Our City is looking to establish some regulations on electronic messageboard signs. Over the past year they have reached a price point where every business wants one. No longer used for time and temperature, these things have animations, video, and lots of colors. Can anyone direct me to some decent regulations? We are looking for minimum time that messages must hold (thus eliminating scrolling or animated messages). Does anyone have recommendations as to how long a message should hold? 3 seconds? 10? Or should it be based on the speed limit of the road?
Any input would be greatly appreciated.
