U.S. Can Do Better Than Simply Adopt Canada's Rear Underride Guard Standard

This article contends that a proposed upgrade to rear underride guard regulations for tractor-trailers is not comprehensive enough to achieve the warranted safety gains. The National Highway Traffic Safety Administration (NHTSA) in December issued a notice of proposed rulemaking to require stronger underride guards to stop passenger vehicles from sliding underneath the backs of trailers and semitrailers in rear-end crashes. This proposed rule is partially a response to the 2011 Insurance Institute for Highway Safety (IIHS) petition on this issue. The new proposal brings U.S. regulations in line with stricter ones currently in effect in Canada, but the IIHS is calling for even stronger rules in order to have a greater impact on safety. The article provides statistics on fatalities where large trucks are involved, including those that included passenger vehicles striking the back of a heavy truck or semitrailer (with or without underride). Another section considers the use of small overlap crash testing to help determine the need for different types of vertical supports on trucks. Additional topics covered include trucks that are or will be exempted from the new regulations, and attachment strength certification. Readers are referred to related articles and provided a link to the pdf of the full rulemaking petition under discussion.
