Modifies provisions relating to outdoor advertising

HB 2145 modifies outdoor advertising rules near highways in Missouri. It permits signs within 660 feet of interstate, federal-aid primary, or National Highway System roads - especially in industrial/commercial zones - and sets specific limits: signs cannot exceed 800 square feet (30 ft tall, 72 ft long), must avoid flashing lights (except scoreboards), and must maintain 1,400 feet between structures on the same highway side. The bill directly affects outdoor advertising companies, property owners in commercial zones, and highway safety by restricting sign placement to reduce visual clutter and driver distraction. Existing signs not meeting these rules after 2002 will be considered "nonconforming" but may remain.
