Colors and arrow indications in traffic control signals shall have the commands ascribed to them in this section and no other meanings, and every driver of a vehicle, railway car or other conveyance shall comply therewith, except when otherwise directed by an officer or by a lawful traffic regulating sign (other than a stop sign), signal or device or except as provided in § 220-39. In no case shall a driver enter or proceed through an intersection without due regard to the safety of other persons within the intersection, regardless of what indications may be given by traffic control signals.
A. 
Green. While the green lens is illuminated, drivers facing the signal may proceed through the intersection but shall yield the right-of-way to pedestrians and vehicles lawfully within a crosswalk or the intersection at the time such a signal was exhibited. Drivers of vehicles making a right turn or left turn shall yield the right-of-way to pedestrians crossing with the flow of traffic.
B. 
Right, left and vertical green arrows. When a right green arrow is illuminated, drivers facing such signal may turn right. When a left green arrow is illuminated, drivers facing such signal may turn left. When a vertical green arrow is illuminated, drivers facing such signal may go straight ahead. When a green arrow is exhibited, together with a red or yellow lens, drivers may enter the intersection to make the movement permitted by the arrow but shall yield the right-of-way to vehicles and pedestrians proceeding from another direction on a green indication.
C. 
Yellow. While the yellow lens is illuminated, waiting drivers shall not proceed and any driver approaching the intersection or a marked stop line shall stop at such point unless so close to the intersection that a stop cannot be made in safety; provided, however, that if a green arrow is illuminated at the same time, drivers may enter the intersection to make the movement permitted by the arrow.
D. 
Red. Traffic facing a steady circular red signal alone shall stop at a clearly marked stop line or, 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 allowed by MGL c. 89, § 8.
