An episode of the television program Forensic Files about an automobile accident that had occurred on Interstate 75 (an Interstate where its northern terminus is in Sault Saint Marie, Michigan and the international U.S-Canada border there, and its southern terminus is in Miami Lakes, Florida-a town near the Everglades) as a result of man made fog produced by a manufacturing plant nearby and the fog had settled in the nearby valley in Tennessee that Interstate 75 traverses through, causing motorists to engage in a gruesome multi-vehicle collision and killing nearly all of these motorists involved.

This time in 1990 was the first time since the 1970’s when there was a fog-induced vehicle collision on this stretch of Interstate 75 that runs through Tennessee; when a law passed by the Tennessee state legislature in the 1970’s mandated that every vehicle titled and registered in the State of Tennessee must be equipped with fog lights (even it means that the owner is required to add on aftermarket ones on a car that has never been equipped with them from the factory), and this fog light mandate had seemingly averted any fog-induced vehicle collisions caused by natural fog that settles in the valley for the next 15 years until this incident that is the subject of this particular episode of the television program Forensic Files.

In the end, it was discovered that the manufacturing plant located nearby had failed to install the filters on their smokestacks that minimize fog and pollutants.
