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 2018 not all states have adopted these provisions, with some states (such as
California and
New York) continuing to restrict the installation of logo signs to rural highways only. As of 2018, logo signs are permitted on urban highways in 18 states, with Tennessee being the most recent state (as of 2015) to repeal the restriction for installing logo signs on rural highways only. The 2000 MUTCD also added the attractions category, followed by the 2003 MUTCD which added the 24-hour pharmacies category. 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. In
E-470 on Colorado, the label "ATTRACTION" is replaced by "BUSINESS". In California, as well as on the
Pennsylvania Turnpike the label "GAS" is replaced by "FUEL".
