A gold color metal and enamel device 1 3/16 inches (3.02 cm) in height overall, consisting of a gold steering wheel with four spokes and light blue rim, the four interstices and hub brick red all below two gold arched scrolls one above the other and bearing a gold fleur-de-lis finial, the scrolls inscribed "REX VIAE" in black letters.
Brick red and golden yellow are colors traditionally associated with Transportation. The battalion's five campaign awards for service in the European Theater, World War II are commemorated by the fleur-de-lis and five brick red areas. The organization's origin as a Quartermaster Truck Regiment is depicted by the blue rim of the wheel. The steering wheel refers to the motor transport mission of the unit, and in addition the radiant spokes denote capability for direct support of the tactical units, depot and terminal operations and line hauls. The arched scrolls and finial connote a crown and allude to the translation of the motto, "REX VIAE," King of the Road.
The distinctive unit insignia was approved on 24 October 1967. It was amended to include metric measurements and revise the symbolism of the design on 14 October 1992.
