What does a blue guide sign provide information about?

A blue guide sign provides information about motorist services guidance. These signs are designed to inform drivers about services available in the area, such as gas stations, rest areas, hospitals, and other facilities that offer assistance to travelers. The use of blue for these signs indicates that they are specifically related to services geared towards helping motorists during their travels.

In contrast, signs indicating school zones, traffic regulations, and general warnings utilize other colors to convey different types of information. For instance, school zone signs typically use fluorescent yellow-green, while traffic regulations are often signified by red or white. General warning signs may use yellow for cautionary messages. Thus, the distinctive use of blue is integral in distinguishing motorist services from these other categories of information.
