Logo signs (also known as specific service signs or Logo service signs) are blueroad signs used on freeways that display the logos of businesses prior to an interchange. Typically, a business pays fees to a transportation department to have their logos displayed on a large panel alongside other business.
In the United States, logo signs were permitted on rural Interstates in 1965 as part of the Highway Beautification Act. Originally, such signs were limited to the following categories: gas, food, lodging, and camping. The 1976 amendments to the Highway Beautification Act expanded the program to federal-aid primary highways. In 2000, the federal restriction of logo signs to rural areas was lifted, although state laws still vary on whether or not logo signs can be installed on urban highways. In 2003, two new categories were added to the standard: attractions and 24-hour pharmacies. Logo signs in the United States are limited to six logos per sign, and additional signs may be used up to a total of four per interchange.
