Rules, Permits & Restrictions

What the law allows on billboards and other outdoor media in the U.S. — a plain-English overview.

Federal: the Highway Beautification Act

The Highway Beautification Act of 1965 requires states to control billboards along Interstate and federal-aid primary highways, generally limiting them to commercial and industrial zones and setting standards for size, lighting and spacing. States enforce it through their own outdoor advertising permits, and federal highway funds are tied to compliance.

State & local rules

  • State DOT permits are required for most roadside billboards along controlled highways.
  • Local sign codes govern zoning, size, height, spacing and lighting; some cities restrict or prohibit new billboards entirely, and a few states (Vermont, Maine, Alaska, Hawaii) largely ban them.
  • Digital billboard rules typically require a minimum message duration (often 6–10 seconds), instant transitions, no motion or video, brightness limits and automatic dimming at night.
  • Street furniture and transit are governed by city and transit-authority contracts, which also set content standards.
  • Mobile billboards, aerial and projection may need city permits, FAA waivers or property-owner consent.

Vendor & transit-authority standards

Media owners and transit agencies apply their own copy-acceptance policies and can reject creative that is misleading, explicit, or that falls into categories they've chosen not to carry. Submit creative early so there's time for revisions.
