Studies have been done which show that trucks, even if they are equipped with rear underride guards, do not pass all of the crash tests. In fact, out of 8 truck companies tested, only one passed all of the tests: http://www.iihs.org/news/rss/pr031413.html.
So, it may be a true statement, according to The American Trucking Association, “that many manufacturers are producing trucks with better than required safety underride guards.” http://myfox8.com/2013/08/13/families-push-for-tractor-trailer-regulations/ Nonetheless, the bottomline is that there are many trucks which are NOT equipped with the best possible protection, which means that someone somewhere sometime might crash with one of those trucks and not live to know it.
Why would there be resistance to providing the best possible protection? Is it money? Quite possibly… Yet, according to Manac President Charles Dutil, the Manac underride guard “doesn’t weigh 200 pounds more than anybody else’s; it doesn’t cost $200 more,” estimating the difference to be at most 20 pounds and $20.
“If trailer manufacturers can make guards that do a better job of protecting passenger vehicle occupants while also promising lower repair costs for their customers, that’s a win-win,” says David Zuby, the Insurance Institute for Highway Safety’s chief research officer. http://www.iihs.org/externaldata/srdata/docs/sr4802.pdf
What I want most of all, in this situation, is to help reduce the number of families who open their mail to find a death certificate for a family member because of a preventable death…
