See picture: All colors have green at the same time. While red and black usually get it on the row, because this black row usually leaves red, it usually pops with the other black line and yellow. Many “yellow” would make it easier to drive first like red and later change the track (a few hundred meters further the 2 tracks are separated in 2 directions). But do I see correctly, in this case has red, if on the yellow driving direction is chosen always advance?! D a it often bangs there, often the vehicles stand there, with what right can I put them together to put their cars aside and then wait for the police or whatever?
