Rules for billboards and other advertising signs on highways

If you're planning to install a billboard or business sign visible from a state highway, you'll need to make sure that they are properly permitted and follow applicable federal and state laws. We can also point you in the right direction for advertising in state highway rest areas and on Washington State Ferries.
