This bill establishes a new requirement for the Washington State Department of Transportation to create and maintain a publicly accessible map that outlines where temporary political campaign signs can be placed along major roadways, including the interstate system, primary system, and scenic system. The map will detail locations on department-owned or managed land, areas where signs are prohibited due to state highway right-of-way, and any adjoining private or public land where signs are allowed.

Additionally, the map must be easily accessible on the department's website, ensuring that the public can readily find information regarding sign placement. Importantly, the department is restricted from removing any campaign sign unless it is clearly indicated on the map that the sign is located in a prohibited area. This legislation aims to provide clarity and transparency regarding the placement of political signage, thereby facilitating compliance with state regulations.
