A 28-year old straight truck driver badly hurt her ankle when she slipped from a cargo box.
The driver's job required climbing up and down from a cargo box all day to deliver goods. During a stop, the driver got in the box and moved some freight near the door to load onto a hand truck parked on the ground. When she stepped down from the rear deck she became distracted, lost footing, and slipped off. She landed on her left ankle. The ankle twisted and swelled up in sharp pain.
