Evanston FAQ
Can I convert a static billboard to digital in unincorporated Cook County?

Are flashing or animated messages ever allowed?
No. The Illinois Highway Advertising Control Act bans animation, scrolling, flashing, and video on signs visible from regulated highways. Only static digital messages with eight-second holds and brief two-second transitions comply with state outdoor advertising rules.
