NHTSA denies crash victim families’ request for truck rear-guard probe

Issues raised by parents of children killed in crashes can be addressed by ongoing agency actions, according to regulators

WASHINGTON — Federal regulators have declined a request by parents of children killed in truck crashes to open an investigation into defective truck equipment designed to prevent fatalities in collisions with automobiles.

In denying petition filed in 2022 by Jerry and Marianne Karth, Eric Hein, and Lois Durso-Hawkins, the National Highway Traffic Safety Administration ruled that the issues raised “are best addressed through its recent rulemaking and the ongoing actions” undertaken by NHTSA as required by the 2021 Bipartisan Infrastructure Law, according to Eileen Sullivan, NHTSA’s associate administrator for enforcement, in a notice issued Tuesday.

Specifically, the petitioners were seeking an investigation — and subsequent equipment recall — into fatal crashes in which passenger cars collide with the rear end of a truck, referred to as an underride, due to a defective or a missing rear impact guard (RIG) mounted on the back of van-type or box trailers.

“The DOT can no longer feign ignorance to the danger of rear underride collisions,” the petitioners wrote. “NHTSA must conduct an analysis, in which they will certainly find that this known defect poses an unreasonable risk to motor vehicle safety and is therefore a ‘safety defect,’ and subsequently order manufacturers to conduct a recall to mitigate the dangers of death and serious injury from semi-trailers lacking effective rear impact guards.”


They further noted that without a government recall, “truck and trailer manufacturers and owners will not voluntarily stop the known unreasonable risk to public safety by designing and implementing safer trucks and trailers with effective rear underride prevention guards.

“Crash tests demonstrate that more effective rear underride guard technology is available, has been well-studied, and would be an easy and inexpensive solution to the known hazard of rear underride collisions to the traveling public.”

In response, Sullivan stated that after reviewing over 200 news articles reporting on fatal truck crashes that the petitioners submitted in the record, NHTSA found that only 22 involved box trailers. Of those, the agency “was able to identify the trailer manufacturer in nine; however, none of the model years could be determined,” she said.

Sullivan also pointed out that a month after the investigation request was filed, NHTSA finalized new minimum rear-guard safety standards, which replaced original standards released in 1996. The updated standards went into effect Jan. 11, 2023, and have a compliance date of no later than July 15, 2024.


NHTSA’s final rule, however, was derided by safety advocates as not going far enough. Notably, Joan Claybrook, a former NHTSA administrator, called the rule “regulatory malpractice,” in part because 94% of trailers already met the standards. “NHTSA has lowered the bar on public safety instead of ensuring it,” she said at the time.

In addition to the rear-guard rule, Sullivan said NHTSA is conducting research on rear impact guard designs that better protect passenger vehicle occupants in more scenarios involving rear underride crashes.

Since the petition was filed, Karth was appointed to NHTSA’s advisory committee on underride protection, which was created to provide advice and recommendations to the U.S. Department of Transportation on safety regulations to reduce underride crashes.

Contacted for a response to NHTSA’s denial of her petition, Karth, whose daughters AnnaLeah and Mary died as a result of injuries suffered in an underride crash in 2013, said she was frustrated.

“NHTSA references the 2022 final rule, which updated previous standards but still falls short of standards that insurers and manufacturers have shown can prevent underride crashes,” Karth told FreightWaves.

“My hope is that they’ll at least do what they said they’ll do in the decision, which is that this doesn’t prevent the agency from taking further action if warranted. If we can get strong results that justify strengthening the rear rule, I hope that will also justify NHTSA proceeding with this investigation.

    My daughter was killed biking to work by an underride caused by a box truck driver who turned into her path. The comments above are knowingly and shamelessly false, relying on false data from NHTSA. NHTSA has known for decades that there’s a reasonable solution. Google “America’s Dangerous Trucks” to watch a film which explains why NHTSA has done almost nothing to save lives. My daughter is one of the tragic and unnecessary victims of this carnage

    Most van trailers are adequately protected as to box trailers most aren’t. What about pick up trucks raised so much my car can even reach the gas or diesel tank any studies on these? Years ago I built a street rod in Illinois and had to comply with no more than 11inch clearance.

    Another thing, every time the government adds new mandates to truckers, stuff like this, it causes the prices of shipping to increase which starts a domino effect on prices for everything we purchase. But I have to remember we live in a society that blames others for everything, no personal responsibility, give me, give me, give me. My heart does hurt for the loss of someone life, that could have been avoided. My heart aches for truckers who are involved in accidents, they are scarred for life and most of the time it was not even their fault. They too have to live with knowing someone was killed while he was driving.

    Some crashes sincerely are not the fault of the car that was pushed under the RIG, it is caused by someone rear-ending them. But then you have to question why was that car so close to the truck that it could be pushed under anyway and or why were they so close that when the truck stopped they did not have time to react. We blame truckers for too many accidents and working in the freight industry I have seen footage from trucks that have rear, side, front and inside the cab cameras, a major expense for the truckers, but one they are willing to make because this footage may be all that saves their careers and this employer from being sued. Passenger cars cannot compete with anything larger than it, so why not slow down and allow room for the vehicles in front of you. At some point everyone has to take responsibility for their actions – better late than never! SLOW DOWN, GIVE THE SPACE NEEDED BETWEEN YOU AND ANY VEHICLE even at stop lights, remember if you cannot see the vehicles mirrors they cannot see you behind them. Give YOURSELF a chance.

    So these people are wanting the government to mandate even more rear end guards to prevent deaths? Sounds noble until you realize that these are REAR END guards. That means the truck was struck FROM BEHIND. Pretty sure that there aren’t any instances out there of a semi backing up so fast as to strike a vehicle and kill the occupants. Maybe these folks should be looking more at why the trucks were rear ended in the first place? A traffic fatality is always a bad thing but people need to put the blame where it rightly belongs and not automatically say it was the truck’s fault. You rear end a truck, you did something wrong.
