A blue sign is classified as informational because it serves to provide travelers with essential information about services and features available in the area, such as hospitals, gas stations, and rest areas. These signs are designed to assist drivers by offering guidance on what amenities may be found nearby, as well as indicating any special conditions that may be pertinent to their journey.

The context for why other types do not apply includes the fact that warning signs usually indicate hazards or changes in road conditions, regulatory signs inform drivers of laws they must follow, and guide signs direct drivers with navigational information. In contrast, blue signs specifically communicate aid and services, making them vital for travelers looking for amenities or assistance.
