What is indicated by the color white on traffic signs?

The color white on traffic signs is primarily used for regulatory purposes. This means that signs using white backgrounds convey essential rules and regulations that drivers must follow. For example, regulatory signs include speed limit signs, which inform drivers about the maximum speed allowed on a particular stretch of road, or no parking signs, which indicate areas where parking is prohibited.

This color is contrasted with others on traffic signs that serve different functions. For instance, yellow is often used for warning signs that alert drivers about potential hazards or changes in road conditions, while red is used to signify stop or prohibition, such as stop signs or yield signs. Green and blue are typically reserved for direction guidance, providing information on routes, distances, or services available. In this context, understanding the function and significance of each color is vital for safe navigation and compliance with traffic laws.
