An example of a typical American logo sign
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 (or to a subcontractor of a transportation department such as Lamar Advertising subsidiary Interstate Logos) to have their logos displayed on a large panel alongside other businesses.
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 rural highways. In 2000, provisions for allowing logo signs on urban highways (as long as adequate sign spacing can be maintained) were added to the Manual on Uniform Traffic Control Devices, however, as of 2015 not all states have adopted these provisions, with some states (such as New York) continuing to restrict the installation of logo signs to rural highways only. As of 2015, logo signs are permitted on urban highways in 15 states (Arizona, Colorado, Florida, Georgia, Iowa, Louisiana, Massachusetts, Minnesota, Nevada, North Carolina, Texas, Utah, Virginia, Washington, and Wisconsin). 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 in each direction per interchange. In 2006, the Federal Highway Administration issued an interim approval to allow more than six logo panels per service type on up to two signs per direction, which was eventually incorporated into the 2009 Manual on Uniform Traffic Control Devices.
