What does a blue traffic sign generally indicate?

A blue traffic sign generally indicates guide information or services. These signs are designed to provide drivers with useful information, such as directions to services (like gas stations, hospitals, or rest areas), tourist attractions, and other amenities that can assist motorists.

This color coding helps to quickly relay the type of information that is being presented without the need for elaborate explanations. For instance, a blue sign pointing toward a hospital would allow drivers to easily recognize that medical assistance is accessible in that direction. The use of blue as a standard for guide signs ensures consistency across various regions, allowing drivers to approach these signs with a familiar understanding of what type of information to expect, enhancing both navigation and road safety.
