This synthesis will be of interest to traffic engineers, planners, and others interested in providing directional guidance to motorists. Information is provided on policies and procedures used by many states in establishing and operating signing programs that provide information on available motorist services and tourist attractions. On Interstate and other controlled-access highways, signs that show the logos of nearby gas, food, lodging, and camping facilities provide valuable assistance to motorists. This report of the Transportation Research Board describes the policies and procedures used by states to install and maintain those signs as well as other types of signs that direct motorists to tourist services and attractions.  The report for this topic can be purchased at https://www.trb.org/news/blurb_detail.asp?id=3395
