Which color of traffic signs is used to display traveler information to drivers?

Blue traffic signs are specifically used to convey traveler information to drivers. This includes information related to services such as hospitals, gas stations, rest areas, and other points of interest that are beneficial for travelers. The blue color is chosen for these signs because it is easily recognizable and typically denotes information that is helpful in navigating to various destinations or services.

In contrast, brown traffic signs are used to indicate recreational or cultural points of interest, green signs generally provide directional guidance or distance information, and yellow signs usually signify caution or warn drivers about temporary conditions ahead. Each color serves a specific purpose in the overall traffic sign system, helping to ensure clarity and safety on the road.
