474.630. - Traffic control signal.
(a) Whenever traffic is controlled by traffic control signals exhibiting different colored lights, or colored lighted arrows, successively one (1) at a time or in combination, only the colors green, red and yellow shall be used except for special pedestrian signals carrying a word legend or symbol. The lights shall indicate and apply to drivers of vehicles as follows:
(1) Green indication:
a. Vehicular traffic facing a circular green signal may proceed straight through or turn right or left unless a sign at such place prohibits either such turn. But vehicular traffic, including vehicles turning right or left, shall yield the right-of-way to other vehicles and pedestrians lawfully within the intersection or an adjacent crosswalk at the time such signal is exhibited.
b. Vehicular traffic facing a green arrow signal, 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 traffic lawfully using the intersection.
(2) Steady yellow indication:
a. Vehicular traffic facing a circular yellow 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, except for the continued movement allowed by any green arrow simultaneously indicated.
b. Vehicular traffic facing a steady yellow arrow signal is thereby warned that the protected vehicular movement permitted by the corresponding green arrow indication is being terminated.
(3) Steady red indication:
a. Vehicular traffic facing a circular red signal alone shall stop at a clearly marked 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 a green indication is shown, except as follows:
1. The driver of a vehicle which is stopped as close as practicable at the entrance to the crosswalk on the near side of the intersection or, if none, then at the entrance to the intersection in obedience to a red or stop signal, and with the intention of making a right turn may make such right turn, after stopping, unless an official sign has been erected prohibiting such movement, but shall yield the right-of-way to pedestrians and other traffic lawfully proceeding as directed by the signal at said intersection; or
2. The driver of a vehicle on a one-way street which intersects another one-way street on which traffic moves to the left shall stop in obedience to a red or stop signal and may then make a left turn into said one-way street, unless an official sign has been erected prohibiting the movement, but shall yield the right-of-way to pedestrians and other traffic proceeding as directed by the signal at said intersection.
b. Vehicular traffic facing a steady red arrow signal, with the intention of making a movement indicated by the arrow, 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 a permissive signal indication is displayed.
