No..not exactly. There is more than one way to have the tree setup. At the track I go to it is not a redlight unless you go under .000 or - basically. On sactioned events it is pro tree with all 3 ambers going at once with a delay of .500 so anything under that is redlight. Some also run it so that the light come on one at a time( like my track).
