The efforts of the design and engineering team at Stoughton Trailers to improve the design of the trailer rear underride guard has earned the company the ToughGuard Award from the Insurance Institute for Highway Safety and the respect of Marianne Karth, a survivor of a rear-impact crash that took the lives of two of her daughters. On May 4, 2013, Karth was driving her full-size sedan when she was struck by a tractor-trailer, sending her car spinning backward into the rear of another tractor-trailer.
