What does the color black represent in traffic sign colors?

The color black is commonly used in traffic signs to indicate regulatory messages, such as speed limits and other rules that regulate traffic. This usage is crucial as it helps drivers identify the necessary legal requirements they must follow on the road. For instance, black and white signs are standard for speed limits, which convey important information about the maximum allowable speed for vehicles in a given area, ensuring safety and compliance with traffic laws. This regulatory function is essential for maintaining order and predictability on roadways.

In contrast, colors like yellow typically signify warnings, blue is often assigned for information, and orange is used for construction signs. Each color serves a specific purpose in the traffic sign system, but black is distinctly associated with regulation.
