What do green signs provide to drivers?

Answer: B — Guidance and information

Green signs are primarily used to offer guidance and information to drivers. They indicate directional guidance, such as the routes to take, mile markers, or distances to various locations. This color is associated with providing essential travel information, helping drivers navigate their routes efficiently. For example, green signs can indicate highway exits, major city destinations, or the distance remaining to a specific location. In contrast, other colors serve different purposes; for instance, yellow signs typically warn of hazards, while orange signs often indicate construction zones. Historical information is not commonly conveyed through traffic signage, which further highlights the unique role that green signs play in assisting drivers.
