What color road sign is typically used to manage traffic regulation?

The color red is commonly associated with road signs that convey important regulatory information, particularly those that indicate stop, yield, or prohibitory messages. Red signals drivers to take immediate action, such as stopping at a stop sign or yielding at a yield sign, helping to maintain safety and order on the road. The use of red for these purposes is universally recognized and is meant to grab the driver's attention quickly.

Other colors serve different functions: yellow typically signals caution or warnings about conditions ahead, green is used for guidance and directional information, and white generally denotes regulatory signs as well. However, red's unique role in conveying direct commands makes it the primary color associated with traffic regulation enforcement.
