On Interstate 15 in California, the driver of a heavy weight continued to roll over 6 kilometers without realizing that a Nissan Maxima car was accidentally attached to one of its trailers. The driver of the sedan was great signs by the window to ask the driver to stop, but noticed nothing, and continued on his way. Fortunately, other motorists came to the rescue of the driver in distress by placing their vehicles in front of the truck to stop its progression.
