Most cities and towns don't allow LED boards that aren't a dedicated billboard to be used for off premise advertising. This is a thing that constantly comes up from people interested in buying LED boards to install on street
signs -"we can make a bunch of money selling ad time and let that pay for the LED board!" Uh, not really. Billboards, whether they're next to the highway or installed along a city street, require their own permits. I could be wrong, but I'm pretty sure LED billboards in Oklahoma have a state-wide standard of static ads with a minimum 8 second hold time. A huge casino
sign can show full motion video on a giant LED board, but it's an on-premise
sign.
