A white square sign is primarily used to convey regulatory information, meaning it provides rules and regulations that drivers must follow. This can include important directives such as speed limits, yielding, stopping, or other traffic regulations that dictate how vehicles should behave on the road. Regulatory signs are essential for maintaining order and safety in traffic as they communicate the laws that drivers are required to obey.

In contrast, warning signs typically use colors like yellow and orange to alert drivers to potential hazards or changes in traffic conditions, while construction zone signs often incorporate specific colors and symbols to highlight roadwork areas. Speed limits, although related to regulatory information, are just one specific aspect of it and are often displayed on the white square regulatory signs, but the broader category encompasses all traffic regulations which is why the identification of a white square sign as indicating regulatory information is accurate.
