Horizontal rectangle signs typically provide directions and information about services. These signs are designed to convey useful information to drivers, such as directions to nearby services, points of interest, or other relevant guidance. For example, they may indicate the location of gas stations, rest areas, or attractions.

In contrast, other types of signs serve different purposes: enforceable laws are usually indicated by vertical rectangular signs or regulatory signs, while school zone warnings are specifically marked with unique shapes and colors to alert drivers about school zones. Road work notifications often use diamond-shaped signs to alert drivers to upcoming construction or maintenance activities on the road, emphasizing their warning nature as opposed to providing guidance or directions.
