A white rectangular sign is used primarily to convey regulatory information to drivers. This type of sign often presents essential guidelines regarding traffic laws and regulations that must be followed, such as speed limits, stop signs, or yield signs. These signs are critical for ensuring that drivers understand the legal expectations while on the road, helping to maintain order and safety within the traffic system.

In contrast, warning information is usually indicated by yellow diamond-shaped signs, which alert drivers to potential hazards or changes in road conditions. Informational guidance is often provided through green or blue signs, indicating directions, distances, or services available. Construction alerts are typically conveyed through orange signs, signaling road work or temporary changes in driving conditions. Each type of sign serves a distinct purpose, but the specific use of white rectangular signs as regulatory indicators helps to enforce the rules that all motorists must adhere to for safe driving.
