Abstract: At approximately 8:40 a.m. on May 13, 2011, Employee #1, a security guard, was being trained by his supervisor in the operation of a T-3 Motion electric motorized vehicle. The three-wheeled vehicle is designed for a single user, which requires them to stand up during operation. Employee #1 and his supervisor were located in a remote part of a mall parking lot, with Employee #1 practicing the vehicles operation in a figure-eight pattern. He was wearing a bicycle helmet and was instructed to continue in the figure-eight pattern at a slow speed. As Employee #1 rounded one of the turns, he accelerated, causing him to fall from the vehicle. Employee #1 landed on his right side and then rolled to his back. Emergency services were contacted and, upon their arrival, Employee #1 was taken to Scripps Hospital in La Jolla, California, where he was hospitalized and treated for two fractured ribs and a brain hemorrhage, which he underwent surgery for.
