My recommendations for the IIHS Underride Roundtable in August.

I do not support the efforts of the Underride Roundtable as they support killer stiff underride guards and have given awards to these old technology instruments of death! My recommendations for front underride issue coverage at Roundtable below:

You will have to look to Europe for front underride experts, unfortunately.


Your best bet for links to experts and front underrun design advocacy is the European Cyclists Federation.


Issues are cab visibility, pedestrian and vehicle detection systems, truck weight and speed, automatic braking, underride guards, and softening and shaping the front of the vehicle. Roadway design is critical for front underrun as front head-on crashes are the leading killers in car-to-truck crashes. When you separate directional traffic into separate lanes with sufficient separation to reduce headlight glare you drastically reduce fatalities and severe injuries.

I am seeing increasing cow catchers on the front of trucks in the U.S. including pickups and SUV’s which are pedestrian killer’s and hardened crash systems for other softer vehicles.

Extending European vehicle length regulations for extending underride guards to work at high speeds, if we do not extend guards they simply do not protect in high-speed crashes, period!

According to Chalmers Car-to-Truck Frontal Crash Compatibility Report increasing the length of the underrun guard away from the truck body increases the critical impact speed it can provide protection for:

To 95 km/h (59 mph) with a 300 mm – length HC structure (+27%)
To 102 km/h (63 mph) with a 600 mm – length HC structure (+36%)
To 107 km/h (67 mph) with a 900 mm – length HC structure (+43%)

This extra space increases the stroke distance available for energy absorbing material to absorb vehicle crash energy. In high-speed crashes it is critical to shape the truck to direct the car away from the truck by directing spin so vehicle has less impact with truck and thus less crash energy.


Truck Underride Roundtable

SAVE THE DATE: Tuesday, August 29, 2017

Organized and sponsored by IIHS, the Truck Safety Coalition, and AnnaLeah & Mary for Truck Safety
Please join us on Tuesday, August 29, 2017, for the second Truck Underride Roundtable. The focus of this year’s meeting will be preventing side underride. Researchers, government officials, and industry leaders will explore the scope of the problem and discuss how regulation and voluntary action can help address it. There will also be a crash test demonstrating performance of a side underride guard.

TIME: 9:00 AM to 3:00 PM
LOCATION: IIHS Vehicle Research Center in Ruckersville, Virginia

There is no registration fee, and lunch will be provided. Agenda and additional details to follow. Please RSVP to Chamelle Matthew at or +1 703 247 1535.

Our Roundtable Partners


Annaleah and Mary for Truck Safety
Dedicated to preventing more deaths from happening in truck-related crashes. Specifically, the Karth family is working to raise awareness about three issues related to truck safety: driver fatigue, minimum liability insurance levels and underride guards.

The Truck Safety Coalition
The Truck Safety Coalition is dedicated to reducing the number of deaths and injuries caused by truck-related crashes, providing  support to truck crash survivors and families of truck crash victims, and educating the public, policy-makers and media about truck safety issues.
