Answer:
When it comes to me, you go on red and stops on green. What am I?
I am longer than a decade and shorter than a millennium
kings and queens may cling to power and the jesters may have their call. I am the most common but I can rule them all.
I twist and turn and leaves a loop
I am partially baked. I am not completely lit. I am a portion of the moon. I am lesser than full wit. I am a divider of the hour. I am not a total lie. I am a sibling through one parent.
What is always coming but never arrives?
