Below is the law. Right turn on red must yield to others lawfully using the intersection. If they are left turning into the right hand lane, against the law posted above, they aren't lawfully using the intersection are they? But be cautious, there are uninformed idiots out there and it's the law.

3. Steady red indication:

a. vehicular traffic facing a steady circular red signal alone shall stop at a clearly marked stop line, but if none, before entering the crosswalk on the near side of the intersection or, if none, then before entering the intersection and shall remain standing until an indication to proceed is shown except as provided in subparagraphs b and d of this paragraph,

b. except when a sign is in place prohibiting a turn, vehicular traffic facing any steady red signal may cautiously enter the intersection to turn right or to turn left from a one-way street into a one-way street after stopping as required by subparagraph a of this paragraph. Such vehicular traffic shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection,
