New York Consolidated Laws, Vehicle and Traffic Law - VAT § 1113. Flashing signal indications

(a) Flashing red indications. Unless to make another movement permitted by other indications shown at the same time, vehicular traffic facing a circular red signal or red arrow with rapid intermittent flashes shall stop at a clearly marked stop line, but if none, then shall stop before entering the crosswalk on the near side of the intersection, or in the event there is no crosswalk, at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway 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 indications. Vehicular traffic facing a circular yellow signal or yellow arrow with rapid intermittent flashes may proceed through the intersection or past such signal only with caution.

(c) Flashing red arrows and flashing yellow arrow indications have the same meaning as the corresponding flashing circular indications, except that they apply only to drivers of vehicles intending to make the movement indicated by the arrow.

(d) This section shall not apply at railroad grade crossings. Conduct of drivers of vehicles approaching railroad grade crossings shall be governed by the rules as set forth in section eleven hundred seventy of this title.
