What type of traffic sign indicates directions, highway entrances and exits, and distances to upcoming destinations?

Green traffic signs are used to provide information related to directions, highway entrances and exits, and distances to upcoming destinations. They are specifically designed to guide drivers and inform them of the routes they can take, the services available, and how far they are from various locations. This color is commonly associated with signs that direct traffic, such as those indicating mile markers or the approach to an interstate exit, which helps to keep drivers informed and navigate effectively.

In contrast, blue traffic signs typically indicate services such as gas stations or hospitals, rectangular signs can serve a variety of informational purposes including regulations and warnings, and diamond-shaped signs are mainly used for warning drivers about potential hazards or changes in the road conditions ahead. Thus, green signs are the most appropriate choice for providing directional information and distance markers on the road.
