(2) 
When a sign is in place permitting a turn, drivers facing a steady circular red signal may cautiously enter the intersection to make the turn indicated by such sign after stopping as provided in Subsection C(1) above. Such drivers shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.

(1) 
Flashing red (stop signal). When a red lens is illuminated with rapid intermittent flashes, drivers of vehicles 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 at the point nearest the intersecting roadway where the drivers have a view of approaching traffic on the intersecting roadway before entering the intersection, and the right to proceed shall be subject to the provisions of MGL c. 89, § 8.
