What color is typically used for warning signs in traffic control?

The color yellow is typically used for warning signs in traffic control because it is highly visible and signals caution. Yellow is associated with alertness and is effective in drawing attention, particularly in situations where drivers need to be aware of changes in road conditions, hazards, or potential dangers. This color is universally recognized for conveying warnings about things such as construction zones, slow-moving vehicles, or other road hazards, and it helps to ensure that motorists remain vigilant while driving in these areas. The bright and eye-catching nature of yellow makes it an essential choice for communicating safety information effectively.
