Abstract: A vehicle sign assembly includes a pair of elongated sign boards that are attached to a tow vehicle pulling a towed vehicle. The signs protrude away from side doors of the tow vehicle so that they are visible. Each sign has three transparent sides. One side is abutted against the tow vehicle while second and third sides converge outwardly from the tow vehicle doors so that the signs can be seen from a front and a rear of the tow vehicle. The second and third sides include indicia printed thereon, signaling that a vehicle is being towed. Each sign includes a chamber formed between the sides thereof. A mechanism is included for illuminating the signs so that one sign can remain illuminated when another sign is non-illuminated. A mechanism is included for affixing the signs to the doors of the tow vehicle such that signs can be adjusted as needed.
