The Department of Transportation has regulations for underride guards on trailers. You know what I mean, that thing we have been talking about: the guard on the back of trailers which is supposed to keep a vehicle from sliding under the truck in the event of a crash.
But, too often, these guards don’t do what they are supposed to do. What if there was a better design/better standards than what is currently required? What should we do about it?
Study these photos for yourself. The top trailer has a different design and, in a crash test, the results were significantly different.
