What does the color yellow typically signify in traffic management?

The color yellow in traffic management typically signifies the need to proceed with caution. This is a universal color code indicating that a situation is potentially hazardous and that drivers and personnel should be alert and ready to respond accordingly. In many traffic systems, a yellow light suggests that the signal is about to change, urging individuals to slow down and prepare to stop if necessary.

This cautionary color helps to prevent accidents and ensures a smoother flow of traffic by alerting individuals to be vigilant. In contexts like airport ground traffic, it may indicate that an aircraft or vehicle should proceed with care, maintaining awareness of their surroundings and being prepared for any unexpected developments. Such use of the color yellow plays a critical role in enhancing safety and management in various traffic situations.
