What does a blue road sign typically indicate?

A blue road sign typically indicates information about services available to drivers. These signs are designed to guide motorists to essential services like gas stations, restaurants, hospitals, and lodging. The blue color is standardized in traffic signage to convey such information and help drivers find necessary amenities while traveling.

While hazard information is usually indicated by yellow signs, and directions to nearby landmarks might be represented by different colored signs, blue signs hold a specific purpose in alerting drivers to available services. Speed limit regulations are typically signified by regulatory signs in white and black, reaffirming that blue signs have a distinct role focused on aiding travelers in locating services rather than warning them about conditions or regulations.
