What do blue service signs indicate?

Blue service signs are specifically designed to guide drivers to service facilities along the highway. These facilities can include gas stations, restaurants, and lodging, thereby assisting travelers in finding essential services during their journeys. The use of blue for these signs is standardized, making it easy for drivers to recognize the types of services available. Locations indicated by these signs are particularly useful for those seeking roadside assistance or planning stops for food and rest while traveling.
