition for rulemaking, especially when it comes to preventing underride in offset crashes. . .
Thank you, IIHS, for your ongoing involvement in underride protection.
IIHS was reporting on a meeting that took place on March 16, 1977 — three days before I got married! That’s almost 39 years ago — long before any of my 9 children were born, let alone my two youngest daughters, AnnaLeah and Mary!
The government and industry apparently didn’t get underride rulemaking right then! And they clearly hadn’t gotten it right by May 4, 2013 — when Mary and AnnaLeah died from truck underride! But they better watch out, because I am not going to sit by and watch while thousands more die for no good reason!
See the testimony in May 2009 by the Insurance Institute for Highway Safety, in which they call for tougher underride guard standards and with an attachment of the history of federal rulemaking on underride guards (pasted below): http://tinyurl.com/phlaqon
“The history of Federal rulemaking on truck underride guards:
1953 Interstate Commerce Commission adopts rule requiring rear underride guards on trucks and trailers but sets no strength requirements.
1967 National Highway Safety Bureau (NHSB), predecessor to the National Highway Traffic Safety Administration (NHTSA), indicates it will develop a standard for truck underride guards.
1969 NHSB indicates it will conduct research on heavy vehicle underride guard configurations to provide data for the preparation of a standard. In the same year the Federal Highway Administration publishes a proposal to require trailers and trucks to have strong rear-end structures extending to within 18 inches of the road surface.
1970 NHSB says it would be “impracticable” for manufacturers to engineer improved underride protectors into new vehicles before 1972. The agency considers an effective date of January 1, 1974 for requiring underride guards with energy-absorbing features as opposed to rigid barriers.
1971 National Transportation Safety Board (NTSB) recommends that NHTSA require energy-absorbing underride and override barriers on trucks, buses, and trailers. Later in the same year NHTSA abandons its underride rulemaking, saying it has “no control over the vehicles after they are sold” and “it can only be assumed that certain operators will remove the underride guard.” The Bureau of Motor Carrier Safety (BMCS), predecessor to the Federal Motor Carrier Safety Administration, considers a regulatory change that would prohibit alteration of manufacturer-installed equipment. This would nullify the major reason NHTSA cited for abandoning the proposed underride standard.
1972 NTSB urges NHTSA to renew the abandoned underride proposal.
1974 US Secretary of Transportation says deaths in cars that underride trucks would have to quadruple before underride protection would be considered cost beneficial.
1977 IIHS testifies before the Consumer Subcommittee of the US Senate Commerce Committee, noting that devices to stop underride have been technologically available for years. IIHS tests demonstrate that a crash at less than 30 mph of a subcompact car into a guard meeting current requirements results in severe underride. IIHS also demonstrates the feasibility of effective underride guards that do not add significant weight to trucks. IIHS petitions NHTSA to initiate rulemaking to establish a rear underride standard. The agency agrees to reassess the need for such a standard and later in the year announces plans to require more effective rear underride protection. BMCS publishes a new but weak proposal regarding underride protection.
1981 NHTSA issues a proposal to require upgraded underride protection.
1986 IIHS study reveals that rear guards designed to prevent cars from underriding trucks appear to be working well on British rigs.
1987 European underride standard is shown to reduce deaths caused by underride crashes.
1996 NHTSA finally issues a new standard, effective 1998.”

“Rear underride crashes kill thousands of people yearly worldwide. Underride guards did not follow the progress achieved by the automotive safety technology. . .”
