Aaron’s team has continued to develop trailer underride guards.  Recently, they crashed a reinforced trailer with a 2012 Chevy Impala at 38 mph and approximately 25% overlap.  This test illustrated that bolt on reinforcements can prevent deadly underride and passenger compartment intrusion (PCI).

Now that we have proof that these lightweight aluminum plates can prevent deadly underride, should we simply encourage voluntary adoption of this life-saving safety solution? Or should we require every truck in the U.S. to install safety equipment which can meet that level of performance?

In other words, are we going to make it the law to install equipment which can prevent underride when passenger vehicles collide with the rear of large trucks?
