What type of signs are used to convey information related to motorist services?

Blue guide signs are specifically designed to convey information related to motorist services. These signs typically indicate the locations of services such as fuel stations, restaurants, lodging, and other amenities that are available to travelers. Their distinctive blue color is standardized to help drivers easily recognize these critical services while on the road, enhancing safety and convenience.

In contrast, the other sign types serve different purposes. Brown guide signs provide information about recreational and cultural points of interest, while yellow warning signs alert drivers to potential hazards ahead. Red regulatory signs communicate important traffic regulations that must be followed by drivers, such as stop signs or yield signs.
