Regulations of Connecticut State Agencies
The following meanings shall be given to highway traffic signal indications, except those on pedestrian signals:
(a) Green indications shall have the following meanings:
(1) Traffic facing a circular green may proceed straight through or turn right or left except as such movement is modified by lane-use signs, turn prohibition signs, lane markings or roadway design. But, vehicular traffic, including vehicles turning right or left, shall yield the right-of-way to other vehicles and to pedestrians lawfully within the intersection or an adjacent crosswalk, at the time such signal indication is exhibited.
(2) Traffic facing a green arrow, shown alone or in combination with another indication, may cautiously enter the intersection only to make the movement indicated by such arrow or such other movement as is permitted by other indications shown at the same time. Such vehicular traffic shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other trade lawfully using the intersection.
(3) Unless otherwise directed by a pedestrian signal, pedestrians facing any green indication, except when the sole green indication is a turn arrow, may proceed across the roadway within any marked or unmarked crosswalk.
(b) Steady yellow indications shall have the following meanings:
(1) Traffic facing a steady circular yellow or yellow arrow signal is thereby warned that the related green movement is being terminated or that a red indication will be exhibited immediately thereafter when vehicular traffic shall not enter the intersection.
(2) Pedestrians facing a steady circular yellow or yellow arrow signal, unless otherwise directed by a pedestrian signal, are thereby advised that there is insufficient time to cross the roadway before a red indication is shown, and no pedestrian shall then start to cross the roadway.
(c) Steady red indications shall have the following meanings:
(1) 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 (2) below.
(2) Except when a sign is in place prohibiting a turn, vehicular trade facing any steady red signal may cautiously enter the intersection to turn right after stopping as required by (1) above. Such vehicular traffic shall yield the right-of-way to pedestrians and other vehicles lawfully using the intersection.
(3) Unless otherwise directed by a pedestrian signal, pedestrians facing a steady circular red signal alone or red arrow signal alone shall not enter the roadway.
(4) Vehicular traffic facing a steady red arrow signal shall not enter the intersection to make the movement indicated by the arrow and, unless entering the intersection to make a movement permitted by another signal, 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 permitting the movement indicated by such red arrow is shown except as provided in (2) above.
(d) Flashing signal indications shall have the following meanings:
(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, 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.
(2) Flashing yellow (caution signal) - when a yellow lens is illuminated with rapid intermittent flashes, drivers of vehicles may proceed through the intersection or past such signal only with caution.
(3) Flashing red arrow and flashing yellow arrow indications have the same meaning as the corresponding flashing circular indications; except they apply only to drivers of vehicles intending to make the movements indicated.
