Sec. 612.

(1) When traffic is controlled by traffic control signals, not fewer than 1 signal shall be located over the traveled portion of the roadway so as to give vehicle operators a clear indication of the right-of-way assignment from their normal positions approaching the intersection. The vehicle signals shall exhibit different colored lights successively, 1 at a time, or with arrows. Red arrow and yellow arrow indications have the same meaning as the corresponding circular indications, except that they apply only to vehicle operators intending to make the movement indicated by the arrow. The following colors shall be used, and the terms and lights shall indicate and apply to vehicle operators as follows:

(a) If the signal exhibits a green indication, vehicular traffic facing the signal may proceed straight through or turn right or left unless a sign at that place prohibits either turn. Vehicular traffic, including vehicles turning right or left, shall yield the right-of-way to other vehicles and to pedestrians and bicyclists lawfully within the intersection or an adjacent crosswalk at the time the signal is exhibited.

(b) If the signal exhibits a steady yellow indication, vehicular traffic facing the signal shall stop before entering the nearest crosswalk at the intersection or at a limit line when marked, but if the stop cannot be made in safety, a vehicle may be driven cautiously through the intersection.

(c) If the signal exhibits a steady red indication, the following apply:

(i) Vehicular traffic facing a steady red signal alone shall stop before entering the crosswalk on the near side of the intersection or at a limit line when marked or, if there is no crosswalk or limit line, before entering the intersection and shall remain standing until a green indication is shown, except as provided in subparagraph (ii).

(ii) Vehicular traffic facing a steady red signal, after stopping before entering the crosswalk on the near side of the intersection or at a limit line when marked or, if there is no crosswalk or limit line, before entering the intersection, may make a right turn from a 1-way or 2-way street into a 2-way street or into a 1-way street carrying traffic in the direction of the right turn or may make a left turn from a 1-way or 2-way street into a 1-way roadway carrying traffic in the direction of the left turn, unless prohibited by sign, signal, marking, light, or other traffic control device. The vehicular traffic shall yield the right of way to pedestrians and bicyclists lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.

(d) If the signal exhibits a steady green arrow indication, vehicular traffic facing the green arrow signal, shown alone or in combination with another indication, may cautiously enter the intersection only to make the movement indicated by the arrow or other movement permitted by other indications shown at the same time. The vehicular traffic shall yield the right-of-way to pedestrians and bicyclists lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.

(2) If a traffic control signal is erected and maintained at a place other than an intersection, the provisions of this section apply except for those provisions that by their nature cannot apply. Any stop required shall be made at a sign or marking on the pavement indicating where the stop shall be made, but in the absence of a sign or marking, the stop shall be made at the signal.

(3) A person who violates subsection (1) or (2) is responsible for a civil infraction.

(4) A vehicle operator who approaches a person using a wheelchair or a device to aid the person to walk at a crosswalk or any other pedestrian crossing shall take necessary precautions to avoid accident or injury to the person using the wheelchair or device. A person who violates this subsection is guilty of a misdemeanor.

(5) A sign prohibiting a turn on a red signal as provided in subsection (1)(c)(ii) shall be located above or adjacent to the traffic control signal or as close as possible to the point where the turn is made, or at both locations, so that 1 or more of the signs are visible to a vehicle operator intending to turn, at the point where the turn is made. An additional sign may be used at the far side of the intersection in the direct line of vision of the turning vehicle operator.

(6) Subject to federal law, a temporary traffic control signal may be located on, over, or adjacent to the traveled portion of the roadway.
