Yellow Freight Symbol of Safety 1968 Sticker

In 1906, Grover 'Cleve' Harrell started what was to become the Yellow Cab Company with horse-drawn carriages in Oklahoma City. Harrell's older brother, A. J. arrived, soon followed by their younger brother Marvin, and the three went into business together. In 1929, the Harrell brothers established Yellow Transit Freight Lines to serve small manufacturers for whom express rates were prohibitive. Eventually the partnership dissolved, and A. J. took control of the freight lines, which he kept small until 1952 when an ownership group bought the freight company. During this time, Yellow pioneered the concept of consolidating small shipments into trailer loads. In 1968, the company name was changed to Yellow Freight System.
