 Vermont is one of four states, along with Alaska, Hawaii, and Maine, to have prohibited by law all billboards from view of highway rights-of-way, except for signs on the contiguous property of the business location.After the legislature was redistricted under one-person, one-vote, it passed legislation to accommodate American emigrants from New York, which earlier legislatures had ignored.The new legislation was the Land Use and Development Law (Act 250) in 1970.
