The STOP Underrides! Act of 2017 will get the ball rolling so that creative engineers can put effective underride protection on every truck — resulting in more truck crash survivors who can live to see another day.
This bill has been drafted by Senator Kirsten Gillibrand. On December 12, 2017, Senator Gillibrand, Senator Rubio, and Congressman Steve Cohen will be introducing it in Congress. They are all seeking Republican co-sponsors for this long-overdue, life-saving legislation.
Beginning on December 11, 2017, please SIGN & SHARE the STOP Underrides! Bill Petition: COMING SOON!
On October 12, 2017, staff from Congressional Offices gathered to hear presentations from five experts on the topic of truck underride to better understand the need for the STOP Underrides! bill. The presentations were followed by a question & answer period as legislative staff sought to understand the problem and solutions of deadly but preventable underride crashes.

Efforts in 2016 to improve underride prevention:
- International Call for Underride Research Re: Injury Prevention & Energy Absorption Issues I put together another request for underride design proposals. I would like to be a little bit more specific and put out a call for research and data to put to rest, once and for all, the controversy over underride guard rigidity/strength and the potential for unintended injuries from too rigid guards. I would like to see it result in data which could lead to design of the best possible underride protection and practical solutions for underride guards to incorporate energy absorption components where appropriate.
- Knights of the Underride Roundtable: Finding Some Common Ground to Protect Travelers! On June 24, 12 people from diverse backgrounds met around a table at the IIHS offices in Arlington, Virginia, to continue the good work begun at the Underride Roundtable on May 5, 2016. This time, we rolled up our sleeves and hammered out a written recommendation for better rear underride guard requirements for tractor-trailers. To save lives.
On May 5, 2016, over 65 representatives from the trucking industry, government, safety advocates, engineers, crash reconstructionists, attorneys, and media met at the Insurance Institute for Highway Safety’s Vehicle Research Center to discuss and demonstrate truck underride crashes.

Underride Guard Fact Sheet
An underride guard, currently required on most motor carriers, is fastened below the bed of the trailer. Its purpose is to prevent a car from riding under the truck in the event of a collision. In the case of our crash, as all too often happens, the guard did not hold up and the rear of our vehicle went under the truck.
Photo: Our truck crash with rear underride, May 4, 2013: AnnaLeah & Mary were in the backseat, when our car was pushed backward under the tractor-trailer by another truck, and they did not survive.
This post summarizes our efforts in the aftermath of the crash to bring about a National Vision Zero Goal–moving our country closer to reducing crash deaths and serious injuries: Are you aware that Death by Motor Vehicle is one of the leading causes of death?
We witnessed some crash tests on March 12, 2016, in North Carolina: Witnessed safety defect in action at underride crash tests; this is what snuffed out my daughters’ lives.
Past news: We looked forward to the first Underride Roundtable at the IIHS Vehicle Research Center in Ruckersville, Virginia: Underride Roundtable Registration Now Open: May 5, 2016 at IIHS Vehicle Research Center

In addition, Jerry and I were invited to tour the research facility of one of the major trailer manufacturers, Great Dane, in June 2014. After our visit, I wrote a post and created a Youtube video to summarize my reactions. My thoughts are expressed below and are also published as a YouTube video–which can be found at the end:
“I find myself in the unenviable position of speaking up on behalf of all travelers on the road who are vulnerable and could—when they least expect it—become the next victim of an underride crash.
Jerry and I had the opportunity, on June 25, to tour the Research & Design Center of Great Dane, a trailer manufacturer. As their guests, we were able to spend the entire morning hearing about what they are doing with regard to quality control and safety, including underride guards which they voluntarily produce to meet or even exceed Canadian standards—thus surpassing current U.S. federal standards. We were able to ask questions and share our concerns about the inadequate federal standards for underride guards (otherwise known as rear impact guards).
We are perhaps better suited to ask those questions than just about anyone. After all, we had two daughters die because the car they were in rode under the back of a semitrailer .”
From that post: “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.”
