Billboards have been banned in Maine since 1977, when the Legislature voted to prohibit “off-premises” advertising signs. The law took effect in 1978 and required the removal of most existing billboards within several years. It followed Vermont’s earlier example and made Maine the first state on the East Coast to eliminate highway billboards. Businesses may still display signs “on-premises,” and Maine law allows certain “categorical signs,” including noncommercial and religious messages.
