What do you call a sign that provides information about road conditions or directions?

The correct answer describes a sign that primarily helps drivers navigate and understand their surroundings while traveling. Guide signs are designed to give information about directions, locations, and points of interest, such as upcoming exits, mile markers, and service areas. They are typically green and provide crucial information that assists drivers in planning their routes and finding destinations.

In contrast, warning signs indicate potential hazards or changes in roadway conditions, often using yellow backgrounds, to alert drivers to take caution. Regulatory signs enforce laws and regulations, such as speed limits or stop signs, and are usually red, white, or black in color. Informational signs may also convey useful information, but they are not standardized and can vary widely in content and design compared to the specific purpose of guide signs.
