What does a green guide sign commonly signify?

A green guide sign is primarily used for directional guidance and to indicate that movements are permitted in a specific direction. Green is typically associated with information that helps drivers understand where they can go, such as highway exits, mile markers, and distances to destinations. These signs aim to provide clarity and facilitate safe navigation through roadways and intersections.

In contrast, other colors and types of signs serve different purposes. For instance, a general warning sign might indicate a potential hazard or change in road conditions and is often yellow. Guidance for services, such as rest areas or gas stations, might be indicated with blue signs. Red or other colors may denote traffic prohibitions, signaling actions that drivers must avoid. Therefore, the clear function of a green guide sign is to aid drivers with direction and inform them about the permissibility of movements on the road.
