What does it mean if a traffic sign is rectangular?

A rectangular traffic sign primarily serves as an informational or guide sign. These signs are designed to provide drivers with crucial details about directions, distances, and services, as well as other general information related to roadways. For example, a rectangular sign might indicate that a road is ahead or provide mileage to a nearby city.

Regulatory signs, while they can also be rectangular, typically are either vertical rectangles or squares that convey specific rules or regulations that must be followed, emphasizing the distinction in their function compared to guide signs. Hazard warning signs, which usually take on a diamond shape, specifically alert drivers to potential dangers or changes in road conditions. School zone signs are often unique in shape and color, specifically designed to alert drivers to the presence of children, rather than following the standard rectangular format.
