What kind of information does a blue traffic sign typically convey?

A blue traffic sign primarily conveys information related to services. This includes signs indicating various types of facilities or services available to drivers, such as hospitals, food, gas stations, and lodging. The use of blue for these signs is standardized, allowing drivers to easily identify where essential services are located while traveling.

While road condition warnings are typically indicated by yellow signs, directional signs can be found in various colors, often including green. Speed limit regulations are conveyed with white signs that may have black lettering. Understanding the color coding of traffic signs in this manner makes it easier for drivers to quickly interpret the information and navigate efficiently.
