What color are regulatory signs generally?

Regulatory signs are typically white with black, red, or green lettering, making them highly visible and easy to understand. This color scheme is intentional, as white and black combinations or the use of red is designed to convey important information regarding rules that must be followed by drivers. For example, stop signs are red with white lettering, and speed limit signs are white with black numbers. This consistency in color and design helps ensure that drivers can quickly recognize and comprehend the regulations being communicated on the road.

Other colors mentioned are associated with different types of information. Orange signs are mainly used for construction and maintenance warnings, yellow indicates caution and general warning, and blue is often seen for services and informational purposes. These distinctions in color help create a clear system of communication for drivers, ensuring that each sign type can be recognized and followed effectively.
