Horizontal rectangular signs are primarily used to give what information?

Horizontal rectangular signs are primarily used to provide directions or information. These signs are designed to convey helpful messages to drivers about the route, such as the location of exits, mileage to destinations, or points of interest. They facilitate navigation by offering clear and straightforward visual cues, which helps drivers understand where they are going and what to expect along the road.

In contrast, road regulations are usually indicated by other shapes of signs such as vertical rectangles or circles. Warnings about hazards or unusual conditions are typically represented by diamond-shaped signs. Information regarding services available to motorists, like gas stations or rest areas, is often displayed on specific signs designated for motorist services. Thus, while all these sign types are essential in their respective contexts, the horizontal rectangular signs distinctly serve the purpose of guiding and informing drivers about directions and relevant information regarding the road and travel.
