I worked for 20 years in one with 80,000 odd employees and despite working with radioactive sources, explosives and really nasty chemicals and lots of high energy mechanics most (basically all) of the accidents and deaths in the company came from vehicle accidents and half of them low speed reversing incidents. Whilst some were reversing trucks during work processes, many were just people reversing over each other outside of work. Because of the cost of human fatalities in both $ terms, lost productivity and way too much paperwork, (there were in the order of 10 per year) and injuries (lots) they spent a great deal of time and money on educating and enforcing employees to reverse park at all times. In fact, we were trained to never reverse, pretend the vehicle had no reverse gear and if we really had to reverse we had to have a spotter, else we just didn't park in that spot. According to the National Highway Traffic Safety Administration (NHTSA estimates that “267 people are killed and 15,000 injured each year by drivers who back into them, usually in driveways or parking lots.” Unfortunately, most often it is children and elderly people who are killed in backover crashes.
