What do blue road signs typically indicate?

Blue road signs are specifically designed to indicate motorist services. This includes essential amenities such as food, gasoline, lodging, and various other services that can assist drivers during their travel. The standardized use of blue for this type of signage helps ensure that drivers can easily recognize these crucial services when they need them, particularly on long journeys where access to these amenities can be vital.

Understanding the role of color in road signage is important for safe and efficient navigation. In this case, blue stands out as a color dedicated to guiding motorists rather than indicating speed limits, hazards, or directions, which are represented by different colors. This clarity in color coding aids drivers in quickly identifying the resources available to them as they travel.
