(2) 
Yellow. While the yellow lens is illuminated no waiting driver of any vehicle shall proceed until the green lens is illuminated, and any driver of a vehicle approaching the intersection who can stop said vehicle with safety before reaching the intersection or a marked stop line shall stop at such point; provided, however, that if a right, left or vertical green arrow is illuminated at the same time a driver may enter the intersection to make the movement permitted by the green arrow or arrows.

While the green lens is illuminated, the driver of a vehicle facing the signal may proceed in any direction, notwithstanding the use or not of any special right, left or vertical green arrow lens which may be incorporated in such signal.
