Specific Service Signs provide information about businesses providing gas, food and lodging to travelers day and night. Business Panels are the individual “logo signs” that provide this information. There are three types of signs included in the program.
A Mainline sign is located on the right-of-way of an interstate highway preceding the intersecting roadways where participating businesses are located. Panels may be a maximum of 60” x 36”, with a mininum letter size of 8” and proportional logos and trademarks. Supplemental messages must be a minimum of 5” tall.
A Ramp sign is located near the end of the exit ramp to indicate the direction of participating businesses. Panels may be a maximum of 30” x 18”, with a minimum letter size of 4” and proportional logos and trademarks. Supplemental messages must be a minimum of 2 1/2” tall.
A Trailblazing sign is installed if additional directional signing is needed on the intersecting roads.
Business Panels may feature a logo, trademark, or business name, but no more than one at a time. Supplemental messages such as DIESEL, 24 HOURS, CLOSED (with days of the week), ALTERNATIVE FUELS and RV ACCESS may also be used.
Highway agencies that elect to use Specific Service Signs are required to establish a signing policy. Requirements vary by state, so contact your local highway department for more information.
Complete Specific Service Sign guidelines are listed in the MUTCD.
