Introducing the "Did You Know?" series! This week we're looking at when and where you can place signage. No unauthorized person shall erect or maintain upon any highway, any warning or direction sign, marker, signal, or light in imitation of any official sign, marker, signal, or light. In addition, no person shall place or maintain nor shall any public authority permit any traffic sign or signal bearing any commercial advertising upon any highway. A violation of this section is a Class 2 misdemeanor. For additional information on illegal signage, please visit https://lnkd.in/dkGd6chV.
