When a red signal is illuminated with rapid intermittent flashes, the operator of any vehicle shall stop before entering the nearest crosswalk at an intersection or at a stop line when marked, or, if none, then before entering the intersection, and the right to proceed shall be subject to the rules applicable after making a stop at a stop sign.
(b) Flashing Yellow Indication. When a yellow signal is illuminated with rapid intermittent flashes, the operator of any vehicle may proceed through the intersection or past such signal only with caution.
