What color represents a regulatory sign such as a speed limit?

Regulatory signs, like speed limit signs, are essential for maintaining traffic laws and ensuring the safety of all road users. The color most commonly used for these signs is a combination of white, which provides a clear and neutral background, and black for the text and symbols. This combination is easily readable and conveys important information about the rules drivers must follow.

This design choice ensures high visibility under various conditions, allowing drivers to quickly recognize and respond to the information presented. Other colors, such as red, are often used for signs indicating prohibition or warning (like stop signs), while yellow typically warns of caution, and green is associated mainly with guidance signs, which provide directional information. Consequently, the use of white and black for regulatory signs ensures that they effectively communicate essential traffic regulations to drivers.
