(1) Whenever traffic is controlled by traffic control signals exhibiting different colored lights successively, or with arrows, the following colors shall be used and shall indicate and apply to operators of vehicles and pedestrians as follows:

346.37(1)(a)

(a) Green.

346.37(1)(a)1.

1. Vehicular traffic facing a green signal may proceed straight through, make a U-turn, or turn right or left unless a sign at such place prohibits the turning maneuver, but vehicular traffic shall yield the right-of-way to other vehicles and to pedestrians lawfully within the intersection or an adjacent crosswalk at the time the signal is exhibited.

346.37(1)(a)2.

2. Pedestrians, and persons who are riding bicycles or electric personal assistive mobility devices in a manner which is consistent with the safe use of the crosswalk by pedestrians, facing the signal may proceed across the roadway within any marked or unmarked crosswalk.

346.37(1)(b)

(b) Yellow. When shown with or following the green, traffic facing a yellow signal shall stop before entering the intersection unless so close to it that a stop may not be made in safety.

346.37(1)(c)

(c) Red.

346.37(1)(c)1.

1. Vehicular traffic facing a red signal shall stop before entering the crosswalk on the near side of an intersection, or if none, then before entering the intersection or at such other point as may be indicated by a clearly visible sign or marking and shall remain standing until green or other signal permitting movement is shown.

346.37(1)(c)2.

2. No pedestrian, bicyclist, or rider of an electric personal assistive mobility device facing such signal shall enter the roadway unless he or she can do so safely and without interfering with any vehicular traffic.

346.37(1)(c)3.

3. Vehicular traffic facing a red signal at an intersection may, after stopping as required under subd. 1., cautiously enter the intersection to make a right turn into the nearest lawfully available lane for traffic moving to the right or to turn left from a one-way highway into the nearest lawfully available lane of a one-way highway on which vehicular traffic travels to the left. No turn may be made on a red signal if lanes of moving traffic are crossed or if a sign at the intersection prohibits a turn. In making a turn on a red signal vehicular traffic shall yield the right-of-way to pedestrians, bicyclists, and riders of electric personal assistive mobility devices lawfully within a crosswalk, to operators of vehicles making a lawful U-turn, and to other traffic lawfully using the intersection.

346.37(1)(c)4.

4. Notwithstanding subd. 1., a motorcycle, moped, motor bicycle, or bicycle facing a red signal at an intersection may, after stopping as required under subd. 1. for not less than 45 seconds, proceed cautiously through the intersection before the signal turns green if no other vehicles are present at the intersection to actuate the signal and the operator of the motorcycle, moped, motor bicycle, or bicycle reasonably believes the signal is vehicle actuated. The operator of a motorcycle, moped, motor bicycle, or bicycle proceeding through a red signal under this subdivision shall yield the right-of-way to any vehicular traffic, pedestrian, bicyclist, or rider of an electric personal assistive mobility device proceeding through a green signal at the intersection or lawfully within a crosswalk or using the intersection. This subdivision does not affect any authorization for a bicyclist under subd. 2.

346.37(1)(d)

(d) Green arrow.

346.37(1)(d)1.

1. Vehicular traffic facing a green arrow signal may enter the intersection to make the movement indicated by the arrow but shall yield the right-of-way to pedestrians, bicyclists, and riders of electric personal assistive mobility devices lawfully within a crosswalk and to other traffic lawfully using the intersection. Vehicular traffic facing a left turn arrow may make a U-turn unless a sign prohibits U-turns. When the green arrow signal indicates a right or left turn traffic shall cautiously enter the intersection.

346.37(1)(d)2.

2. No pedestrian, bicyclist, or rider of electric personal assistive mobility device facing such signal shall enter the roadway unless he or she can do so safely and without interfering with any vehicular traffic.

346.37(2)

(2) In the event an official traffic signal is erected and maintained at a place other than an intersection, the provisions of this section are applicable except as to those provisions which by their nature can have no application. 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 any such sign or marking the stop shall be made at the signal.
