Several US states restrict or ban outdoor advertising billboards, affecting what drivers will see on road trips. According to reporting compiled from different outlets, Hawaii, Maine, and two additional states pursue billboard controls through long-running campaigns, regulatory limits, or laws aimed at reducing commercial visual clutter.

In Hawaii, sources point to an early, century-old effort that shaped later restrictions by emphasizing protection of natural landscapes rather than advertising revenue. Maine is described as taking a particularly strict approach: reporting indicates a law required significant removal of existing signs, including the cutting down of thousands of billboards.

Elsewhere, the remaining states’ policies are characterized as limiting the placement or size of billboard advertising, with the stated rationale focused on preserving scenic views and the appearance of highways and communities. The shared theme across the sources is that these rules reduce the presence of large commercial signs along roads, even as they differ in how they arrived at current levels of restriction.
