What do blue traffic signs indicate?

Blue traffic signs are used primarily to provide information regarding services available to drivers, such as rest areas, gas stations, hospitals, and other essential facilities. The blue color is meant to convey a calm and informative tone, allowing drivers to quickly identify services they may need while on the road.

In contrast, other types of traffic signs serve different purposes; for example, warning signs typically use colors like yellow or orange to indicate hazards or changes in road conditions, while regulatory signs, such as those indicating speed limits, commonly feature colors like red or white. Moreover, stop locations are indicated using octagonal red signs to ensure they stand out and grab attention. Understanding the specific meanings associated with color and shape in traffic signage is crucial for safe driving and navigation.
