What color is used to indicate "go" in traffic signals?

The color green is universally recognized as the indication for "go" in traffic signals. This color signals drivers and pedestrians that it is safe to proceed through an intersection or crosswalk. The use of green for "go" helps maintain consistency in traffic control systems around the world, which is essential for safe navigation and communication on the roads.

In many traffic systems, green signifies the absence of restrictions on movement, allowing vehicles and pedestrians to advance. The association of green with safety and the permission to proceed is rooted in traffic signal conventions established for clarity and safety.

In contrast, red is used to indicate "stop," yellow signals caution or prepare to stop, and blue is not commonly associated with standard traffic control signals but may indicate certain types of information or road signs related to highway services. This understanding of color meanings is vital for anyone involved in traffic signal systems, ensuring they can interpret signals correctly for themselves and others.
