The official slow moving sign we are all familiar with in the USA (triangle) is to be used on vehicles going "really" slow not just slower than the rest of the herd! I don't know if its legal to display one on any vehicle just because someone is going slower than the rest of the traffic.
It would be illegal in IL.
625 ILCS 5/12-709. Slow-moving vehicle emblem.
