The General Accounting Office (GAO) confirmed in their most recent report, claims what MANY have been saying for 50 years regarding truck underride fatalities.
“There are many and they are under reported.”
The March 26 Crash test Event in D.C. demonstrated how the fatalities can be prevented.
An underride crash occurs when a car slides under a large truck, such as a semi-trailer, during an accident. When these accidents happen, a car’s safety features are rendered useless because most of the car slides under the trailer and the truck crashes straight through the windows and into the passengers. The passengers in the car often suffer severe head and neck injuries, including decapitation. These accidents are often fatal, even at low speeds.
Studies and pilot programs show that a simple barrier attached to the lower area of a truck, called an “underride guard,” would help prevent a car from sliding underneath a truck in an accident. Under current federal law, underride guards are not required to be on the sides or front of trucks. Underride guards are already required for the back of a truck, but the standards are outdated. The bipartisan Stop Underrides Act would require underride guards on the sides and front of a truck and would update the outdated standards for underride guards on the back of trucks.
March 26th 2019 Crash Test Demonstration
The GAO report follows a crash-test demonstration in Washington D.C.
On March 26, 2019, the crash test was hosted by Marianne and Jerry Karth and Lois Durso to demonstrate the efficacy of side underride guards. The tests used Chevy Malibus as the bullet car, striking the side of a tractor trailer at about 30 mph, with and without side underride guards. Industry representatives, and staff members from the Department of Transportation, the Senate commerce committee, and the House Transportation and Infrastructure committee watched as the side underride guards engaged the Malibu, crushing the front end, but leaving the windshield and roof intact

Video on top shows crash test with a fiberglass side skirt intended to improve aerodynamics, not to prevent underride.
The GAO released results of a study to support the consideration of the STOP Underrides Act (S. 666 / H.R. 1511), which would, among other things, require the trucking industry increase its installation of these protective guards. The title of the GAO report, Truck Underride Guards- Improved Data Collection, Inspections, and Research Needed, summed up the report’s central conclusions.
The GAO report contains 46 pages of eye opening information, but what I found most stunning was the number of underride fatalities which were under reported at the scene of the accident. ~Allen Smith~
According to the March GAO report:
From 2008 through 2017, an average of about 219 fatalities from underride crashes involving large trucks were reported annually, representing less than 1 percent of total traffic fatalities over that time frame. However, these fatalities are likely underreported due to variability in state and local data collection. For example, police officers responding to a crash do not use a standard definition of an underride crash and states’ crash report forms vary, with some not including a field for collecting underride data.
Further, police officers receive limited information on how to identify and record underride crashes. As a result, NHTSA may not have accurate data to support efforts to reduce traffic fatalities.
Comparatively, the FARS (Fatality Analysis Reporting System) data show an annual average of about 34,700 total traffic fatalities and approximately 4,000 fatalities involving large trucks over the same period. Therefore, “reported” underride crash fatalities on average accounted for less than 1 percent of total traffic fatalities and 5.5 percent of all fatalities related to large truck crashes during this time frame.
If all underrides were counted accurately, these figures would no doubt be significantly higher.
GAO recommends that DOT take steps to provide a standardized definition of underride crashes and data fields, share information with police departments on identifying underride crashes, establish annual inspection requirements for rear guards, and conduct additional research on side underride guards. DOT concurred with GAO’s recommendations.
U.S. Senators Marco Rubio (R-FL) and Kirsten Gillibrand (D-NY) and U.S. Representatives Steve Cohen (D-TN) and Mark DeSaulnier (D-CA) reintroduced on March 5th 2019,bipartisan, bicameral legislation, the Stop Underrides Act, to help prevent deadly truck underride crashes.
Stop Underride Act Senate bill S.665
Stop Underrides Act House bill H.R. 1511
The bill was first introduced in the Senate in December 2017
–S.2219 – Stop Underrides Act of 2017
AsktheTrucker has written about Underrides in the past and will continue to encourage conversation between truckers, the industry, and proponents for Underrides.
More about the March 26th live crash testing event
The Stop Underrides team of volunteers pulled together to create a memorable live crash testing event a few miles from the nation’s capital. The multi disciplinary group of safety advocates and engineers illustrated how simple semitrailer guards can truly turn what would have been fatal collisions into minor accidents.
Safety engineers and professionals shared their knowledge and thoughts in a Panel Discussion on the underride issue at the D.C. Underride Crash Test Event on March 26, 2019:
- David Friedman, Consumer Reports, VP, Advocacy, formerly the CR Director of Cars and Product Policy and Analysis, former NHTSA Acting Administrator
- Malcolm Deighton, engineer with Hydro, which supplies aluminum for manufacturing underride protective devices and trailer parts and which produces comprehensive underride protection technology in Europe
- Glen Berry, Safety Director for Thomas Transport Delivery, AngelWing installed since 2017, truck driver
- Perry Ponder, inventor of AngelWing, engineer with an accident reconstruction engineering company
- David Dorrity, worked for Stevens Transport for years and testifies all over the country on safe trucking practices.
- Aaron Kiefer, forensic engineer & crash reconstructionist, inventor of SafetySkirt
Moderated by Andy Young, truck litigation attorney and CDL holder.
MGA Research provided crash test dummies and high speed video footage while Collision Safety Consulting (Aaron Kiefer’s company) conducted the tests themselves via custom vehicle tow systems. Hydro NA (OEM supplier to trailer manufacturers) donated engineering personnel and expertise while AnnaLeah and Mary for Truck Safety ALMFTS and StopUnderrides.org conceived and anchored the event. Andy Young MC’d while Glenn Berry donated round trip delivery of a trailer and a power unit for the testing.
The team put together three consecutive side collisions using Chevy Malibu sedans into 53 ft semitrailers. The vehicles were towed into the “T-bone” collisions at or near 30 mph. In order, they crashed a trailer guarded with the Angelwing, a trailer protected by the SafetySkirt, and then an unguarded trailer.
The Angelwing is a steel lattice that fits between the landing gear and dual trailer axles. It is designed by Perry Ponder, manufactured for Airflow Deflector, and currently available for purchase. This guard has been tested during 40 mph collisions, and likely will prevent underride at even higher collision speeds.
The Safetyskirt is a laminated panel that combines a traditional trailer skirt with a woven textile backer that anchors at the landing gear and the rear corner of the trailer to prevent an underride. The system is in development by Aaron Kiefer of TrailerGuards.com. The system looks and feels like a full length skirt that encloses the rear axles for safety and aerodynamic benefit. Testing indicates additional drag reduction (fuel savings) of 2-4% above and beyond current trailer skirts and no issue with negotiating across curbs, medians, or into loading docks. Engineers are working on designing in sufficient access around the axles and wheels for pre trip inspections and tire changes while preserving fuel savings. An owner operator will be conducting over the road testing this summer of a SafetySkirt equipped dry van trailer.
Well engineered guarding solutions are a win-win for drivers and for freight carriers.
On Saturday April 27th at 6PM et we will be having an interview and open discussion concerning Underrides. Guests on the show will be:
Jerry Karth and Marianne Karth and Lois Durso are advocates for Underrides and have lost loved ones due to Underride crashes. Contrary to what many may speculate, these underride deaths were not the fault of either 4 wheeler. One was an improper truck lane change, and the other was icy roads. You can read their stories here.
