What kind of information does a horizontal rectangle sign provide?

A horizontal rectangle sign primarily serves the purpose of providing guide information, which includes important details about locations, directions, and services available in the area. These signs help drivers navigate and find their way, often indicating things like city names, distance to various destinations, or locations of amenities such as gas stations and rest areas.

The format of a horizontal rectangle is specifically chosen for its clarity and ease of readability from a distance, making it suitable for directional guidance. Other types of signs, such as circular or octagonal signs, serve different purposes, such as regulatory or warning signs, while horizontal rectangle signs focus exclusively on guiding and informing road users about their surroundings.
