What are the orders of traffic lights?
What are the orders of traffic lights? Traffic signals alternate the right of way accorded to road users by displaying lights of a standard color (traffic light colors: red, yellow/amber, and green) following a universal color code. The traffic light color order is a red light above the green, with the yellow in between (that's a catchy little rhyme).
What are the 4 traffic lights?
Red: Stop. Yellow: Prepare to stop. Green: Go. Flashing red light: Come to a complete stop and yield to oncoming traffic or pedestrians.
