traffic light colors

Traffic light colors serve as universal signals to manage vehicle and pedestrian movement safely. Green indicates it’s safe to proceed or continue, signaling permission to go. Yellow warns that the light is about to change to red, urging caution and readiness to stop. Red means stop and wait until the light turns green again. These signals help prevent accidents by coordinating flow at intersections, ensuring that all road users understand when it’s safe to move or halt. Proper adherence to these colors maintains order and safety on the roads for everyone.
